Chapter 404

October 9, the fourth day of the conference.

More than 100 academic reports have been reported.

During this period, Cheng Nuo made 25 academic reports, involving seven fields: number theory, function theory, geometry, differential, applied mathematics, algebra and topology.

From today to the end of the conference, there will be lectures, discussions and exchanges in the remaining seven days.

Most of the speakers who participated in these activities were mathematicians of the third grade, and their importance was relatively small. Therefore, Cheng Nuo did not have to go back and forth to different venues without stopping.

There are more than 500 lectures, which sounds like a lot, but most of the speakers are about the same level as the professor Russell that Cheng Nuo met on the plane.

Of course, there will also be a first-class Philippine prize winners who have nothing to do and hold a small lecture.

After watching the fields prize presentation ceremony and more than 20 academic reports from the world's top, Cheng's goal of getting involved in the International Conference of mathematicians has been completed.

For the rest of the seven days, Cheng Nuo plans to pick up a few lectures while digesting what he had not yet understood.

A mosquito is meat, no matter how small it is.

Although the harvest is certainly not as good as the previous academic reports, as long as you can master a mathematical method or a way of thinking about problems, it is not in vain to listen.

In the room, Cheng Nuo looks at the lecture schedule printed on A4 paper in his hand and draws with a pen.

Quartic mean of generalized quartic Gauss sums? Isn't it a calculation problem with complex advantages? It can be approved by the mathematical alliance. I don't understand it!

Commutativity of toplitz operators in biharmonic Hardy spaces? This is something of the last century, is it? Is there anyone else who will turn it over? No, No.

General results on exact asymptotics of convergence for complete matrices of NA sequences? This is good. The speaker is Professor Armand, so we must go there.

…………

After screening for a while, Cheng Nuo decided to attend 15 lectures that he must attend. As for the rest, he would follow suit.

Anyway, he is a completely free man. He can walk into any auditorium.

By the way! Cheng Nuo patted his forehead and suddenly remembered something.

He remembered as if he had promised that Professor Russell would go and cheer him up.

What was the theme of his lecture?

Cheng Nuo took the lecture schedules and searched Russell's name in the speaker's column.

"Found it." Cheng Nuo's eyes fall on one line of the table.

Topic: the connection between algebraic geometry and topology

Speaker: Russell slinkle

lecture time: October 9, 14:00 ~ 16:00

such a common topic is naturally not included in the 15 lectures that Cheng Nuo must listen to.

Cheng Nuo looked at his lecture schedule. Well, time doesn't conflict.

In that case, go and listen to it. It won't lose anything anyway.

After finalizing the plan, Cheng Nuo changed into a waiter's clothes, carried a tray, and pretended to deliver the meal to the first stop of today.

…………

"Cool!"

At lunch time, with a plate of steak in the room, Cheng Nuo can't help groaning.

A lecture in the morning made Cheng Nuo full of fruits, but the only pity was that even though he had a lot of doubts in his heart, he did not dare to ask the mathematician who gave the lecture.

When he didn't come to take a nap, Cheng Nuo took advantage of most of the contents and wrote down the knowledge gained in the morning in a notebook specially prepared for the meeting of mathematicians.

The original brand-new notebook, under the constant destruction of Cheng Nuo for several days, has been filled with two-thirds of a large number of formula symbols.

At two o'clock in the afternoon, Cheng Nuo comes to the small auditorium where Professor Russell talks.

Cheng Nuo came at a certain point in time. Normally speaking, most mathematicians who would like to attend the lecture have already arrived. However, at a glance, there are only 20 or so people sitting in the small auditorium which can accommodate more than 100 people.

In the last few rows, no one was seated at all.

"The popularity is a little low. It's necessary for me to come to the stage." Cheng Nuo murmured in a low voice and sat on the empty seat in the last row without any scruples.

This time, no one noticed.

Professor Russell, standing on the stage, looked at the big cats and two kittens. His face was also a little ugly.

If you think about the lectures given by the big Fei prize winners, the auditorium of four or five hundred people will be full of seats, but you can't miss him.

But there is no way, the popularity and academic achievements of this group of top men are far beyond the comparison of his little mathematicians.

Quickly adjusted his mood, Professor Russell squeezed out a smile on his face and motioned to the youth on the side.The young man, oh, is the Russell student Myron that Cheng Nuo met on the plane.

Myron adjusted the projector and turned on the PPT for the lecture.

Then, Professor Russell began to speak with no passion. "First of all, welcome to my lecture in your busy schedule. The theme of my speech is the connection between algebraic geometry and topology."

"Before I talk about this, I have to introduce you to a few concepts." Professor Russell opened a page of PPT, "first, Riemann Zata function!"

"I don't have to go into too much detail about what this function is. I'm going to focus on a few properties of this function, some of which are related to my next topic."

"ζ (s) is analytically extended to a meromorphic function in the whole complex plane, which has only a single pole at S = 1. Consider the complete ζ (s) of ζ (s): = π ^ (- S2) Γ (S2) ζ (s), where Γ is a gamma function, then ζ (s) satisfies the functional equation ζ (s) = ζ (1-s). "

"At the same time, every negative even number is the zero point of ζ (s), which is called the trivial zeros of ζ (s). In addition, the nontrivial zeros of ζ (s) are all on the line di (s) = 12."

…………

In short, Russell calculates the number of rational points | x (FQ ^ n) | by studying the zeta functions ZX (T) and ζ x (s) of algebraic variety x defined on the finite field FQ, and then studies the properties of ZX (T) in the case of curves and Abelian clusters.

It's nothing new, but Professor Russell uses a relatively new point of view to raise the issue.

On the stage, Professor Russell spoke dryly, while under the stage, Cheng Nuo, who came to support the audience, fell asleep with his head tilted in the middle of the lecture.

No blame for Cheng Nuo. It's really what Professor Russell said that was too boring.

On the stage, Professor Russell has finished the content of the PPT, full of expectation, looking at the 20 odd people under the stage, expecting to ask, "if you have any questions, you can raise your hands and ask questions. I will certainly know everything."

There was silence.

Russell was very embarrassed and said, "are you all right?"

Just one, at least one!

Professor Russell roared in his heart.

In the last row, Cheng Nuo wakes up in a daze, stretches his body and yawns, "comfortable!"

Cheng Nuo remained in a stretched posture.

So in the eyes of Professor Russell on the stage, there were hands raised in the back row, and two hands were also raised.

Professor Russell's eyes brightened.

Raise two hands, the desire that wants to ask a question is very strong!

Russell said with a smile, "can the gentleman in the last row stand up and say your question?"

Cheng Nuo, who just woke up, was in a daze.

What What's the situation?
