Chapter 380

It was none other than Cheng Nuo, who had listened carefully to the lecture throughout the whole process.

So countless eyes looked in the direction where Cheng Nuo was.

And Tan Weiwei, who was sitting next to Cheng Nuo, was naturally noticed by everyone.

For Cheng Nuo, of course, they are strangers. But Tan is slightly different.

Most of the people attending this lecture today are students from MIT and Harvard University, and Tan Weiwei, as a third-year student in the Department of Mathematics, looks up and doesn't look down, and naturally there are many people who know her.

can sit next to the man who raised his hand, and both of them have the faces of Chinese people, and the two of them are eighty percent of them coming together.

It's just that they don't have any impression of that man, the man who looks much younger than them.

At this point, the people who were disturbed by Cheng Nuo's sudden raising of their hands were not so anxious to leave, holding their arms one by one, staring at Cheng Nuo to see what he could say.

On the stage, Yamashita Zhenwei was also stunned.

I thought it was just a routine question, but I didn't expect someone to raise their hand.

A kind smile appeared on Yamashita Zhenwei's face, and he stretched out his hand to the direction where Cheng Nuo was, "This classmate, come, tell me your confusion!"

At the same time, Yamashita really didn't look like a master, and looked at the audience indifferently. It looks like you're making things difficult for me despite the question.

At the age of nineteen, he entered Ueda Shinichi and followed his teacher for more than ten years, but he only thoroughly understood Ueda Shinichi's cosmic Teichmuller theory.

But this is only one or two of them, which can make him proud of the rest of the country and a leader in his generation.

If you look at the leopard, you can see how bad Ueda Shinichi has created this set of mathematical tools.

Yamashita really didn't dare to say that in today's world, except for his teacher Ueda Shinichi, no one would surpass him in the understanding of the intercosmic Teichmuller theory by more than five fingers.

Therefore, he is not afraid of any difficulties from Cheng Nuo.

"Cheng Nuo, are you serious?" Seeing countless eyes converging on the two of them, Tan Wei couldn't help tugging at the hem of Cheng Nuo's clothes and asked in a low voice.

Cheng Nuo smiled and said in a low voice, "Of course it's serious." I do have a little doubt, and I hope to get answered. ”

After speaking, Cheng Nuo took the microphone from the front row, cleared his throat, and said, "I do have a question, and I hope that Mr. Yamashita will give me advice." ”

"I remember that Mr. Yamashita said just now that in the exposition of Teichmuller's theory of the universe, a considerable amount of space is devoted to the problem of inertial groups and Profen-Deen torsion in the hyperbolic Far Abelian geometry. ”

"Yes, that's good. Yamashita nodded in disapproval.

Cheng Nuo immediately smiled, "Then my question is, if you set Σ now?" Primes is a complex number of empty subsets, and the PSC-type half-graph can be thought of as a slightly modified Galis classification formula for an "infinite group graph", which should be associated with a curve that takes into account the stability of points. So I want to ask, if you determine this curve?"

After the question was finished, Cheng Nuo raised his eyes, and his gaze fell on the serious Yamashita Zhenwei on the stage.

This student's question is very tricky!

Based on Cheng Nuo's question alone, Yamashita really didn't judge that the student understood at least ninety percent of what he just said.

I don't know if he's a demon from MIT or Harvard!

Cheng Nuo's question is tricky, but it is not off topic at all.

"Let me think about it. Yamashita frowned in contemplation, and then took out scratch paper and pen directly from his briefcase.

The group of students below were all surprised when they saw that Yamashita really did not act like this, and they all looked at each other again.

Stumped!

A student with no name stumped the student of Ueda Shinichi as soon as he opened his mouth!

You know, that's a mathematician who has been immersed in the theory of the universe for more than ten years!

The atmosphere in the small hall became silent little by little.

The students didn't have the idea of leaving in a hurry, but looked at the stage one by one, hoping that Yamashita really didn't give an answer sooner.

But fifteen minutes later, Yamashita finished writing and drawing on the paper, turning his head and writing a series of formulas on the blackboard behind him.

【(U，x)→H^2(U，U\{x}； Z)

Aut^|grph|（g)∈Aut(g)

Dehn(g)={α∈Aut|grph|（g)|αg|v=idg|v

?（＾?＾●）?? （●′?｀）?

..................】

A dozen lines of formulas were written out in one go.

He wiped the sweat on his forehead with his cuffs, looked at Cheng Nuo's calm eyes, and asked, "Do you understand?"

Cheng Nuo stared at the blackboard, was silent for a few seconds, and then bowed his head, "I understand." ”

is indeed worthy of being a disciple of Ueda Shinichi, and as soon as he read the formula he wrote, he gave Cheng Nuo a sense of sudden enlightenment.

Yamashita really didn't exhale lightly.

It's finally messed up. He was really worried that if he couldn't answer Cheng Nuo's question, it would be a shame.

"Then this classmate, when the question is finished, you can sit down. Yamashita really did not gesture to Cheng Nuo with his hand, "Are there any other students and questions, if not, our academic lecture will be over, the next lecture will be held in New York, and the time will be next Friday, you can publicize it." ”

"Wait a minute!" Yamashita had just finished speaking, when a shout came from below.

Looking in the direction from which the voice came, it was Cheng Nuo's familiar face.

Yamashita really smiled bitterly, "Classmate, aren't you done with your question, what's the matter?"

Cheng Nuo smiled at the corner of his mouth, "Mr. Yamashita, who said that my question is finished?"

"Just now, it was just the first question I wanted to ask, and the student has another doubt, I wonder if Mr. Yamashita can answer it again?"

The corners of Yamashita Zhenwei's mouth twitched, and he had to bite the bullet and say, "I'm happy." ”

Actually, this second question is related to the first question. Previously, Mr. Yamashita solved the equation for this stable curve, so the student would like to ask, since after the equation is determined, there will inevitably be a Proite group behind it, plus an isomorphic curve. So how to express, on a more conceptual level, the form of a finite hyperbolic topological surface of a PSC-type half-graph?" Cheng Nuo said in an unhurried tone.

Yamashita really frowned.

Where did this student come from, and why did he keep asking such tricky questions?

"Let me groan again. ”

No way, take out the big baby scratch paper, forget it!

Ten minutes, twenty minutes, thirty minutes......

Seeing that more than half an hour had passed in a hurry, the group of students below had gradually raised the volume and became extremely noisy.

Cheng Nuo sat on the seat as if he was sitting on Mount Tai, chatting with Tan in a whisper.

Finally, there was really no movement on the stage.

He brushed off more than ten pages of scratch paper off the lecture table and said in a dejected voice, "I, I can't answer!"
