It may not be accurate to say that the professors of the School of Mathematics of Yanbei University are all masters of the Chinese mathematics community. But these professors who can be brought to dinner by Fan Zhenhua are definitely worthy of this praise. At this time, to inquire into their inner feelings, it is actually very simple, just look at the expressions.

There are not many professors who are really academics who are good at hiding their emotions. Mainly, most professors disdain to put a mask on themselves.

It's like many people like to comment that so-and-so has IQ or not, but in fact, for real high-IQ people, EQ is just a relative concept, if they are willing, at least in terms of the breadth of knowledge and what they have seen and heard, it must make ordinary people feel like a spring breeze, and they only think that it is interesting to talk to the big guy. It's just that there aren't many people who can enjoy this kind of treatment.

At this time, most of the professors in the School of Mathematics were looking at each other.

It's not that I don't understand the professional terms that Ning Xiao said, but it is precisely because I understand that I don't know how to speak. These fields are an undergraduate ...... No, it should be said that a young person who has just completed his high school math education can be involved?

It is not an exaggeration to say that the things that Ning Xiao spit out of his mouth, including Xin topology, gauge field, etc., even if a doctoral student wants to start a topic, the doctoral supervisors here must carefully examine whether their students' foundation is solid and whether they have the talent to study these directions. After all, differential geometry and mathematical physics have always been one of the most difficult directions in mathematical research.

It's still a two-way street, it's hard to understand, and it's hard to calculate.

Of course, Ning Xiao felt the change in the professors' gazes, and found that almost half of the professors' eyes were focused on Academician Fan, and the other half was focused on a young professor with gold-rimmed glasses who was sitting diagonally opposite him and looked not very old.

This time, someone spoke again: "Hey, Professor Fang, Professor Liu went out to study today and couldn't come, I remember that your recent opening report was to study Gromov-Witten invariant, so you can communicate with our classmates Ning Xiao." ”

Sure enough, the professor with gold-rimmed eyes smiled slightly, and then said, "Since Professor Chen said so, why don't we discuss it?" First of all, I have recently studied 0-, 2-, and 4-dimensional symplecin manifolds to prove some of the transformation formulas for the expansion of the Gromov-Witten invariant during the Xinchang surgery. Xiao Ning should understand, right? ”

Ning Xiao nodded, and then asked, "Are you mainly using the degradation formula to prove it?" ”

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

Ning Xiao nodded, then shook his head slightly, and said, "I can't say that completely, I can introduce you to a method, huh...... It is called Ning's division method. It can be used in conjunction with the degradation formula to make the proof process twice as effective with half the effort. ”

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

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

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

Others watched the scene with great interest, especially Chen Yonggang.

As the president of the Sports University, he actually doesn't have a very clear idea of Ning Xiao's ability. He knew that the Annals of Mathematics was a very good publication, and it was difficult for ordinary mathematics professors to publish articles on it, but this was the result of Baidu.

He knew that Ning Xiao must be very powerful, but he didn't have an intuitive understanding of how powerful he was. At least not as deep as the other professors who study mathematics in the field, but at the moment this understanding is more intuitive. For example, he didn't know what these people were talking about, he just didn't know what he was talking about.

Of course, this is also very normal, and the frontier research direction of modern mathematics is like a book in heaven for 90% of people. There are countless proper nouns, and people who are not deeply involved in this field have not heard of it at all. Many formulas are named after the people who invented them or in honor of the contributions of these mathematicians to the direction of research.

For example, the Gromov-Witten in the two mouths is invariant, the Gromov in the front refers to the former Wolf Medal winner Mikhail Gromov, and the witten in the back is the Fields Medal winner Edward Witten.

But if we really want to explain the Gromov-Witten invariant, it is particularly complicated, and the once classical Gromov-Witten invariant is not so accurately explained, which can be said to be a special structure of the pseudo-holopure mapping modulo space construction from closed Riemannian surfaces to symplectic manifolds.

This involves Riemannian geometry, symptic geometry and other things that make people's scalp tingle when they see it, and belong to the kind of academic research category that the vast majority of candidates in the open-book exam do not know where to copy.

But at this moment, Ning Xiao wants to provide a new idea and mathematical tools for professors who specialize in this direction......

At this time, Chen Yonggang really didn't know if this new student of their body was ignorant and fearless, or if he was really far more capable than he imagined.

But he's not in a hurry, he'll see the looks of these professors anyway.

That's really interesting!

……

Chen Yonggang's judgment was obviously correct.

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

There was no way, Ning Xiao's sentence "Ning's Segmentation Method" obviously misunderstood him, thinking that Ning Xiao's meaning was a mathematical tool or method created by him, so he used his surname to name it.

What kind of achievement is this?

How dare this little guy?

Fang Xu couldn't help but didn't open his mouth to refute it, he was already very well cultivated.

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

Apparently this is a misunderstanding.

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

Of course, Ning Xiao didn't think about it so much, he only remembered what March told him in his mind, showing himself properly would help him get more resources. That's probably the proper display, right? After all, the other side happened to talk about this topic, and he just took advantage of the trend......

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

There is no way, not only Chen Yonggang can look at people's faces, when the professors saw that Fang Xu's face became solemn, they 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......

What's the matter? What this kid writes can really point to Lao Fang's research?! That's really weird.

This kind of thing must be seen first!
