Chapter 404

October 9th, the fourth day of the conference.

The reporting work of more than 100 academic reports has been completed.

During this period, Cheng Nuo took a total of twenty-five academic reports, covering seven fields: number theory, function theory, geometry, differentiality, applied mathematics, algebra, and topology.

From today onwards and until the remaining seven days of the conference end, speeches, discussions and exchange activities will be arranged.

Most of the speakers participating in these activities are third-level mathematicians, and their importance is relatively less, so Cheng Nuo does not have to go to different venues without stopping to run back and forth.

There were more than 500 lectures, and this number sounded a lot, but most of the speakers were about the same level as Professor Russell that Cheng Nuo met on the plane.

Of course, there will also be tycoons in the first grade of the Philippines Awards who are idle and hold a small lecture.

After watching the Fields Medal and taking advantage of more than 20 academic reports from the top of the world, Cheng Nuo's purpose of infiltrating the International Mathematician Conference has been accomplished most of the time.

For the remaining seven days, Cheng Nuo planned to take a few lectures to listen to while digesting the content that he had not understood thoroughly when listening to the report.

No matter how small a mosquito is, it is still meat.

Although the harvest is definitely not as good as the previous academic reports, as long as you can master a mathematical method or a way to think about problems, it will be in vain.

In the room, Cheng Nuo looked at the lecture schedule printed on three or four pages a4 paper in his hand, and took a pen to draw on it.

"Four times mean of generalized four gauss sum"? Isn't it just a computational problem with complex advantages? It can be reviewed and approved by the Mathematics Alliance. I can't understand it or understand it!

"Re-adjust the exchangeability of toplitz operators in hardy space"? This is something from the last century, and some people have come up with it and say it? Don't go, don't go.

"General results of accurate graduality of the convergence of the complete matrix of the na sequence"? This is good, Professor Armand is the speaker, so we must go even more.

…………

After screening for a while, Cheng Nuo determined fifteen lectures that he must attend. As for the rest, it should be completely free.

Anyway, he is a completely free man, and he will be considered an auditorium if he walks into it.

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

He remembered that it seemed that he had promised Professor Russell to support him.

What is the subject of his lecture?

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

"Finally found." Cheng Nuo's eyes fell on a line in the table.

Topic: "The Link between Algebraic Geometry and Topology"

Speaker: Russell Slingke

Lecture time: October 9th 14:00~16:00

Such an ordinary topic is naturally not included in the fifteen lectures that Cheng Nuo must listen to.

Cheng Nuo looked at his lecture schedule, well, time does not conflict.

Since that's the case, then listen, no loss anyway.

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

…………

"It's so cool!"

During lunch, Cheng Nuo, who was swallowing a plate of steak in the room, couldn't help but moan.

A lecture in the morning gave Cheng Nuo a lot of gains, but the only regret was that even though he had a lot of doubts in his heart, he did not dare to come to the mathematician who gave the speech to ask.

Before he had time to take a nap, Cheng Nuo took advantage of the fact that most of the content still had memories and wrote the knowledge he gained in the morning in a notebook specially prepared for this mathematician conference.

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

At two o'clock in the afternoon, Cheng Nuo came to the small auditorium where Professor Russell gave a lecture.

Cheng Nuo came at the time point. Logically speaking, most mathematicians who were interested in listening to lectures had already arrived, but Cheng Nuo glanced at it and found that there were only a few more than twenty people sitting in the small auditorium that could accommodate more than one hundred people.

In the back rows, no one sat down.

"The popularity is a bit low, so it is necessary for me to come and support me." Cheng Nuo muttered in a low voice, sitting in the empty seat in the last row without any scruples.

This time, no one noticed himself.

Professor Russell, standing on the podium, looked at the three or two big cats below, and his face looked a little ugly.

I think the lectures of those Philippine Award winners can be filled with four or five hundred people, but it is not an exaggeration to have a place for him.

But there is no way, the popularity and academic achievements of these top tycoons are far from comparable to his little mathematician.

After quickly adjusting his emotions, Professor Russell squeezed out a smile on his face and signaled to the young man beside him.

That young man, oh, is Russell's student Myron, who Cheng Nuo met on the plane.

Myron adjusted the projector and opened the ppt for the lecture.

Then, I heard Professor Russell speak in a passionless tone, "First of all, welcome to listen to my lecture in a busy manner. The theme of my speech is "The Connection of Algebraic Geometry and Topology."

"Before I'll tell you about this, I have to introduce some concepts to you." Professor Russell clicked on a page of ppt, "The first one is Riemann zata function!"

"I don't need to elaborate on what this function is. I will mainly introduce several properties of it and several properties related to the topic I will talk about next."

"ζ(s) can analytically extend into a subpure function on the entire complex plane, and it only has a single pole at s=1. Consider the complete ζ(s) of ζ(s): =π^(-s/2)Γ(s/2)ζ(s), and Γ is a gamma function, then ζ(s) satisfies the function equation ζ(s)=ζ(1-s)."

"At the same time, every negative even number is the zero point of ζ(s), which are called the ordinary zero point of ζ(s). In addition, the non-trivial zero point of ζ(s) is all on the straight line di(s)=1/2."

…………

Simply put, Russell calculates the number of rational points by studying the zeta functions zx(t) and ζx(s) of algebraic cluster x defined on the finite domain fq, and then studies the properties satisfying by zx(t) in the two cases of curves and Abel clusters.

This is not a novel thing, but Professor Russell used a relatively novel point of view to raise this question.

Professor Russell spoke dryly on the stage, while Cheng Nuo, who came to support the stage, tilted his head and fell asleep halfway through the lecture.

It’s not that Cheng Nuo is really too boring for what Professor Russell said.

On the stage, Professor Russell had finished speaking what PPT said, looking at the twenty people below the stage with anticipation, looking forward to asking, "If you have any questions, you can raise your hand to ask questions, I will definitely tell you everything."

It's quiet.

Russell was extremely embarrassed and said embarrassedly, "Are you really okay?"

Just one, at least one!

Professor Russell yelled in his heart.

In the last row, Cheng Nuo woke up in a daze, stretched his body, and yawned a big yawn, "Comfortable!"

Cheng Nuo kept his limbs stretched.

So in Professor Russell's eyes on the stage, someone raised his hands in the back row, and even raised his hands.

Professor Russell's eyes lit up.

Raising two hands means that the desire to ask questions is very strong!

Russell smiled and said, "Can the gentleman in the last row stand up and tell your question?"

Cheng Nuo, who had just woken up, was confused.

What...what is this situation?
