Chapter 457

Cheng Nuo stood on the podium and looked at the group of classmates below who were on average one or two years older than him, and a strange smile flashed on the corner of his mouth.

The theme of Cheng Nuo's lecture is Jacopy's theorem, so he didn't say anything too much, and simply said hello to his classmates and went straight to the point.

“...... Before the Jacobian conjecture was proven, there were three directions of exploration that were recognized by the mathematical community. Cheng Nuo held up a finger and said while walking around the podium, "The first is the K theory method proposed by Case Booker in the nineties of the last century, which uses the order of the polynomial and the dimension of space to exchange the coefficients of the polynomial to obtain a dimension that can be arbitrarily large in space......"

"The second is that Professor Ian of Princeton University ...... five years ago by studying the two curves f=0,g=0 on the domain k and the curves F(x,f,g)=0 on the domain k(X) to obtain their singularity at infinity."

“...... The third is the Keller mapping local biprojection method that started the manifold at the beginning of this century. And I used this method to successfully prove the Jacobian conjecture. Students must be curious about why I chose this method among the three methods, and below, I will explain the specific content of Jacobi's theorem to you......"

Next, Cheng Nuo talked about the specific proof process of Jacoby's conjecture.

However, with a research cycle of half a year and a proof paper of more than 50 pages, it can be explained in detail in just over an hour.

Therefore, Cheng Nuo just picked out some key points and difficulties to tell, and as for those parts that are not very difficult, Cheng Nuo regarded them as if everyone already understood, and directly skipped them in a few short sentences.

As a result, Cheng Nuo on the stage naturally spoke with relish, and gradually entered a better situation. And the students in the audience became more and more confused the more they listened.

They can't say that Cheng Nuo didn't speak well, some difficult points, Cheng Nuo did explain them clearly.

But the point is, Cheng Nuo seems to be ...... Look too highly of them!

Originally, it was a good thing to be looked up to. But at this time, everyone did not look happy at all.

Cheng Nuo brought a lot of specific content in a simple sentence or two, saying "As a top student at MIT, everyone should know this point, so I won't expand on it" and followed the following content, which made them very hurt!

But it's not good for them to remind Cheng Nuo directly and let him speak in detail.

It's a shame to be without him!

Once he spoke, it was really an admission that there was a gaping gap between them and Cheng Nuo.

It's one thing to be true, it's another to admit it yourself.

So everyone was silent, and they didn't know how to pretend to understand and listened to Cheng Nuo's entire lecture.

“...... Here, using the five formulas mentioned above, all the scattering data are put together, and in this way, the Jacobi conjecture is proved!" Cheng Nuo finished speaking, threw the chalk head on the lecture, turned around, and looked at the audience with a smile on the lectern with both hands.

Silence, silence for several seconds......

The students in the audience were expressionless and frowning, not knowing what they were thinking.

Applause!

Cheng Nuo saw that everyone had not reacted for a long time, and he was anxious.

He raised his eyebrows, met the eyes of a Chinese student, and winked at him frantically.

The Chinese student hesitated, and when he saw Cheng Nuo's eyes suddenly become sharp, he immediately applauded.

Papapapa~~

Others also reflected and reluctantly snapped.

A satisfied smile appeared on the corner of Cheng Nuo's mouth.

He tucked the cuffs of his shirt and said with a smile, "The following is the question session, everyone can say any questions." The content can have nothing to do with this lecture, any life, any study. ”

"But don't ask about the emotional state, I already have a girlfriend, and you don't have a chance!"

As soon as Cheng Nuo's words came out, he couldn't help but cause several girls to laugh, and the atmosphere at the scene suddenly became a lot more relaxed.

Cheng ...... Professor Cheng, I heard that you won the Wiblen Prize for your research on Jacobi's theorem some time ago, becoming the youngest laureate in history, how did you feel at that time?" asked a male student, standing up.

"If you're not used to calling me a professor, you can just call me a senior. Cheng Nuo smiled and waved his hand, motioning for the male classmate to sit first.

"I was definitely happy at the time, but I don't feel anything anymore. Although the Wiblen Prize is famous in the field of geometry, there are more than one or two awards higher than it in the whole field of mathematics, and there is still a long way to go, and it is not yet time for me to be complacent. ”

"Senior, do you mean that your goal is to win something higher than the Wiblen Prize, the Wolf Medal, or the Fields Medal?"

"The goal for a short time is the Fields Medal, after all, the Wolf Medal will not be won until at least after the age of forty. Cheng Nuo shrugged.

"Senior, you are so confident that you will win the Fields Medal, you know, no Chinese has won the award yet?"

Cheng Nuo's cold gaze swept over the boy who asked the question, "Then why can't I be the first!"

The crowd was in an uproar.

Cheng Nuo's words are too confident!

However, the crowd didn't intend to continue the question, and another blonde girl stood up and asked softly, "Senior, some people say that you rely on luck to prove Jacopy's conjecture, and a large part of it depends on luck, what do you think about this?"

Cheng Nuo smiled faintly, "We have a saying in Huaguo, which says that opportunities are for those who are prepared, and luck is for those who seize opportunities." ”

"Senior, I want to ......"

............

At the end of the two-hour lecture, although everyone was a little unpleasant, it was relatively perfect.

For the next period of time, Cheng Nuo continued to stay at school.

The small cubicle in Professor Fresnel's office has been given to Cheng Nuo, and he is now the second-in-command of this small-scale office.

Professor Fresnel knew that Cheng Nuo needed a period of rest, so he did not assign too tedious tasks to Cheng Nuo. Just let Cheng Nuo take a few of his assistants to get a few new outsourcing projects.

It wasn't until a month later that Cheng Nuo received a new assignment.

Cheng Nuo was not approached by Cheng Nuo's immediate supervisor, Professor Fresnel, but by a deputy director of the Massachusetts Institute of Technology's Institute of Mathematics.

"Mr. Jill, do you have any new projects for me?" Cheng Nuo came up and asked straight to the point.

Mr. Jill nodded and said, "There is indeed a new task that needs to trouble Professor Cheng. ”

Cheng Nuo stretched out his hand and gestured, "Please speak." ”

"This project is not a task assigned by the school, but a cleansing project of geometric conjectures led by the Clay Institute. ”

"Purge plan?" Cheng Nuo frowned.

"Yes, to be honest, this purge plan is still inseparable from Professor Cheng. ”
