The academic seminar lasted for three days.

The venue where Liu Yichen was present was dominated by experts in the field of number theory.

Liu Yichen has two reports to give, one is about the distribution of Mersenne prime numbers, and the other is about the research on the hail conjecture.

These two lectures are both popular at the Chinese Mathematicians Conference, attracting many scholars in the field of number theory or research on number theory to attend the lectures, as well as undergraduates, graduate students, doctoral students or students from the Department of Mathematics of Ludao University.

Other mathematics enthusiasts came here because of his reputation, and the entire lecture hall was full. Those who had no room to sit had to stand.

There were several blackboards placed on the podium. Liu Yichen wrote down equations one by one on the blackboard while explaining. Unlike his previous overseas explanations, where the speech was fast and the progress was fast, Liu Yichen did not speak very fast this time, and his speaking speed was deliberately slowed down.

Therefore, after a report meeting, eight small blackboards were filled with rows of calculation formulas. Although it was only April and had not yet entered May, Liu Yichen's forehead was already covered with sweat. He was wearing casual short-sleeves and holding a piece of chalk in his hand.

, said confidently: "To sum up, when 2^(2^n)

As time goes by, the mathematical community has now reached a unified opinion on his 'Zhou's conjecture'. Major mathematical research institutions and universities have completed his thesis demonstrations. Therefore, this year, the World Mathematical Union will publish 'Zhou's conjecture'.

The four conjectures' were corrected into the theorem, and the theorem is the 'Zhou-Liu Theorem', which is one of the few mathematical theorems named after China.

The entire lecture hall burst into warm applause.

"So handsome. It turns out that mathematicians are not stupid. They can also be very handsome. It's so cool. He took a piece of chalk and wrote on the blackboard. It's so cool!"

"I am a scumbag with a bachelor's degree in mathematics, but I can actually understand what he is saying. This is so awesome. I am worthy of being a master of number theory!"

"The most handsome guy in mathematics, the best math guy in the handsome guy world, is there anyone?"

"It's so charming. At this moment, I felt the wisdom of mathematics. It turns out that mathematics is so charming."

"As expected of a mathematical genius, he is actually able to write so many calculations. These calculations are like ghost drawings."

"I have decided that I also want to find a boyfriend who majors in mathematics. Having such a boyfriend who majors in mathematics must be very respectable."

"...."

The students at Ludao University were talking excitedly in low voices. Almost all of them were hearing this kind of mathematics report for the first time. At this moment, they were shocked. As long as they are not particularly bad at mathematics, they are basically more or less.

Can understand some things.

There was a little time left for Liu Yichen to answer some questions raised by the scholars on site. No one knew more about the research on Zhou's conjecture than him.

At the end, a classic scene appeared. Liu Yichen, the answerer, and Zhou Haizhong, the conjecture proposer, took a photo. This will become a good story in the Chinese mathematics community and even the world's mathematics community.

In the field of mathematics, although many conjectures have been proposed, the conjectures he proposed are often proved only after the death of the scholar who proposed the conjecture.

Very few mathematicians who propose mathematical conjectures live to see their conjectures proven, so Professor Zhou Haizhong is lucky.

"Liu Tingting, your brother is so amazing. I think his level in mathematics is even better than the school's mathematics teacher." At this time, in a corner, Liu Tingting and her friends were also participating in this report meeting, but the second

The person's identity at this time is a volunteer.

"I really don't understand, your brother is so good at math, why did you fail two math subjects last semester!" Xu Lifang looked at her friend in confusion.

"What else can I do? Isn't it just that he sucked away all my talent in mathematics?" Liu Tingting curled her lips and said angrily: "God is too biased. Originally, I should have a little talent in mathematics, but the results have changed.

onto him."

Speaking of mathematics, it is really a pain in Liu Tingting’s life.

She originally thought that the business administration major would no longer have to encounter mathematics, but it turned out that she had overthought it. She failed the advanced mathematics and linear algebra easily and without any suspense.

.

She was excellent in other courses, but because she failed two subjects, she had no chance of receiving any scholarship this semester, and she completely missed it.

There is no way, as the best university in Fujian Province, the students of Ludao University are quite good, and the competition is quite fierce.

If someone fails the exam, they will miss out on various scholarships because they lose too many points.

Since her second year in high school, she has always believed that Liu Yichen had transferred her mathematical talent away.

After completing this academic report, Liu Yichen was relatively relaxed. He listened to other people's academic reports. It has to be said that he was able to give an academic report at the Chinese Mathematicians Conference. The academic report was quite high-level. And listening to the academic report,

Liu Yichen also had a deeper impression of the presenters of academic reports.

On the morning of the last day, Liu Yichen's academic report on the hail conjecture was the finale report of the Chinese Mathematicians Conference and the last report of all majors, so it was not held in the number theory lecture hall, but in the auditorium.

Because of the previous turmoil at Princeton University and the corresponding video, everyone was most familiar with the process of proving the hail conjecture. Thousands of people poured into the entire auditorium, making the auditorium overcrowded.

In addition to the scholars participating in the Mathematicians Conference, there were also students from Ludao University and a few other students from local Ludao universities who came here to attend. Everyone looked attentively at Liu Yichen who was giving an academic report.

According to the academic report he gave at Princeton University, Liu Yichen reported in more detail this time. Liu Yichen hopes that his academic report can bring inspiration to more people and be helpful to their mathematical research. At the same time, he also hopes to attract mathematics students.

Gifted young people devote themselves to mathematics.

Mathematics may seem useless, but in fact it is the basis for the development of all natural subjects. Without mathematics, other natural subjects are impossible to discuss.

The Internet, CNC machine tools, aerospace, aviation and other industries, which one can do without mathematics?

If you want to become an industrial power, you must first become a mathematical power. If you want to realize the fourth industrial revolution, you must first have a sufficient number and strong enough mathematicians to solve theoretical things, build a good foundation, and lay a solid foundation.

Only then can the building of the Fourth Industrial Revolution be built.

"The Kakutani conjecture is a number theory problem, and it is also a complex analysis problem..." After Liu Yichen introduced the original proof method, he asked the staff to move a new blackboard, and the written blackboard was moved to

On the other side, he used another method to prove the hail conjecture.

Sometimes it is like this. Once a mathematical conjecture is proved in one way and the veil is removed, it can easily be proved in another way.

As early as 1994, l.berg and g.meinardus proved that the 3n1 conjecture is equivalent to the function equation h(z3)=h(z^6){h(z2)λh(λz2)λ2h(λ2z2)}/3z (where

The analytical function solution of λ=e^(2πi/3)) in the unit disk {z:|z|<1} is in the form of h(z)=h0h1z/(1z). (h0 and h2 are complex constants)

On this basis, Schleicher and others proved in 1998 that any integral function h(z) makes g(z)=z/2(1cosπz)(z1/2)/21/π

(1/2cosπz)sinπzh(z)sin2πz satisfies:nΦ(g).

Based on these two conclusions, he proved that there is an integer function h(z) by constructing an ingenious transcendental integral function, such that for each branch of g(z) and Φ(g) in the above conclusion, it contains a certain positive integer.

d, all exist z0∈d, making {g^ok(z0)}∞/k=1 converge to 1.

It is not difficult to deduce from this that the Kakutani conjecture is established!

Others obviously did not expect that in such a short period of time, Liu Yichen came up with another method to prove the Kakutani conjecture.

Immediately, scholars asked questions one after another, and Liu Yichen showed his style and answered every question.

At the end, there was warm applause in the auditorium. It was obvious that they all affirmed the brilliance of Liu Yichen's report. As for Liu Yichen's paper proving the 'hail conjecture', this will have to wait until his paper is approved by the mathematical community, which strictly prohibits argumentation.

, only then will a conclusion be truly given.

Proving a mathematical conjecture does not end with the publication of a paper. In the past hundred years, many papers have been overturned after they were published. To truly prove a mathematical conjecture, the mathematical community must reach a consensus, at least the major mathematical research institutions, Mathematics

The top ten universities in the professional university rankings must represent the true proof of mathematical conjectures.

It is only at this step that the conjectures in the textbook will be officially revised into mathematical theorems.

With the end of this academic lecture, the Chinese Mathematicians Conference officially held its closing ceremony, which also represented the conclusion of the current session of the Chinese Mathematicians Conference.

And Liu Yichen took a plane back to the capital that night.

Receiving the Chen Shengshen Mathematics Award as the youngest winner means that from now on, Liu Yichen will have a seat in the Chinese mathematics community. Moreover, at this Chinese Mathematicians Conference, he got to know many Chinese mathematicians and began to expand his

Network of people.

Of course, what really pleased Liu Yichen was that after winning the Chen Shengshen Mathematics Award, the system rewarded him with 3,000 points. During the lottery, he got a 0.3% increase in brain development, which was undoubtedly more rewarding than giving Liu Yichen 10 million.

Happy.

The increase in brain development means that his thinking will run faster, he will be smarter, he will learn faster, and his brain will be able to store more knowledge, which can be said to have many benefits.

He didn't know how his IQ compared with Tao Zhexuan, who was said to have an IQ of 230, but he thought he was among the smartest in the world.

Of course, Liu Yichen didn't take an IQ test. He thought it was quite boring. If the test showed that his IQ was only 100, it would be totally shameful.
Chapter completed!
