Section 318

So, he uploaded the paper to the Internet.

After doing this, he looked at the time and found that it was too late, so Xiao Yi did not stay any longer, contacted Wang Li to get in the car, and then went back to rest.

...

Perhaps Xiao Yi had not uploaded the paper on his website for a long time. For a while, the paper was not discovered immediately after it was uploaded.

Probably because it was late, most people had already rested, even those self-media who were obsessed with logging on to the website every day to see if they could see the "surprise", most of them had stopped working at this time.

As for people abroad, they would not log on to Xiao Yi's website when they had nothing to do. Therefore, every time there was a new paper on Xiao Yi's personal website, the news was often spread from China first.

However, the self-media did not look it up, but someone else did.

And this person was Liang Qiushi who got the "inside information".

Because he had completed the paper, he was very happy that night and was ready to have fun with his fiancée who was about to get married in a few months.

While singing in a KTV, he suddenly slapped his head, took out his mobile phone, logged into his mentor's personal website, and then he saw a brand new paper on the website.

The name of the paper is very simple, it is called "Hail Conjecture", both Chinese and English versions.

He immediately slapped his thigh and said "Fuck".

Seeing his excitement, his girlfriend next to him stopped singing and asked, "What's wrong?"

"Look, my teacher's personal website."

"Professor Xiao?"

Knowing that it was something related to Xiao Yi, his girlfriend became curious.

She also tried to apply for Xiao Yi's student, but failed in the end. Of course, she would not complain about this. Anyway, there were countless students who were under Xiao Yi's hand at the time, and she did not have much advantage compared to those others.

However, it did not prevent her from being interested in Professor Xiao's affairs.

After all, she was studying nuclear physics, and Xiao Yi solved one of the most important problems in their nuclear physics - how to achieve controlled nuclear fusion power generation.

Therefore, none of those who study nuclear physics do not admire Xiao Yi.

That is to say, Xiao Yi does not teach in their physics department, otherwise, the door would probably be broken.

"Look at this paper, it is the latest achievement of my mentor."

Liang Qiushi showed it to his girlfriend.

His girlfriend was stunned: "Hail conjecture? Is this another mathematical conjecture? Similar to the Goldbach conjecture?"

"Yes, you should have heard of this conjecture, it is written in the elementary school textbook."

Then, Liang Qiushi introduced to his girlfriend what this hail conjecture is like.

After understanding it, his girlfriend naturally did not know how difficult this problem was, after all, she was not specialized in mathematics, but anyway, she didn't know how powerful it was.

Especially when she learned that this problem had not been solved for decades, and the former mathematics master also said that the mathematics community was not ready to face such a problem.

"Professor Xiao is really amazing!" His girlfriend sighed.

"Of course!" Liang Qiushi had an expression of "I don't need you to say this", and then he began to share this matter with various groups he joined.

In order to spread this important event to more people.

In the mathematics world, another difficult mathematical conjecture has been solved.

"Hehe, this is first-hand information. Isn't it amazing? I saw it when I went to the teacher's office at noon today to report the completion of the paper to him." Liang Qiushi showed off in front of his girlfriend.

"Awesome." His girlfriend smiled: "Then can you be as good as Professor Xiao in the future?"

Liang Qiushi was depressed when he heard this question.

"What a joke, my mentor is simply not something that humans can surpass."

His girlfriend laughed and handed him the microphone again: "Okay, let's continue singing now. As we sing, maybe you will become as good as Professor Xiao."

"Okay, okay." Liang Qiushi naturally didn't believe in such a thing, but he took the microphone and started singing love songs with his girlfriend.

"Sister, you sit at the bow, brother walks on the shore..."

...

Liang Qiushi joined many groups, and naturally sent messages to many groups, including many mathematics groups.

So it didn't take long for the topic of [Chief Engineer Xiao solved the hail conjecture again] to spread directly in the domestic mathematics circle.

Domestic mathematical scholars, or students, were shocked.

For example, in one of the groups Liang Qiushi joined, called [China Mathematical Society Exchange Group], the relevant discussion exploded directly.

As the name suggests, this group was naturally organized by the China Mathematical Society. Liang Qiushi attended an academic conference before, and then others learned that he was Xiao Yi's student, so they invited him to join.

And now, Liang Qiushi naturally sent the message to this group, and suddenly, a lot of people appeared in this group.

[Ah? Is it true? Professor Xiao solved the hail conjecture again? ]

[It's true, you can see it on Professor Xiao's personal website! (Screenshot.jpg)]

Seeing that someone had actually posted a screenshot of Xiao Yi's personal website, they immediately became even more excited.

[Oh my god! I saw it too, it's true, Professor Xiao is awesome! ]

[I've downloaded the paper, wow, it's actually true! ]

[No, Chief Xiao has only recently developed controlled nuclear fusion, right? It's only been a few months, and then he solved the hailstone conjecture by the way? How did he do it? ]

[Look, you're asking again, you're still surprised by the new. ]

[I took a look, there are more than 60 pages in total, and I don't know if Professor Xiao really proved it successfully. ]

[Just kidding, Professor Xiao has published a paper, do you think it's really proved? Especially look at this abstract. ]

As he spoke, a screenshot of the paper abstract was posted in the group.

The abstract is simple, direct and clear: This paper transforms the hailstone conjecture into an inequality problem about the dimension of invariant vectors in the representation space through representation theory. By creating a recursive formula for dimension and applying the properties of vector space, it is proved that there is a unified upper bound for the dimension of invariant vector space, and thus the finiteness of the classification tree of the periodic orbit of the hailstone sequence is deduced, completing the proof of the hailstone conjecture.

Then, everyone in the group began to speculate how Xiao Yi completed the proof.

However, they soon gave up.

Representation theory?

Inequality problem of invariant vector dimension?

Classification tree of periodic orbit of hailstone sequence?

These are completely new fields and terms for the study of hailstone conjecture, which made those who wanted to deduce Xiao Yi's proof process through the abstract give up completely.

[No, what kind of proof is this by Xiao Shen? Prove the hailstone conjecture from representation theory? Can this thing really do it? ]

[I really don't understand it. Xiao Shen's ideas are always different from ours. ]

[……]

In the process of discussion among many mathematicians in this group, more and more people also knew about this major event.

Naturally, the news eventually spread abroad.

The international mathematics community is going to be lively again.

Chapter 264: Pass the math test?

The news spread completely until late at night.

At this time, Xiao Yi had already fallen asleep, but the mathematics community could not sleep at all.

For a time, there were discussions about this matter everywhere.

People were either amazed that Xiao Yi had just solved nuclear fusion and solved such a well-known mathematical conjecture a few months later, or they were amazed that Xiao Yi's idea of ​​solving the hail conjecture was really a bit unexpected.

And more people were amazed at how Xiao Yi's energy gave people a feeling of inexhaustibility. He was able to complete so many important results in succession. Doesn't he feel tired?

But in the end, when they thought of Xiao Yi's age, the question of whether he was tired or not was self-defeating.

...

China entered the night, and the other side of the earth entered the day.

Tao Zhexuan, who was far away in the United States, learned about this matter on this day.

"Wait, you mean, the hail conjecture has also been solved?"

At this time, Terence Tao, who was on the phone in the office, suddenly stood up and listened to the news told by the other party with a surprised face.

Although he didn't know the news at the first time, someone would naturally tell him.

After getting a positive answer from the other party, he asked: "Is it Xiao Yi? Did he solve it?"

"Terence, you can guess it's him so quickly?"

The other party was slightly surprised.

Terence Tao said: "In this world, besides him, who else can solve this problem now?"

"Especially after I heard that he had completed the research on controlled nuclear fusion, I guessed that he should spend time on theoretical research next."

"You are right."

"Okay, thank you for bringing me this news, I have to go and see his paper."
