Chapter 404: Join in

Chapter 404
October 9, the fourth day of the conference.
The reporting of more than one hundred academic reports has all been completed.
During this period, Cheng Nuo gave a total of 25 academic reports, covering seven fields of number theory, function theory, geometry, differentiation, applied mathematics, algebra, and topology.
From today onwards, there will be speeches, discussions and exchange activities in the remaining seven days until the end of the conference.
Most of the speakers participating in these activities are third-class mathematicians, and their importance is relatively small. Therefore, Cheng Nuo does not have to go to different venues without stopping.
More than 500 lectures, this number sounds like a lot, but most of the speakers are of the same level as the Professor Russell that Cheng Nuo met on the plane.
Of course, there will be some Philippine award winners who are in the first class and hold a small lecture.
After watching the Fields Medal Award Ceremony and more than 20 top academic reports in the world, Cheng Nuo's goal of entering the International Congress of Mathematicians has been mostly completed.
For the remaining seven days, Cheng Nuo planned to digest the content that he had not understood thoroughly when listening to the report before, while picking up a few lectures to listen to.
No matter how small a mosquito is, it is meat.
Although the results are definitely 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 worth listening to it.
In the room, Cheng Nuowang started with three or four pages of A4 paper printed lecture schedule, holding a pen to sketch on it.
"Fourth Mean Value of Generalized Fourth Gauss Sum"? Isn’t it just a computational problem with complex merits? It can be approved by the Mathematical Union. I don’t understand it!
"Reharmonization and Commutability of Hardy Space Toplitz Operators"? This is something from the last century, right? Anyone else turned it out and talked about it? Don't go, don't go.
"General Results of Accurate Asymptotic Convergence of NA Sequence Complete Matrix"? This is not bad. Professor Armand is the speaker, so I must go.
…………
After screening for a while, Cheng Nuo determined fifteen lectures that he must go to. As for the rest, let's do everything.
Anyway, he is a completely free man, and whatever hall he walks into is no matter what hall he walks into.
correct! Cheng Nuo patted his forehead and suddenly remembered something.
He remembered that it seemed that he had promised that Professor Russell that he would go and cheer him up.
What is the subject of his lecture?
Cheng Nuo took the lecture schedules and searched for Russell's name in the speaker column.
"Found it." Cheng Nuo's eyes fell on a line of the form.
Topic: "The Connection between Algebraic Geometry and Topology"
Speaker: Russell Slink
Lecture time: October 9 14:00~16:00
Such an ordinary topic is naturally not included in the 15 lectures that Cheng Nuo must listen to.
Cheng Nuo took a look at his lecture schedule. Well, the time does not conflict.
If this is the case, then listen to it, and don't lose anything anyway.
After finalizing the plan, Cheng Nuo changed into the waiter's clothes, carrying a tray, and pretending to deliver the meal, and came to today's first stop.
…………
"Good!"
During lunch, Cheng Nuo, who was gorging on a plate of steak in the room, couldn't help but groan.
A lecture in the morning made Cheng Nuo full again, but his only regret was that even though he had a lot of doubts in his mind, he did not dare to ask the mathematician who gave the lecture.
Before taking a nap, Cheng Nuo took advantage of the fact that most of the content was still in memory, and wrote down the knowledge gained in the morning in a notebook specially prepared for this mathematicians conference.
The original brand-new notebook, under the constant devastation of Cheng Nuo for several days, has been filled with two-thirds of the formula symbols.
At two o'clock in the afternoon, Cheng Nuo came to the small auditorium where Professor Russell lectured.
Cheng Nuo came here by the time point. It stands to reason that most of the mathematicians who intend to come to the lecture have already been there, but Cheng Nuo glanced over. In the small auditorium that can accommodate more than one hundred people, only a few are sitting. Only a dozen people.
In the last few rows, no one was seated at all.
"The popularity is a bit low, it's necessary for me to come here to cheer." Cheng Nuo muttered, sitting on the empty seats in the last row without any scruples.
This time, no one noticed him anymore.
Professor Russell, who was standing on the podium, looked at the three or two big cats and kittens below the stage, and his expression was a bit ugly.
Think of the lectures given by the Philippine bigwigs, the auditorium of four or five hundred people can be packed, but he can't be overstated.
But there is no way, the popularity and academic achievements of this group of top big brothers are far beyond the comparison of his little mathematician.
Quickly adjusted his emotions, Professor Russell squeezed a smile on his face and motioned to the young man beside him.
That young man, oh, is the Russell student Myron that 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 passionate tone, "First of all, I welcome you all to listen to my lecture in your busy schedule. The topic of my lecture is "The Connection between Algebraic Geometry and Topology" "."
"Before I talk about this, I must introduce a few concepts to everyone." Professor Russell clicked on a page of PPT, "The first one, the Riemann zata function!"
"As for what this function is, I don't need to go into too much detail. I will mainly introduce a few of its properties here, some of which are related to the topics I will talk about next."
"Ζ(s) can be analytically extended as a meromorphic function on the entire complex plane, 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), Γ is the 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). These zero points are called the trivial zero points of ζ(s). In addition, the non-trivial zero points of ζ(s) are all on the straight line Di(s)=1/2. ."
…………
Simply put, Russell calculates the number of rational points X(Fq^n) by studying the Zeta functions Zx(T) and ζx(s) of the algebraic cluster X defined on the finite field Fq, and then studies In the two cases of curve and abelian cluster, the properties satisfied by Zx(T).
This is not a novelty, but Professor Russell used a relatively new point of view to raise this question.
Professor Russell talked dryly on the stage, while Cheng Nuo, who came to join the audience, fell asleep with his head tilted in the middle of the lecture.
Not to blame Cheng Nuo, it is really boring what Professor Russell said.
On the stage, Professor Russell had finished the content of the PPT and looked forward to the twenty-odd people in the audience, looking forward to asking, "If you have any questions, you can raise your hands to ask questions. I must know everything."
There was silence.
Russell was extremely embarrassed, and said, "Is everyone really okay?"
Just one, at least one!
Professor Russell roared wildly in his heart~EbookFREE.me~ In the last row, Cheng Nuo woke up in a daze, stretched out, and yawned, "Comfortable!"
Cheng Nuo kept his limbs stretched out.
So in the eyes of Professor Russell on the stage, someone in the back row raised their hands, and also raised both hands.
Professor Russell's eyes lit up.
Raising two hands shows that the desire to ask questions is very strong!
Russell said with a smile, "The gentleman in the last row, can you stand up and tell your question?"
Cheng Nuo, who had just woke up, was confused.
What...what's this situation?
