061 Why don't I teach you a method
It may not be accurate to say that all the professors in the School of Mathematics at Yanbei University are great masters in Chinese mathematics. But these professors who can be invited by Fan Zhenhua to have dinner together definitely deserve this praise. At this time, we need to inquire
It's actually very simple to know their inner feelings, just look at their expressions.
There are actually not many professors who are really academics who are good at hiding their emotions. The main reason is that most professors don’t bother to wear a mask for themselves.

Just like many people like to comment on whether someone has IQ but not EQ, but in fact, for people with real high IQ, EQ is just a relative concept. If they are willing, at least the breadth of knowledge and knowledge will definitely make ordinary people feel like a spring breeze.
I just find it interesting to talk to the boss about anything. It’s just that not many people 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 Ning Zhe said, but it’s precisely because I understand that I don’t know how to speak. In these fields, an undergraduate... no, it should be said that he is a young man who has just received high school mathematics education.
Can it be involved?
It is no exaggeration to say that the things that Ning Ju spit out, including symplectic topology, gauge fields, etc., even if a doctoral student wants to propose a topic, the doctoral supervisors here must carefully examine whether their students have a solid foundation and whether they have any
Use your 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 equally difficult to calculate.
Of course, Ning Zi felt the change in the professors' gazes, and also found that almost half of the professors' gazes were focused on Academician Fan, and the other half were focused on the man sitting diagonally opposite him who wore gold-rimmed glasses and looked young.
of young professors.
This time someone spoke again: "Hey, Professor Fang, Professor Liu went out to study today and couldn't come. I remember that your recent thesis report was on the study of Gromov-Witten invariants. It's just a good time to communicate with our classmate Ning Ji.
"
Sure enough, the professor with gold-rimmed eyes smiled slightly, and then said: "Since Professor Chen said so, why don't we discuss it, Ning? Let me tell you first, what I am studying recently is 0-dimensional, 2
Dimension and 4-dimensional symplectic submanifolds, and proofs of some transformation formulas when expanding Gromov-Witten invariants during symplectic expansion surgery. Xiao Ning should understand, right?"
Ning Zi nodded, and then asked: "Are you mainly using the degeneracy formula to prove it?"
Fang Xu was slightly stunned, nodded and said: "Well, at present, the most convenient thing is the degradation formula, right?"
Ning Zi nodded, then shook his head slightly, and said: "I can't say that completely. I can introduce a method to you. Well...it's called Ning's segmentation method. It can be used in conjunction with the degeneracy formula to make the proof process easier.
Get twice the result with half the effort.”
"Um..." Obviously this answer was something Fang Xu didn't expect, and he didn't know how to answer it for a moment.
However, Ning Zi was already looking 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 pen from the briefcase on the box cabinet, returned to his seat and handed it to Ning Zi.
Others watched this scene with great interest, especially Chen Yonggang.
As the president of the National Sports University, he actually doesn't have a very clear idea of Ning Zi's abilities. He knows that "Annals of Mathematics" is a very good publication, and it is difficult for ordinary mathematics professors to publish articles in it, but these are all the results of Baidu.
.
He knew that Ning Zi must be very powerful, but he didn't have an intuitive understanding of how powerful he was. At least not as deep as other professors studying mathematics at the scene, but at this moment, the understanding was more intuitive. For example, he didn't know that these people were at all
What to talk about, I just feel unclear.
Of course, this is normal. For 90% of people, the cutting-edge research directions in modern mathematics are like a sacred book. There are countless proper nouns that people who have not studied this field in depth have never heard of. Many formulas
It is named after the inventor or to commemorate the contribution of these mathematicians to this research direction.
For example, the Gromov-Witten invariant mentioned by the two people, the former Gromov refers to the former Wolf Prize winner Mikhail Gromov, and the latter witten refers to 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 classic Gromov-Witten invariant can be said to be the modulus space of a pseudo-holomorphic mapping from a closed Riemann surface to a symplectic manifold.
A special structure constructed.
This involves Riemannian geometry, symplectic geometry, and other things that make one's head go numb just by looking at them. It falls into the category of academic research where most candidates for open-book exams don't know where to copy.
But now Ning Zi wants to provide a new idea and mathematical tool to professors who specialize in this direction...
At this time, Chen Yonggang really didn't know whether their new student from the University of Physical Education was ignorant and fearless, or whether he was really capable far beyond his imagination.
But he was not in a hurry, he would know it later by looking at the expressions of the professors.
This is really interesting!
…
Chen Yonggang's judgment was obviously correct.
Just when Ning Zi took the paper and pen, lifted the tablecloth, and began to immerse himself in writing, Fang Xu couldn't help but stood up from his seat, walked directly behind Ning Zi, and stood there with Fan Zhenhua to read.
.
He had no choice but to misunderstand Ning Zi's "Ning's division method". He thought that Ning Zi meant that this was a mathematical tool or method he created, so he named it after his own surname.
What the hell kind of achievement is this?
How dare this little guy?
Fang Xu showed good self-control by not opening his mouth to refute.
Counting from the beginning of his Ph.D., Fang Xu has been studying mathematical physics for twelve years, and he still has not the qualifications to name a certain mathematical theory or tool with his own surname! What the hell is this Ning's division method?
Obviously this is a misunderstanding.
Ning Zi just demonstrated the method that March told him truthfully. What could he do if the owner of March happened to be named Ning? He couldn't change his surname to avoid suspicion, right?
Of course, Ning Zi didn't actually think so much. He only remembered what Yue Yue told him. Showing yourself appropriately would help get more resources. This was probably a proper display, right? After all, the other person happened to be talking about it.
When this topic came up, he just followed the trend...
So, soon there were more and more professors behind Ning Zi...
There was no way, Chen Yonggang was not the only one who knew how to look at people's faces. When the professors saw that the expression on Fang Xu's face became solemn, he began to think deeply from time to time, and even began to scratch his head unconsciously, they were more curious than the president of the Physical Education University...
What? What this kid wrote can really point to Lao Fang’s research?! That’s really strange.
Chapter completed!
