Chapter 466

Chapter 469

" In this way, through the series connection of these five formulas, it can be easily concluded that flip operation exists! "

Cheng Nuo's loud voice reverberates clearly throughout the auditorium.

The whole scene was silent, and all of them were stunned.

The first problem of minimalist program, that's it Solved easily?

They have a sense of unreality.

Especially in Cheng Nuona's relaxed and casual tone, he gave the answer to the question.

That feeling

It seems that the solution is not the first problem of minimal model program, which is famous in the field of Bi rational geometry, but a common test problem.

Pa Pa Pa ~ ~!

Professor Fresnel, sitting in the first row, clapped first.

As the only mathematician who knows the subject of Cheng Nuo's report, he was stunned when he talked to him about it a few days ago, so his expression is still flat.

By the way, I can also see the expressions of some old friends making a fool of themselves.

Many other mathematicians looked at each other and gave their applause to Cheng Nuo on the stage with a wry smile.

Murphy's law is right.

One thing, the less you want it to happen, the more likely it will happen.

Before the beginning of the report, they were very reluctant to believe that Cheng Nuo had solved the problem of minimal model program. However, in reality, it was Cheng Nuo who solved this problem for nearly 50 years with such a relaxed and casual attitude.

"Mr. Cheng Nuo, can we say that you have solved the first problem of minimal model program?"

The question was asked by a reporter who was responsible for following up on a scientific journal of the international geometric Symposium.

His keen perception let him know that this must be a big news, so he couldn't wait for the report to end, so he couldn't wait to raise his hand to ask questions.

"Not really." Cheng Nuo's words let many mathematicians at the same time, confused.

But the following sentence will make the scene boiling.

"To be exact, I have not only solved the first problem of minimalist program, but also solved the second problem of minimalist program by the way." Cheng Nuo smiles.

Poof!

Some big guy who drinks coffee down there sprays it directly.

Shun incidentally?!

Professor Fresnel is also rubbing eyebrows, a helpless face.

Ah, my student is good everywhere, but I don't know how to save face for others.

Cheng Nuo motioned to the man who was in a confused state to sit down, shrugged his shoulders and said helplessly, "as I said before, the difficulty of the minimal model program has been deliberately exaggerated by some people. In fact, it is estimated that it will not take much effort for all of you here to come."

I believe in your ghost! You are a very bad young man!

Few of the mathematicians here have been immersed in the field of geometry for more than ten years, and many of them have tried to solve the two major problems of minimal model program.

But as a result, I have not studied other fields in the end.

If the minimal model program is as easy to solve as Cheng Nuo said, it will never stand in the field of double rational geometry for more than 50 years!

Originally, they were shocked that Cheng Nuo could solve the first problem of minimal model program. Now, I learned that Cheng Nuo put two big problems in one breath.

Many people are already thinking about life.

Cheng Nuo stood on the stage, but did not care about the psychological activities of the group of mathematicians below.

The time given to him by the general assembly is only 50 minutes. Now half of the time has passed. There is still one problem that he has not talked about. He has not much time to delay.

Cheng Nuolang said, "the second problem of the so-called minimal model program is whether the flip operation is terminated after a finite number of times. Since we have proved the existence of flip operation, it is necessary to discuss this problem! "

"After my derivation, the answer is that the flip operation has termination, that is, the operation will stop after a limited number of times!"

I'm going to talk about the derivation process. Let's assume that this operation will not terminate after a finite number of times, then... "

Twenty minutes later.

“…… Formula 11 is the same as that of formula 8, and is substituted into the element ring of three-dimensional algebraic family. After three-step derivation, it is found that the result obtained is in contradiction with the previous condition

"Therefore, the flip operation is terminated after a limited number of times. As for the number of times of termination, I have also calculated it. It is 8741780462. "

In order to use mathematical language to explain his solution clearly in limited time, Cheng Nuo has to speed up some of his speech speed.

Cheng Nuo unscrewed a bottle of mineral water on the speech table and drank it.

While drinking, his eyes were always on the audience below.

Professor Fresnel quietly raised his thumb.Another Fei prize winner's turbid eyes are full of curiosity to look at Cheng Nuo.

Most of the rest of the mathematicians frown and ponder.

The amount of information that Cheng Nuo throws out is too large, even if they are all quick witted people, they can't keep up with Cheng Nuo's ideas.

Cheng Nuo chuckled. "Don't worry. I've sorted out the derivation process of the two major problems of the minimalist model into two papers. I'll upload the preprint to arXiv. You can download and verify it at any time."

Cheng Nuo raises his wrist and looks at the time.

The 50 minute report time is over.

With a smile, he bowed slightly and said a short concluding remark.

"That's the end of my report. Thank you."

With that, he still stepped down in two steps when the public did not respond.

Until Cheng Nuo returned to his seat, clapping and clapping like wisps of applause just sounded like a sea roar.

The content of Cheng Nuo's report today deserves such applause.

Since then, two mountains on the path of Minimalist Program exploration have been removed.

The rest is a smooth road!

In terms of academic nature, the solution of the two major problems of minimal model program is naturally not as good as the proof of the two major conjectures in the geometric world some time ago.

However, the solution of the two problems will make a rather cold research direction in the field of geometry and become a super hot topic.

Now this period of time is just when many master's and doctoral students choose their graduation projects.

After the news that the two major problems of minimal model program have been solved, we can imagine how many graduate students will be attracted to choose this direction.

From a few people to a large number of people, we only rely on one person.

Cheng Nuo, the name, was deeply engraved in the heart of more than 400 mathematicians who participated in this conference.

So far, none of them regard age as one of the criteria to measure Cheng Nuo's academic level.

Because they can't find any reference.

Among mathematicians in history, none of them reached such a level at Cheng Nuo's age.

Once a decade?

Or a hundred years?

Or is it a millennium?

They suddenly remembered Professor Fresnel's comment on Cheng Nuo in private.

"The Fresnel prize, for Cheng Nuo, is just a matter of time."
