Yearning 4: Zhuge Dali is My Nemesis

Li Yuan spoke again, and everyone subconsciously raised their ears, for fear of missing some important information.

"The key to the proof of the four-color problem can be summarized as the problem of the intersection of two straight lines in a two-dimensional 2-plane.

We can understand it as the connection between points and points to represent the adjacent logical relationship between two areas on the map!"

"If we prove by topology"

In the entire amphitheatre, every word Li Yuan said was like a bell in the morning and a drum in the evening, pulling everyone's thoughts, and time passed by like a white horse.

The expressions of these people at the bottom sometimes fell into contemplation, sometimes their eyes lit up, sometimes they suddenly realized, sometimes they frowned and puzzled, and even as the story went deeper, Li Yuan had to use the blackboard to make people understand.

After all, everyone here is a big touch in the industry. Even if they are proficient in various fields, they have the same goal. Mathematics is about methods.

One after another theorem, one after another formula, thousands of threads can be implicated in one place, and the whole proof process is progressive and clearer.

"To sum up, that is, there are no intersecting straight lines in the two-dimensional 2-plane, but only co-point straight lines.

The four-color problem is confirmed!"

Li Yuan finally came to the final conclusion.

In fact, when Li Yuan explained the second half, everyone had foreseen the result, so at this moment, the applause sounded like thunder.

As the head of the jury of this conference, Jon couldn't help standing up and applauding, and President Li Qing of the National Academy of Sciences was even faster than him.

One person stood up, two people stood up, and three people looked at each other, and the entire ladder taught people all stood up, clapping their hands vigorously, like crazy, there was only one person in their eyes, and that was Li Yuan! Even this is not Li Yuan anymore It is a moment of glory for a person. In their eyes, it knows no borders, and it is a moment of glory for all mankind.

The four-color problem, or the four-color conjecture, was proposed in 185, and since this problem was raised, it has troubled mankind for nearly two hundred years.

Now! Humanity has finally conquered this problem! The cross-examination meeting has directly turned into a personal show of Li Yuan's exaltation. Alex's expression was quite tangled and struggling. He recognized Li Yuan's conclusion and also recognized Li Yuan's strength.

At the same time, I also know that this is a great progress for all mankind! But when I put it on myself, I really failed. I took the initiative to organize this cross-examination meeting, and kept saying that Li Yuan was a grandstanding actor.

Now it's your turn to be slapped in the face! Even if these people haven't remembered to laugh at themselves, it is conceivable that this is a sure thing. Of course, being laughed at is insignificant.

The most heart-wrenching thing for Alex is that this time, the Fields Medal seems to be [-]% missed by him. The five or six years of his hard work and hard work were all in vain.

Everyone started to exit in an orderly manner, these... Mathematicians also need a quiet space to revisit the whole process of replay, and the National Academy of Sciences assumed the camera at the beginning.

Video recordings will be used, and then a complete paper will be compiled as quickly as possible, which will be submitted at the next mathematics conference.

Jon and Li Qing are really too old, and the four-hour explanation, if combined with the previous proof of Catalan's conjecture, the process has exceeded five hours.

The current time is 14:[-] in the imperial capital time! I can't hold it anymore, even if my heart is excited, but my physical condition does not allow it to continue to endure, but many young researchers are still surrounding Li Yuan, wanting to communicate further.

Li Yuan is about to vomit blood, I just want to be a salted fish! Why do you think of me as a scholar? Dean Li Qing shooed all these people away, so Li Yuan was able to leave, and directly arranged a special car to take him home. It was definitely a restless night.

The entire mathematical world has been turned upside down. These.... the scholars who attended the meeting kept spreading the news. After all, because of the time difference, it is now broad daylight! It is more convenient Spread the word! When I got home, I took a shower, and lay in bed, and then I picked up the phone. Zhuge Dali said before that he wanted Li Yuan to call him back when he was done! Sent a WeChat message: "Have you gone to bed? It's time to get up and pee!"

The video call popped up in the next second, Li Yuan connected directly in surprise, and then watched Zhuge Dali appear refreshingly, my God! Is this still my little brother? How does it feel to grow up!

"Did you just come back or just woke up?"

"Why did you contact me now?"

"I've been waiting for you to wait until it's dawn!"

"I asked you what to say, but you... squeak... ah you!"

"What are you looking at?"

Zhuge Dali asked questions like a barrage of cannons, one can imagine how tormented this period of time was, and when he asked, he suddenly felt that Li Yuan's eyes were not quite right.

"what!"

She screamed subconsciously, then quickly pulled the blanket over and wrapped herself tightly: "If you look at me again, I'll gouge out your eyes! You are too lustful!"

What does it mean to not know the true face of Mount Lu, just because in this mountain, I usually see Dali's classmate as ordinary and unremarkable, even if this girl wears pajamas, I have seen it a few times, but it is obvious that the clothes she came to do the show have been selected.

It's not as relaxing as the one I wear at home at all. Well, the style is more loose and comfortable, and it has just been there: I can't fall asleep by tossing and turning on the bed, which makes the clothes slightly out of shape.

This also gave Li Yuan a chance to take a glimpse! "I'm a man, please! Haven't you heard that sentence? Eighty percent of men are lecherous."

Li Yuan smiled.

"You're too embarrassed to laugh at why you don't do that... [-]%%% man"

Zhuge Dali glared fiercely, wrapping himself more like a zongzi.

"I'm that... [-]%% man! By the way, I forgot to tell you, the remaining [-]%% men are not lecherous, but very lecherous!"

Li Yuan chatted with Zhuge vigorously, without pressure, after all, everyone is so familiar! "You are going to be mad, you and I will wait for you until the middle of the night, just... wait for you to be angry with me"

Zhuge Dali couldn't wait to come and give Li Yuan two punches.

"Okay! Don't wait, go to bed early! I'm sleepy too!"

Li Yuan's direct sentence made Zhuge Dali annoyed again, the girl had already begun to gasp for breath: "What did you say, you asked me to sleep earlier, you clearly know what I want to hear, and now I will forgive you if you say it quickly. You just spied on me!"

"No way, I'm a peeping here, I'm all open and honest! Stop! Don't worry, I said! I said!"

Li Yuan teased the girl for a few words, and finally began to get to the point.

He started to bring himself to the Institute of Mathematics, and then told a group of researchers about the proof process of Catalan's conjecture, which was concise and to the point, but Zhuge Dali couldn't help but marvel: "Is it true that no one refutes you? It means that you have proved successful. Oh my goodness! Lee Won, do you know what that means?"

Seeing Zhuge Dali's excitement, Li Yuan wondered if this girl knew that not only did Catalan get it done, but even the four-color problem proved a success, would it directly "mean something"?

Li Yuan raised his eyebrows vigorously towards Zhuge.

"You can, let me ask you, if you are old or dead, what kind of evaluation do you most hope to receive in future generations?"

Zhuge Dali directly explained his thoughts through a question.

"If I die like that, I think they'd better say"

Li Yuan raised his hand and rubbed the bridge of his nose: "Hey, hey! Look! He moved, moved, and lived again!"

Li Yuan's expression was vivid and vivid, and the angry Zhuge Dali had the urge to vomit three liters of blood, and almost threw the phone out: "Are you... a little serious, don't you think that the evaluation of you in future generations will affect your math skills? Evaluation of Contributions in the Field"

"Oh! This is it! How can I say it! If this is the case, I'm really afraid that when the college entrance examination is over, people will scold me and say that it is because of me that mathematics is so difficult!"

Li Yuan has a deep understanding,,,, when he was a student, he was full of tears about this theorem, that...law, this principle, that...phenomenon.

I really feel that the characters in these textbooks are torturing me to the death! Alas! I didn't expect that I would eventually become the person I hate! Will someone stab their own little person with a needle "You save it! Your... card Taran conjectures, it is not suitable for college entrance examination questions at all!"

Zhuge Dali rolled his eyes at Li Yuan, and suddenly thought: "Hey! That's not right! Then you shouldn't have come back so late. Did Academician Chen invite you to dinner? It's not right! what!"

"Hey! This is a long story! I communicated with a group of researchers over there, handed it around, and who knows, a group of foreigners came, one named Jon, who is also the head of the mathematician conference!"

Li Yuan said the name of this person, Zhuge Dali frowned slightly: "Jon, is it Jon McMullan, he seems to be a professor at Cornell University!"

With a swish, Dali's eyes suddenly lit up: "He is not the head of the mathematician conference, he is the head of the Fields Medal jury!"

"Why did he come to you, right! My tutor said that your research results are enough to enter the selection of the Fields Medal. When people come to you, do you think you have a show?"

Zhuge Dali was even more surprised! Even though she didn't specialize in mathematics, she still knew very well about the Mathematician Conference and the Fields Medal, and the more she thought about it, the more reliable she felt.

Before that, she could never have imagined that Li Yuan had suddenly become a mathematician, and he was still a mathematician who could compete for the Fields Medal! This is enough to worship herself! "That's because there is a The guy named Alex, if he says I'm an actor, or that I can't prove the Catalan conjecture, that's... he's pushing a group of people over here to make trouble! He has to hold a cross-examination meeting!"

The Alex that Li Yuan mentioned, classmate Dali didn't have much impression of the name.... But I heard Li Yuan say that this group of people came to ask for trouble for a cross-examination meeting. , still inexplicably a little nervous: there must be a lot of mathematicians in this cross-examination meeting, and all of them are aimed at Li Yuan alone. Then what do you do after agreeing?"

Li Yuan nodded: "Yes! The soldiers will block the water and cover the soil,,,,, I immediately agreed, and when I got angry, I also proved the four-color conjecture!"

"Oh! That's good! What are you talking about? Four-color conjecture"

Zhuge Dali was unaware that the blanket he was wrapped in slipped again, and the little brother who had grown up entered the camera again, his breathing rhythm was chaotic, up and down: "Li Yuan, stop talking nonsense! Can you be more serious?"

The voice trembled a little.

Hide, recommend, share!

"Donor, calm down! I can already see that you have a big omen!"

Li Yuan avoided letting Zhuge Dali say that he was lewd, and directly reminded him.

But obviously, Zhuge Dali had been directly shocked by the four-color question, and he just stretched out his hand to wrap the blanket again, and couldn't help but directly asked: "Are you talking nonsense just now? … hurry up and say it!”

The four-color problem is not only ranked among the top ten mathematical problems, but it can also sit firmly in the top three. One can imagine the status of this problem in the field of mathematics.

Just like Mount Everest, it is unreachable, and countless people disappear directly on the snow during the climbing process.

The same is true for the research on conjectures of mathematical problems. Countless mathematicians have worked hard to solve the problems, but they are nothing until they come up with results! It is even said that there are not a few mathematicians of this type, and they have been working hard for decades. Forgetting to eat and sleep, maybe at the end, there is nothing left.

Just like what Zhuge Dali said before, no matter what...

What field, people can remember, only the first place, and the rest, no matter...

Whether it is the second place or the nine hundred and ninety-ninth place, there is no difference at all.

"Of course I'm not kidding! The four-color problem, I solved it easily!"

Li Yuan shrugged his shoulders at the camera: "You don't know the situation at that time"

, Li Yuan held a mobile phone in one hand, and the other hand also posed a wave shape and began to explain further: "At that time, the entire venue was literally crowded with people, one after another, and it was roughly estimated that there were several thousand people!"

"Wait...! Didn't you say that... the classroom is 500 people and [-] people?"

Zhuge vigorously frowned.

"Did I just say okay, don't care about these details!"

Li Yuan scratched his head subconsciously: "Anyway...you only need to know that the people sitting below will make me stunned!"

"Have you heard of thunder and know what thunderous applause is? These people were all shocked at first, but after they reacted, they all began to applaud and cheer from the heart!"

"The applause is long-lasting, and it goes around the beam for three days without stopping."

Li Yuan made an artistic description here, and the more Zhuge Dali listened, the more ambiguous he felt: "Stop, stop, stop! Li Yuan, what you said is true or false."

After all, my understanding of Li Yuan is quite in-depth, and I know that although this guy often runs the train with his mouth full, it is not always like this, and he will talk about some profound topics from time to time.

This kind of appearance of being false when it is true and false, really makes Zhuge Dali doubtful: "We can have a serious sentence, if you don't say it, how can you speak well?"

Li Yuan suddenly became serious: "That's it! You let me sleep!"

"Why are you so annoying.

Me, if you play hooligans with me again, I'll be really angry!"

Zhuge gritted his teeth vigorously.

"Uh!"
