The passionate years starting from the college entrance examination

Chapter 313, Killing like crazy!

In October 1965, Hong Kong Ta Kung Pao immediately reported on the front page of a mathematics seminar held in the capital.

"Thousands of mathematicians gathered at Peking University, and Fermat's Last Theorem has been confirmed: Yesterday, October 5th, the world-renowned Peking University mathematics professor Chen Guohua held a mathematics report in the Peking University auditorium."

"The report will be divided into two days. On the 5th, the report on the three papers proving Fermat's last theorem has been completed."

"After repeated confirmation by top mathematicians such as Andre Weil, Gelfand, Shafarevich, Alexandrov, Hassler Whitney, and Chen Shengshen, as well as thousands of other mathematicians present, The researchers’ determination was unanimously proven by Fermat’s Last Theorem.”

“One of the most difficult tasks in mathematics, this problem is simple in its formulation and way of thinking, but extremely difficult to prove.”

"The proof of Fermat's last theorem marks a great achievement and an important milestone in mathematical research."

"Andre Weil called Chen Guohua the greatest mathematician of the 20th century and a blessing to us mankind"

"Gelfand said that the various mathematical tools proposed by Fermat's Last Theorem have had a profound impact on algebraic geometry, number theory, harmonic analysis, topology and other branches of mathematics, and have promoted the development and progress of these mathematical fields."

Ta Kung Pao published a newspaper reporting the incident in detail, and other newspapers were not far behind.

Even the Hong Kong Commercial Daily reported the matter and also praised it.

Chen Yuanchao knew very well that Chen Guohua, professor of mathematics at Peking University, was his uncle, so he would definitely have to praise him vigorously.

In comparison, other newspapers such as Xinhua News Agency are much more conservative and modest, and they are strict in reporting.

Overseas, North American newspapers such as the Wall Street Journal, Washington Post, New York Times, Chicago Tribune, Boston Globe, New York Post, and Los Angeles Times have all followed suit. Just like celebrating the New Year, I fried it over and over again several times.

The story was also reported in European newspapers such as The Times, as well as elsewhere in Tokyo and Moscow.

Fermat's Last Theorem is still very influential around the world, or it is a powerful subject that Europe can master.

After all, if you ask them to talk about history, they will definitely be blind.

The history of the West is really hard to describe, especially in the archaeological field, where fraud has occurred.

The world was once again abuzz with the news that Fermat's last theorem was proved, and the capital was also very lively.

Many mathematicians don’t want to leave just because Chen Guohua fulfilled his promise and really communicated with many people.

However, he only has time in the afternoon every day, so not everyone can communicate with Chen Guohua.

And this so-called exchange is actually similar to a report meeting, it's just a question and answer situation.

Even so, many people were conquered by Chen Guohua's powerful brain power and ultra-broad knowledge.

No matter in any field of mathematics, or even in other subjects such as physics, he has a very good accumulation of knowledge.

It's no wonder that Chen Guohua dared to "boldly" say that starting from next month, he will publish three to five papers every month.

This level of knowledge is really awesome.

Erdez has become a little fan, not to mention Van Oko, Davenport, 1. Klaus Friedrich and Selberg, Homandel and Eugenio Karabi. Six people.

These six people have been at Peking University for six years and have already regarded themselves as part of Peking University.

Originally, they said that it would be difficult to see Chen Guohua devote himself wholeheartedly to mathematics research in this life.

Unexpectedly, it was because of the International Congress of Mathematicians that Chen Guohua took the initiative to propose the challenge.

Nowadays, everyone is waiting for Chen Guohua’s paper.

Because of this, Michael Attiyah, Paul Cohen and others have expressed their intention to stay in the capital for a longer period of time.

Jianguo Street suddenly became a lot more lively.

Because people like Michael Attia and others want to stay in the capital for a long time, they definitely need to adjust the visa period.

Therefore, this inevitably requires troublesome negotiations with the people above.

Qiu Zongyue has not seen anyone in recent times. He is probably busy with other things.

The week flew by, and Chen Guohua also ended the mathematics exchange and returned to normal work.

But Michael Attia and the others still did not leave Peking University, but chose to stay.

Some went to Peking University, some went to Tsinghua, some went to Renmin University and other universities.

After all, if they stay, they will definitely need to eat. They can't rely entirely on royalties, right?

So, isn’t it normal to have a part-time job?

There is still a need for communication and coordination from the people above.

In short, because of Chen Guohua's speech, the capital has become very lively recently.

People like Michael Attiyah, Hironaka Heiyu, Alexander Grothendieck and others are not bad, because they are the favorites for next year's Fields Medal.

Naturally, they stayed because they wanted to know the papers published by Chen Guohua as soon as possible, and then determine the quality and influence of these papers to determine whether they would be affected.

In addition, they also followed the advice of Erdesh and others, because Chen Guohua would come to Peking University from time to time to teach students like Chen Shuxing and exchange mathematics with Erdesh and others.

For Michael Attia and others, it would definitely be a good thing to be able to communicate with Chen Guohua.

It may not be of much help to Chen Guohua, but for young and middle-aged scholars like them, it would certainly be a very good thing if they could make more achievements at this age.

In the history of the original time and space, Michael Atiyah posted a preprint of his proof of the Riemann hypothesis in 2018, when he was eighty-nine years old.

One can imagine how dedicated he is to the study of mathematics.

Even Alexander Grothendieck was led astray. He stayed in the capital and did not return to Europe.

After all, according to the history of the original time and space, he will not go to Moscow to receive the award next year, but will travel to Haizhou City, and then become a radical environmentalist.

When it comes to environmental protection, Chen Guohua finds it quite ironic.

Originally, environmental protection was a very good thing, but in Europe, environmental protection has been completely distorted.

Later, Chen Guohua learned that the food safety standards in Europe actually allowed food manufacturers to freeze, dry or crush crickets and add them to their products.

And this law will also apply to tiny mealworm larvae!

Really, it’s so outrageous that he opened the door for outrageous people.

So why did the standard become like this?

Isn’t it just a fool’s errand made by these so-called environmentalists? They insist on protecting rats and other wild animals.

Good guy, the entire Europe is infested with rats, locusts and other rodents, so is it normal for rice, flour and other foods to be adulterated with some insect corpses?
In the original history of time and space, why was it that when Tesla went to Shanghai to build a car factory, he was able to complete it in a very short time, but suffered a huge setback in Berlin?

Ugh!
It is really ironic that we should protect the environment well, but in the end, mankind itself will suffer.

But in comparison, what the Holy Mothers in Northern Europe did was even more shocking.

And in North America in later generations, it has long been common for people to slap themselves in the face.

From these things we can see how chaotic things are in Europe and the United States.

Reality is always more magical than the 'artwork' processed by art.

Peking University has gained hundreds of very capable mathematicians or master's and doctoral students, and Chen Guohua is very happy to see this happen.

But the sequelae is that his own rest time has been shortened a lot.

"Dad, are you writing an article again?"

In late October, in the study room of Chen's family in Cuihua Hutong, Chen Si came to her father holding a stuffed toy knitted by her grandmother, and asked curiously with her eyes wide open.

The little one already knows that her father has been very busy recently. Whenever he gets home, he usually goes into the study to write some paper.

So Chen Si, who wanted to play with her father, couldn't stand it anymore, so she secretly ran over to find her father.

Chen Guohua looked away from the computer monitor, then picked up the little guy:

"Yes, dad needs to write an article, but dad will finish it quickly. Can you wait for my dad for another ten minutes?"

"it is good!"

It was only ten minutes, so the little one sat in her father's arms holding the toy.

But with Chen Guohua holding the little guy in his arms, his work efficiency dropped a lot.

After all, although the little guy is very well-behaved and basically doesn't move much, with an extra child in his arms, Chen Guohua can't be distracted.

So after a while, he paused and stayed with his children first.

The work is never done!
After hugging the little one and leaving the study, Chen Guohua went out to the living room to play with her and her elder brother, which confused Yu Moli and the others.

"Brother Guohua, didn't you say you wanted to write a paper recently? Why are you still coming out to spend time with your children?"

About this incident, the whole family has learned about it through newspapers.

Because what Chen Guohua said in the auditorium was reported by the media.

What's more, there are foreigners like Michael Atiyah. Yu Moli graduated from Peking University, so of course he knows these things very well.

"It's a good balance between work and rest. Besides, writing a paper is not difficult for me, it's just more time-consuming."

Chen Guohua said with a slight smile, his words full of confidence.

Many mathematicians particularly like to use paper and pen to write papers, so the saying "precious manuscripts" once appeared.

But Chen Guohua himself is very accustomed to using computers to edit, because only in this way can efficiency be maximized.

It's not that his writing ability is poor, but that after having a computer, he became more accustomed to high technology.

It is very simple for him to use a computer to write papers.

What's more, most of these papers are in the biological hard drive, and he directly 'copied' them, as simple as he wants.

"That's right. You should have done this a long time ago. Seeing that you have been so busy recently, we are all worried about you..."

Yun Wanshang answered from the side, and the two little guys Chen Wei and Chen Si also echoed:

"Dad, Dad, we are also worried about you..."

"Okay, okay, dad knows." Chen Guohua hugged the two brothers and sister, feeling very satisfied.

Yu Moli, on the other hand, laughed and scolded them as two clever little guys who were very good at coaxing people.

Both children are a bit bigger than others. As they grow older, they become smarter and know how to 'play by ear'.

Isn't it because Yu Moli's belly is gradually getting bigger, so the two brothers and sisters know how to be considerate of their mother, and often help with things they can do.

Children who are four or five years old are really young if you say they are young, but they should be sensible if you say they are older.

The two brothers, Chen Wei and Chen Si, are not just sensible and well-behaved, they are also smart and extremely popular.

Seeing the adults laughing, the two children also laughed.

After spending some happy time at home, November soon entered.

After entering November, the weather in the entire capital began to plummet a lot.

But compared to the quick-freezing mode in Beijing, the mathematics community has become popular because of this.

why?
Because Chen Guohua actually produced five papers as promised.

Among these five papers, two are staged papers on the Riemann hypothesis. Once verified in detail, their value will never be lost to the zero-point conjecture.

The other three papers are algebraic curve and surface topology problems, partial differential equation boundary value problems, and general boundary value problems.

All five papers are top mathematics papers of very important significance and have special significance in promoting the development of mathematics.

Therefore, after these five papers came out, it was like throwing five depth bombs, which first shook the entire mainland mathematics community upside down, and then spread to the global mathematics community.

Peking University, mathematics department office, Michael Atiya, Alexander Grothendieck, Paul Kern and other mathematics researchers all gathered in this office, quietly looking at Chen Guohua's five papers.

Not far away, Erdez was amazed, "It must be the jury of the International Congress of Mathematicians. Only they can allow Professor Chen to produce so many papers at once."

"Professor, you are right. I think our teacher really needs this kind of pressure so that he can write more papers."

Chen Shuxing on the side also echoed.

Although he is a student of Chen Guohua, in fact, many times he consults Erdez instead of studying with Chen Guohua.

To be honest, I haven’t graduated with a PhD in five years, which is really a bit slow.

This has a lot to do with Chen Guohua's "irresponsibility". If it were other professors, many students would have graduated long ago.

"Professor, there are several questions in this paper on algebraic curves and surface topology that I don't quite understand. Can I ask you first?"

Bai Ronggen brought the paper to Erdez, who nodded directly and said there was no problem.

Since Chen Guohua has written so many papers, isn't it normal for him to ask Erdesh to help?

As a person who loves to pursue mathematical truth, Erdesh hopes to see Chen Guohua's current situation and hopes that the latter can continue.

As for helping Chen Guohua teach his students, this seems to have been his job from the beginning.

The five of them, Jiang Boju, seemed to have two teachers. In fact, Chen Guohua, the teacher, was extremely irresponsible.

Of course, Chen Shuxing and the others can understand, after all, Chen Guohua is really very busy.

"Next year's Fields Medal, we are really in danger."

After reading Chen Guohua's papers, Guangzhong Pingyou said with a bitter look on his face.

The reason why he is so frustrated is because among all the candidates for next year's Fields Medal, he is the one with the biggest crotch.

Let’s not talk about Chen Guohua. If his name is not included in next year’s Fields Medal, many mathematicians will definitely not be happy.

Not to mention that Chen Guohua had won the award in 1962 and should not have won the award again in 1966.

Since the Fields Medal was established in the 1930s, there have been no regulations in this regard.

Therefore, Chen Guohua can definitely win the award two years in a row, even in 1970 or 1974. As long as he has enough achievements and is under the age of forty, he can keep winning.

The other three, Michael Attiyah, Alexander Grothendieck and Paul Cohen, are relatively safe.

First let’s talk about Michael Atiyah. In 1963, he jointly proposed the index theorem with Isadore Singer of MIT, which is correctly called the Atiyah-Singer index theorem.

This theorem, which connects analysis and topology - a fundamental connection that is important in both mathematics and physics.

In the history of proto-spacetime, methods derived from the index theorem unexpectedly played a role in the development of string theory, an attempt to reconcile the large-scale realm of general relativity and gravity with the small-scale realm of quantum mechanics.

Next is Alexander Grothendieck, who is a rising star in the European mathematics community, but he has not received systematic teaching, which is very different from many formal mathematics researchers.

In the 1950s, he created a new version of the Riemann-Loch theorem, revealing the hidden relationship between the topological and analytic properties of algebraic varieties.

In the early years, he created the Grothendieck inequality and its relationship with the absolute sum operator in the field of functional analysis. But unfortunately, these mathematical tools and methods of his mostly used algebra and category theory, which was different from the mainstream view. Therefore, in this era, Grothendieck's fame and talent in mathematics were ignored and underestimated.

In the original history of space and time, Grothendieck's research methods, tools and results on functional analysis did not show its power until many years later.

In the past few years, he collaborated with Jean Dieudonné and others to write "Fundamentals of Algebraic Geometry", and this masterpiece also brought his career to its peak.

Even in later generations, he was hailed as one of the greatest mathematicians of the twentieth century.

The last person, Paul Cohen, completed the first of the twenty-three questions raised by Hilbert at the beginning of the twentieth century, which was Cantor's continuum hypothesis.

Paul Cohen showed in 1963 that the truth of the continuum hypothesis cannot be determined within the Zermelo-Frenkel axiom system.

In comparison, Hironaka Heiyu used many tools to analyze various situations in detail in 1964, and finally used multi-step induction to completely solve the singularity of algebraic varieties of any dimension. Solve the problem and establish the corresponding theorem.

Therefore, no matter in every aspect, he is indeed inferior to Paul Cohen and the other three.

Not to mention comparing with Chen Guohua.

Today, Chen Guohua is already recognized as the new emperor of mathematics in the mathematics community, and last month he announced that he would publish three to five papers every month in the next period until the members of the International Congress of Mathematicians jury agree. He would not end until the 1970 conference was moved to the capital.

In other words, Chen Guohua will continue to explode and come up with more and better papers.

How can this compare?
Perhaps Guangzhong Pingyu can only pray for the class of 1970.

And he was born in 1931, so if he couldn't win the award in 1970, then he would have no chance of receiving the Fields Medal in this life.

When Chen Guohua's five papers caused a major earthquake in the entire mathematics community, he himself hid in the aerospace engine laboratory of Zhenhua Research Institute and was busy with his work.

He wrote the paper in his own non-working time, so it did not take up working time.

Therefore, neither the civil aviation passenger aircraft project nor the two aviation helicopter projects on the next street were delayed.

As time goes by, in mid-to-late November, the Jiuquan Satellite Launch Center began its second launch of low-Earth orbit satellites.

It has only been two months since the last satellite was launched, and now another satellite has been launched, which can only be said to be a waste of money.

The mainland's economic development is not good, and the money bag is a bit thin, but it is really supportive of scientific research.

China Resources Corporation went all out to support and earn a lot of profits from overseas. At the same time, white glove companies like Chen Yuanchao and others gradually began to show their power.

Take Chen Yuanchao's own company as an example. In less than a year, it has delivered more than 300 million U.S. dollars in supplies to the mainland.

Although not every white glove company has such a terrifying profit scale, on average, each company has a profit of tens of millions of dollars, which is already very scary.

With so much capital support, the mainland certainly has more funds to complete these scientific research tasks.

For the second satellite launch, Chen Guohua did not go to the scene, but checked through a video call.

He is responsible for too many projects, so it is naturally impossible for him to do everything by himself. Otherwise, no matter how healthy he is, he will not be able to handle such a heavy workload.

With the previous experience of the first satellite launch, the entire process of the second launch was extremely smooth.

However, Chen Guohua insisted on watching the entire launch process. It was not until the satellite was suspended in space and contacted the ground that he truly breathed a sigh of relief.

Satellite launch missions are no joke. Once they explode, the money lost is nothing. The most important thing is that the confidence of scientific researchers will be greatly affected.

These rockets now are all disposable, not Musk's recyclable rockets, and the cost will be much lower.

The second rocket also successfully launched the satellite into space. With these two successful experiences, it will be of great reference significance for the subsequent launch of the third medium-altitude or high-orbit satellite.

All the scientific researchers were full of confidence, and Chen Guohua was relieved.

As long as the satellite launch can go smoothly and the satellites needed by the mainland can be launched step by step, it will be immeasurable for the development of the entire mainland.

North America, Institute for Advanced Study, Princeton.

Hassler Whitney was still very shocked when he saw the five papers published by Chen Guohua.

"Why don't you want to come to our North America? It would be great if you came to our North America?"

For a true North American, working to promote the development of mathematics in North America is what he wants to do most in the rest of his life.

After World War II, North America and Moscow fought fiercely, and the same was true in the mathematics community.

There are currently two major mathematics centers recognized in the world, one in Moscow and the other in Princeton.

But since von Neumann's death, only a few people like him and Andre Weil have been able to support Princeton, and Chen Shengshen is the only one.

But what about Moscow?

Not to mention the most awesome Kolmogorov, there are Gelfand, Shafarevich, Markov, Alexandrov, etc., all of them are very awesome.

Therefore, it is not unreasonable that Moscow’s aerospace level is slightly better than that of North America.

Hassler Whitney wanted to win over Chen Guohua and come to North America, a place where people are obsessed with life and money, but failed.

In fact, if Chen Guohua wanted to satisfy his other desires, he would have left the capital long ago. Why would there be any need to wait until now?

That place in North America is not my hometown. If I go there, I will only be bullied.

"Hassler, stop dreaming. It is impossible for Chen from China to come to North America. We should read his paper carefully to see if it is true as he said. Another report meeting is needed."

Kurt Gödel spoke, and Hassler Whitney came back to his senses, shook his head, and continued to check the paper.

As the top theoretical research institution in North America, the Institute for Advanced Study in Princeton is very famous.

Einstein, von Neumann, Oppenheimer, etc. are all members of this institute, and many scholars have made the most important scientific research achievements in their lives here.

Andre Wey said nothing, but looked at the paper carefully.

After half a day, they all finished reading it. The paper was impeccable. For top mathematicians like them, they could finish it quickly.

Although they have not yet carefully opened and reviewed these papers, Andre Wey and others have a strong intuition that there is nothing wrong with the papers.

In this way, Chen Guohua really fulfilled his promise.

Therefore, we can’t let everyone go to the capital again to attend the report meeting, right?

Or should the 1970 International Congress of Mathematicians be held in Beijing?
For a time, Hasler Whitney, Andre Weil, Kurt Gödel and others all had a headache.

Compared with them, Nevinlinna, Gelfand, Petrovsky and others on the jury really didn’t know what to do.

"Teacher, do we also have to vote for it?"

Over in Moscow, Gelfand looked at his teacher Kolmogorov and asked curiously.

Now, everyone in the Moscow mathematics community knows that Brezhnev wants to assassinate Chen Guohua.

Helu has had this tendency since before.

What's more, now?
Although Gelfand and other Moscow mathematicians did not know how talented Chen Guohua was in invention and creation, how could a person who was often talked about by Brezhnev be a mortal?
For those who are engaged in pure mathematical theory research, it is best not to touch those messy things.

In particular, Chen Guohua has such a high talent in mathematics and is so versatile. Wouldn't it be great to be so dedicated to research and promote the development of mathematics?
After all, this is a temptation enough to go down in history!
"It depends on what you think." Kolmogorov smiled and shook his head and said:
"We don't want to get involved in other things, but if it's something that promotes the development of mathematics, we are bound to do it."

"I have never met China Chen, but from his papers, I can see his strong ambition."

Hearing their teacher's words, Gelfand and others were immediately stunned: When did the teacher become such a genius?

But after thinking about it, they didn't think there was anything wrong with it, because that's exactly what Chen Guohua did.

Take a look at the papers he wrote. Each paper is of very high quality, but covers different fields.

This method of integrating algebraic geometry, topology and other different branches of mathematics is really not something that ordinary people can learn.

Even if Poincaré were still there, I'm afraid he would be willing to be defeated, right?

While Gelfand and the others were actively discussing the papers about Chen Guohua, Brezhnev was like an angry lion, furious at Bandrovsky and others.

No matter how loud the slap on the chest was before, this slap in the face hurts now.

Not only was Chen Guohua okay, he published a new paper and even launched a second satellite rocket.

Why?
How could that poor and backward agricultural country in the East launch satellites one after another in just a few years?
Not only Brezhnev couldn't figure it out, but Lyndon Johnson couldn't figure it out either.

"Lundberg, have you investigated clearly? Where do they get their technology from? Aerospace, rocket technology, etc. are not that simple."

Lundberg, who was named, helplessly spread his hands and said:
"President, the time and space our people can move freely is very limited, so we don't have much information available."

"Judging from the daily life of ordinary people in the capital, the capital here is definitely far behind us, but they are very energetic."

Lyndon Johnson waved his hand and interrupted:

"You don't need to analyze it. I have also been to the capital. I am not blind. Of course I know this. What I want to ask is those arsenals and China Resources. How is your investigation going?"

This kind of competition, of course, will use any means.

What's more, China Resources is so profitable. If Lundberg and the others didn't mean to cause trouble, it would be absolutely impossible.

But it is difficult. China Resources will not recruit staff from outside at all. All people are recruited from the mainland.

Therefore, Lundberg and the others could only stare blankly and use other methods.

As for other methods, there is not so much information that can be obtained, and the danger is greater.

For example, several staff members that Lundberg bribed were all wiped out in less than half a year.

When asked, Lundberg had no choice but to say that he would review it carefully.

"Okay, let's take a closer look at how to deal with Chen Guohua." Lyndon Johnson waved his hand impatiently and brought the topic back.

"I remember, do we have Chinese people joining the army? Can you select a group of them to go to your department for special training? Then disguise yourself and let them approach Chen Guohua."

This proposal was unanimously approved by everyone, but there was a problem in how to select personnel.

Being able to get close to Chen Guohua is very critical.

However, since Chen Guohua is so patriotic and likes to persuade mathematicians like Chen Shengshen to return to the mainland, then let him do it.

While they were busy plotting, Chen Guohua dumped Wang Zha again.

He proved a conjecture about the connection between the arithmetic properties and analytic properties of Abelian varieties that was proposed only a few years ago, namely the Behe ​​and Svenaton-Dyer conjecture.

After seeing the title of the paper, everyone took a breath.

Chen Guohua went crazy!

The Behe ​​and Svenaton-Dyer conjecture is that given an Abelian variety on the overall domain, it is conjectured that the rank of its Modal group is equal to the zero-point order of its L function at 1, and its L function is at 1 The leading coefficient of the Taylor expansion has an exact equation relationship with the finite part size of the Modal group, the free part volume, the period of all prime positions, and the sand group.

In the history of the original time and space, this conjecture was also one of the seven major conjectures of the millennium.

It is difficult to verify, but now it was taken down by Chen Guohua?

It only took a few years before and after. Wouldn't Chen Guohua be a quick shooter?

As early as 1901, Poincaré proposed a conjecture: the group composed of rational points on the curve is a finitely generated Abelian group.

In other words, the binary operations on this group are commutative, and it is completely possible to take a finite number of elements from this group to form a set. All elements in the group can be passed through the elements of the binary operations and inverse operations defined above. generate.

By 1922, the British mathematician Model proved that the group E (Q) was finitely generated.

After that, other mathematicians successively proved the Riemann hypothesis on elliptic curves, which is Hassey's theorem.

Hassey's theorem is actually that the number of local solutions Np of an elliptic curve modulo each prime number p is not much different from p, so they consider the relationship between Np divided by p and the algebraic rank r when calculating.

The calculation results succinctly show their relationship, which is also the "original version" of Behe ​​and Svenaton-Dyer's conjecture.

After World War II, Andre Weil proved the Riemann hypothesis on the algebraic field, and thus proposed the Riemann hypothesis of general varieties, the famous Weil hypothesis, leaving four conjectures.

By 1, the British mathematicians Behe ​​and Svenaton-Dyer jointly constructed the L(E, s) function of the elliptic curve E. They compared the zero point of the function at s= with the elliptic curve E. The relation between rational points is given by an abbreviated BSD conjecture.

In other words, this conjecture has only been around for a few years, but Chen Guohua can't wait to start with it?
For a time, the entire Peking University Mathematics Department fell into a strange calm.

Not only Peking University, but also other universities such as Tsinghua University.

Since October, a few hundred foreign mathematics researchers have stayed in the capital, and these people have been assigned to nearby universities.

However, they had only accepted the teaching task for a few days, but they were tortured to death by the papers published by Chen Guohua.

Fortunately, Chen Guohua will return to Peking University once or twice every month for academic exchanges.

So everyone is looking forward to this academic exchange in December.

In December in the capital, it is already snowing heavily, and the outdoor temperature can drop to about minus ten degrees.

But compared to the cold weather outside, it was as warm as spring inside the auditorium of Peking University.

Chen Guohua came to the auditorium as scheduled. Looking at the thousands of professors, students and others sitting under the stage, he couldn't help but smile:
"I originally wanted to have a brief exchange and improve each other, but I didn't expect you guys to be so enthusiastic and so many people came."

"Okay, let's stop talking nonsense. What do you want to talk about?"

There were a lot of voices in the audience. Some said they wanted to hear the two papers on the Riemann hypothesis. Some said it was about algebraic curves and surface topology. There were all kinds of voices.

It seems that everyone has reached an agreement and hopes that Chen Guohua can talk about the papers he produced in November and December.

Because these papers, no matter which one, are full of cards.

Seeing this scene, Chen Guohua was speechless. Where was the promised exchange?

There were only a few top mathematicians present, and he was not interested in telling them about those papers, because he would never be able to understand more than twenty people.

So he rejected everyone's proposal, turned around and wrote on the blackboard:
"Let's talk casually about boundary value problems in partial differential equations. Not about my thesis, but just casually."

After everyone heard this, they stopped making noises and listened to his lecture quietly.

Chen Shuxing, Jiang Boju and others in the audience were taking notes very seriously.

As a mathematics researcher, you should remain very interested in all mathematical tools, which is what Chen Shuxing and others did.

Although Chen Guohua published so many papers in succession and proposed many mathematical tools, Chen Shuxing and the others were not able to learn many tools.

In fact, they are very satisfied just by learning the mathematical tools of the Poincaré-Chen Guohua theorem.

It's just that their teachers are so awesome. As students, Chen Shuxing and Bai Ronggen certainly can't lag too far behind.

During this mathematics exchange, Chen Guohua was lecturing most of the time, and some people raised their hands to ask questions from time to time.

In the end, Chen Guohua alone faced questions from hundreds of people, and he had to give answers to all of them.

Even so, Chen Guohua was still at ease and did not appear too panicked.

After the exchange ended, it was already dark outside, but everyone still seemed to be still unfinished.

Just as Chen Guohua walked out of the auditorium, Lu Qiaoshan, editor-in-chief of the Mathematics Journal, who had been waiting at the door for a long time, stopped him with great joy.

(End of this chapter)
