"Let A be an arbitrary subset of the density on the positive relative, so limN →∞π(N)...... This theorem is the Somerdy theorem. ”

"It's been mentioned many times in my report."

"And in the rest of my talk, I will also focus on the application of this theorem."

"First of all, we can easily come to the conclusion that almost all positive integers N satisfy the law ......"

【Col(N)< f（N）……】

Li Mu's report began, and off the stage, all the audience also followed his train of thought and began to think.

The ability of the vast majority of the audience in this audience is not comparable to that of ordinary students.

Not to mention, more than half of them can be called mathematicians.

To be able to attend a joint math conference, you must first understand mathematics, either as a math major, or find a way to prove yourself as a math enthusiast.

As a result, there were basically not many people distracted, even those who were sitting in the aisle listened attentively to Li Mu's report.

Minutes and seconds passed.

In the back of the audience, Lin Yao was also here, after all, as Li Mu's teacher, of course he couldn't be absent from his students' reports.

Looking at Li Mu on the stage, he was full of amazement.

Before, he had always thought that the report that Li Mu planned to publish was about the Adama conjecture, so he never asked about the specific content of the report, at most he reminded Li Mu to submit the content of the report to the official in advance.

It wasn't until the meeting was about to start that he went to the official website to check the specific information of Li Mu's report, and then he found out that this kid was actually talking about hail conjectures.

The surprise in his heart was incomprehensible, especially when he saw that Li Mu's report had already studied this conjecture to such a deep extent.

The hail conjecture is obviously the most unique of all mathematical problems.

Because even compared to Goldbach's conjecture, the statement of the hail conjecture is much easier to understand.

It's such a minimalist problem and extremely difficult combination to prove that the mathematical community is fascinated.

It's just that when Li Mu started to study the hail conjecture, Lin Yao didn't know a little.

It can only be said that as a teacher who has watched Li Mu develop from an ordinary student to today's point, he feels that he can no longer keep up with Li Mu's realm.

With a slight sigh in his heart, he looked at the well-known mathematicians sitting in the front row, as Li Mu's teacher, he was embarrassed to sit in the front just now.

That's the influence of the hail conjecture.

Much larger than Adama conjecture.

……

Compared with Lin Yao's exclamation, what others around were amazed by was Li Mu's rigor in the process of narrating.

Mathematicians love this kind of rigor.

Because rigor is the characteristic of mathematics.

In the third row, several professors from Princeton University sat together, looking at Li Mu with admiration in their eyes.

Professor Peter Sanak couldn't help but praise: "This kind of speech is amazing, and it is very rare that such a young man can have such an unflawed logic." ”

Deligne also nodded slightly, and said with a smile: "It's like his previous paper." ”

"yes."

Peter Sanak bows.

"Is that the proof paper on the Adama conjecture?"

Another old mathematician next to him asked.

The veteran mathematician, Enrico Pomberi, was also a Fields Medal winner and a tenured fellow at the Institute for Advanced Study in Princeton.

Anyway, there are no fewer Fields Medal winners who came to participate in Li Mu's report.

"Yes." Deligne nodded, "You should have read that paper." ”

"Well, you told me about it at the beginning." Pembery nodded, and then sighed: "I remember that the paper was also very well written, rigorously structured, and clearly stated, this young man can indeed be called a genius mathematician." ”

Deligne and Sanak both smiled.

After all, Li Mu had been unanimously approved by the two of them as early as in that paper.

Suddenly, at this moment, another person's voice came from the side: "Anyway, have you noticed that what he is talking about now seems to be a little different from his report?" ”

The three turned to look at the man who spoke.

Andrew Wiles, proover of Fermat's theorem.

His proof of Fermat's theorem made an exception for the Fields Medal, which had been awarded only to mathematicians under the age of 40.

At the age of 44, he was awarded a special Fields Prize for his proof of Fermat's theorem.

The influence of Fermat's theorem in the mathematical community is too great, and proving him also shows that Wiles's mathematical ability is enough to rank among the top in the world.

Therefore, his words also aroused the doubts of Deligne.

"What's a little different?"

They stopped their previous exclamation and turned their attention to Li Mu's speech.

Gradually, they did find that Li Mu's content was different from the original report.

Before the report, they all handed out a paper version of Li Mu's report, which was intended to help them take notes or find questions.

Now when they compare them, they find that the content added by Li Muxin seems to point to a deeper level.

Deligne's brows condensed, and his mathematical intuition made him clear that Li Muxin's addition of these contents was definitely to pave the way for a certain conclusion later.

Which conclusion will it be?

Speculation suddenly occurred in his mind.

"Yes! Could it be that these new additions to him ......" Sanak next to him already showed a surprised expression at this time.

"Shhhh Let's not speculate, let's wait for Li Mu to reveal the answer for us. ”

Deligne's eyes were fixed on Li Mu on the podium, "Perhaps, today's mathematics is really going to have a perfect Valentine's Day." ”

The others didn't say much anymore and listened to Li Mu's speech quietly.

And the people who discovered this were not only Drinne, but also other well-known mathematicians such as Tao Zhexuan and Faltins had also discovered the discrepancies between Li Mu's speech and the original report.

And Li Mu's new content, after combining it with the original text, seems to be ...... No, it should be obvious that it all points to the last piece of the puzzle left in the original report.

"It's getting interesting."

Faltins sat up straight, interested.

Tao Zhexuan also reacted in the same way: "It seems that the proof of the hail conjecture will have nothing to do with me." ”

……

Li Mu's narration gradually came to the end of the original report.

He turned his head and smiled at the audience.

"At this point, my report is over."

Just when Deligne and the others were stunned, he smiled again: "And next, is my real Valentine's Day gift for mathematics." ”

Turning around, he picked up his pen and began to write on the blackboard in the conference room.

【P(v[1，k]=(j， l))《……】

Several new forms in succession seem to have lifted the clouds and reproduced the day of truth.

Off the field, Tao Zhexuan, Faltings, Deligne...... The great mathematicians and so on, all had amazement on their faces.

A perfect Valentine's Day gift, and so was born.
