Chapter 380: I can't answer!

Chapter 380
It was not someone else who raised his hand, it was Cheng Nuo who listened carefully to this lecture.
As a result, countless gazes swept toward Cheng Nuo's direction.
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 participants in this lecture today are students from the Massachusetts Institute of Technology and Harvard University, and Tan Weiwei, as a graduate student of the Mathematics Department, sees her without looking up, and many people know her naturally.
Being able to sit next to the man who raised his hand, and both of them are Chinese faces, 80% of the two came together.
It's just that they don't have any impression of that man, who looks much younger than them.
At this point, everyone who was disturbed by Cheng Nuo's sudden raising of their hands went away in a less anxious manner, holding their arms one by one, staring at Cheng Nuo to see what he could say.
On the stage, Yamashita Zhenwei was also taken aback.
I thought it was just a routine question, but I didn't expect someone to raise their hand.
A gentle smile appeared on Yamashita Zhenwei's face, and he gestured to Cheng Nuo where he was, "This classmate, come, tell me your confusion!"
At the same time, Yamashita really didn't put on the appearance of a master, looking at the stage lightly. It looks like you even make things difficult for me.
At the beginning, when he was 19 years old, he went to Ueda Shinichi and followed his teacher for more than ten years. Only after he had fully understood Ueda Shinichi's intercosmic Teihmuller theory.
But this is only one or two of these, which can make him stand out from the crowd in the country, and he is the best in the same generation.
By looking at the leopard, you can see how bad the mathematical tools created by Ueda Shinichi are.
Yamashita really did not dare to say that in today's world, with the exception of his teacher Ueda Shinichi, there are no more than five fingers that surpass him in the understanding of the universe's Teihmuller theory.
Therefore, he is not afraid of any difficulties Cheng Nuo makes.
"Cheng Nuo, are you serious?" Seeing countless eyes gathered on the two of them, Tan Weiwei couldn't help but grabbed Cheng Nuo's clothes and asked in a low voice.
Cheng Nuo smiled and whispered, "Of course I am serious. I do have some doubts, and I hope to get an answer."
After finishing speaking, Cheng Nuo took the microphone from the front row, cleared his throat, and said, "I do have a question, and I hope Mr. Yamashita will give me advice."
"I remember that Mr. Yamashita just said that in the explanation of the intercosmic Teihmuller theory, a considerable amount of space was devoted to the inertial group and the Profin-Dern torsion problem in the far Abelian geometry composed of hyperbolas."
"Yes, not bad." Yamashita nodded without approval.
Cheng Nuo immediately smiled, "Then my question is, if Σ?Primes is now a complex number of an empty subset, then the PSC-type semigraph can be regarded as a slightly modified Galis classification of the "infinite group graph". Formula, it should be associated with a curve that takes into account point stability. Then I would like to ask, if this curve is determined?"
After the question was finished, Cheng Nuo raised his eyes, and his gaze fell on Zhenwei under the solemn mountain on the stage.
This student’s problem is very difficult!
Based on the question asked by Cheng Nuo, Yamashita really didn't make a decision. The student understood at least 90% of what he said just now.
I don't know if he is from MIT or Harvard University!
Cheng Nuo's question is very difficult, but it is not at all partial.
"Let me think about it." Yamashita really didn't frown in thought, and then took out the draft paper and pen directly from the briefcase.
And the group of students below, seeing that Yamashita really didn't act like this, looked at each other again, all surprised.
Stuck!
An unknown student, as soon as he spoke, he stumped the student of Shinichi Ueda!
You know, that is a mathematician who has been immersed in the Teihmuller theory of the universe for more than ten years!
The atmosphere in the small auditorium became silent a little bit.
The students were not in a hurry to leave, but looked at the stage one by one, hoping that Yamashita could not give the answer as soon as possible.
But after a full fifteen minutes, Yamashita really finished writing and drawing on the paper, turned his head and wrote 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∈Autgrph(g)αgv=idgv
?(＾?＾●)?? (●′?｀)?
………………】
A dozen lines of formulas were written by Yamashita Zhenwei in one go.
He wiped the sweat from his forehead with his cuff, looked at Cheng Nuo's calm eyes, and asked, "Do you understand?"
Cheng Nuo stared at the blackboard, was silent for a few seconds, then nodded, "Understand."
He was indeed a disciple of Ueda Shinichi. Once he read the formula he wrote, it gave Cheng Nuo a sense of realization.
Yamashita really did not breathe lightly.
Finally passed. He was really worried that he could not answer Cheng Nuo's question, which would be a shame.
"Then this classmate, after asking the question, you can sit down." Yamashita really did not gesture to Cheng Nuo with his hand, "Are there any other students who have questions? If not, our academic lecture will end. The lecture will be held in New York. It will be next Friday, so you can promote it."
"Wait a minute!" Just as Yamashita finished speaking, there was such a shout from below.
Looking in the direction of the sound, it was Cheng Nuo's familiar face.
Yamashita really didn't smile bitterly, "Classmate, haven't you finished asking your question, what else is there?"
Cheng Nuo smiled, "Mr. Yamashita, who said, I have finished asking my question?"
"Just now, it was just the first question I wanted to ask. The student has another doubt. I wonder if Mr. Yamashita can answer it again?"
Yamashita really twitched the corners of his mouth, and had to bite the bullet and said, "I'm so happy."
"Actually, this second question is related to the first question. Before, Mr. Yamashita solved the equation of the stable curve. Then the students would like to ask, since the equation is determined, the Proite group will inevitably appear, plus an isomorphic one. Curve ~EbookFREE.me~ So how to express, at a more conceptual level, the form of a finite hyperbolic topological surface of a PSC semigraph?" Cheng Nuo said in a hurry.
Yamashita really didn't frown.
This student, where did he come out, and why he always asked such tough questions.
"Let me ponder again."
No way, take out the big baby draft paper, forget it!
Ten minutes, twenty minutes, thirty minutes...
Seeing that more than half an hour passed in a hurry, the discussion of the group of students below who were originally whispered gradually increased in volume and became extremely noisy.
Cheng Nuo was sitting on the seat like Mount Tai, chatting quietly with Tan Wei.
Finally, there was really no action under the mountain on the stage.
He flicked more than ten pages of draft paper off the lecture table and let out a sigh, "I can't answer!"
