The end of technology.

Chapter 62 Why don't I teach you a method?
It may be inaccurate to say that all the professors of Yanbei University's School of Mathematics are experts in the Chinese mathematics community.But these professors who could be drawn by Fan Zhenhua to eat together definitely deserve this praise.At this time, it is actually very simple to inquire about their inner feelings, just look at their expressions.

These professors who are really academic are not very good at covering up their emotions.Mainly because most professors don't bother to wear a mask for themselves.

It seems that many people like to comment that so-and-so has IQ but not EQ, but in fact, for people with real high IQ, EQ is only a relative concept. If they want, at least the breadth of knowledge and knowledge will definitely make ordinary people feel like a spring breeze. I just think it's fun to talk to the big guys.It's just that there are not many people who can enjoy this kind of treatment.

At this time, most of the professors in the School of Mathematics looked at each other in dismay.

It's not that I don't understand the professional terms Ning Yu said, but it is precisely because I understand it that I don't know how to speak.These fields are for an undergraduate... no, it should be said that a young man who has just finished his high school mathematics education can touch it?

It is no exaggeration to say that the things that Ning Zhi spit out, including Xin topology, norm fields, etc., even if a doctoral student wants to open a question, the doctoral supervisors here must carefully examine whether their students have a solid foundation. That talent to study these directions.After all, differential geometry and mathematical physics have always been one of the most difficult directions in mathematical research.

This difficulty is still two-way, it is difficult to understand, and it is equally difficult to calculate.

Of course, Ning Ruo felt the changes in the professors' gazes, and found that half of the professors' gazes were focused on Academician Fan, and the other half were focused on a young man with gold-rimmed glasses sitting diagonally across from him. of young professors.

This time someone spoke again: "Hey, Professor Fang, today Professor Liu went out to study and couldn't come, I remember that your recent proposal report was about Gromov-Witten invariants, so you can just communicate with our classmate Ning Ruo. "

Sure enough, the professor with the gold-rimmed eyes smiled slightly, and then said, "Since Professor Chen said so, why not let's discuss it, Ning? Let me tell you first, my recent research is [-]-dimensional, [-]-dimensional Dimensional and [-]-dimensional symplectic submanifolds, and proof of some transformation formulas when expanding the Gromov-Witten invariant during symplectic expansion surgery. Xiaoning should understand, right?"

Ning Yu nodded, and then asked, "Are you mainly using the degenerate formula to prove it?"

Fang Xu was slightly stunned, nodded, and said, "Well, for now, the most convenient way is the regression formula, right?"

Ning Yu nodded, then shook his head slightly, and said, "I can't say that completely, I can introduce you to a method, um... it's called Ning's segmentation method. It can be used in conjunction with the regression formula to make the proof process easier. Do more with less.”

"Uh..." Obviously Fang Xu didn't expect this answer, and he didn't know how to answer for a while.

However, Ning Yu had already looked at Fan Zhenhua and asked, "Do you have a pen and paper?"

"Yes, yes, yes." Fan Zhenhua replied immediately, then stood up and took out a stack of paper and pens from the briefcase on the box cabinet, returned to his seat and handed it to Ning Ruo.

Others watched this scene quite interestingly, especially Chen Yonggang.

As the president of the University of Physical Education, he actually did not have a very clear concept of Ning Wei's ability.He knew that "Annuals of Mathematics" was a very good publication, and it was difficult for ordinary mathematics professors to publish articles on it, but these were all results of Baidu.

He knew that Ning Ruo must be very powerful, but he didn't have an intuitive understanding of how powerful it was.At least not as deep as other professors who study mathematics on the scene, but this understanding is more intuitive now.For example, he didn't know what these people were talking about at all, he just felt ignorant.

Of course, this is also very normal. For 90.00% of people, the frontier research direction of modern mathematics is like a bible.Countless proper nouns have never been heard of by those who have not studied this field in depth.Many formulas are named after the inventors or to commemorate the contributions of these mathematicians to this research direction.

For example, the Gromov-Witten invariant in the two populations, the former Gromov refers to the former Wolf Prize winner Mikhail Gromov, and the latter witten is the Fields Medal winner Edward Witten.

But if you really want to explain the Gromov-Witten invariant, it is particularly complicated. The less accurate explanation of the once-classical Gromov-Witten invariant can be said to be the modulo space of the pseudo-holomorphic mapping from closed Riemann surfaces to symplectic manifolds. A special structure constructed.

This involves Riemannian geometry, symplectic geometry, etc. that make people tingle when they see it, which belongs to the category of academic research that most candidates in the open-book exam do not know where to copy.

But at this moment, Ning Yu wants to provide a new idea and mathematical tool for the professor who specializes in this direction...

At this time, Chen Yonggang really didn't know whether this new student of their size was ignorant and fearless, or whether his ability was far beyond his imagination.

But he is not in a hurry, anyway, he will know by looking at the expressions of these professors.

This is really interesting!

……

Chen Yonggang's judgment was obviously correct.

Just when Ning Ruo took the pen and paper, lifted the tablecloth, and began to immerse himself in writing, Fang Xu couldn't help but stand up from his position and walked directly behind Ning Ruo and stood there with Fan Zhenhua to watch. .

No way, Ning Yu's sentence "Ning's division method" obviously misunderstood him, thinking that Ning Yu's meaning was a mathematical tool or method created by him, so he named it after his own surname.

What kind of achievement is this?
How dare this little guy?

Fang Xu held back and did not refute it, it was already well-preserved.

Counting from his Ph.D., Fang Xu has been studying mathematics and physics for 12 years, and he is still not qualified to use his surname on a certain mathematical theory or tool!What the hell is this Ning's division method?

Obviously this is a misunderstanding.

Ning Ruo just truthfully demonstrated the method that March told him.The owner of March of that year happened to be surnamed Ning, what could he do?You can't change your surname just to avoid suspicion, right?

Of course, Ning Yu didn't think about it that much. He only remembered what March told him, showing himself properly would help get more resources.This is probably the appropriate display, right?After all, the opposite happened to talk about this topic, and he just followed the trend...

As a result, there were more and more professors behind Ning Zhi soon...

No way, not only Chen Yonggang can look at people's faces, when the professors saw Fang Xu's face became solemn, began to think deeply from time to time, and even began to scratch their heads unconsciously, they were more curious than the president of the University of Physical Education...

what?Can what this kid write really guide Lao Fang's research? !That's really strange.

This kind of thing must be seen first!
