Chapter 466 Two Big Problems
469 chapter

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

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

The whole place was silent, with dumbfounded expressions on their faces.

The first problem of the minimal model program, just like this...was solved easily?
They have a sense of unreality.

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

That feeling...

It seems that what is solved is not the first problem of the program of minimal models, which is well-known in the field of dual rational geometry, but a very common test question.

clap clap ~ ~!

Professor Fresnel, who was sitting in the first row, applauded first.

As the only mathematician in the room who knew the subject of Cheng Nuo's report, he had been dumbfounded when he talked to him about it a few days ago, so his expression was quite flat now.

By the way, you can also see the embarrassing expressions of some old friends.

After looking at each other, many other mathematicians gave Cheng Nuo their applause generously with wry smiles on their faces.

Murphy's Law is indeed true.

One thing, the more you don't want him to happen, the more likely it will happen.

Before the report started, they were very unwilling to believe that Cheng Nuo had solved the problem of the minimal model program, but in reality, it was Cheng Nuo who solved this nearly 50-year-old problem with such a relaxed attitude.

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

The questioner was a reporter who was responsible for following up a scientific journal of this International Symposium on Geometry.

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

"No." Cheng Nuo's words stunned many mathematicians below at the same time, confused.

But the following sentence made the scene boil instantly.

"To be precise, I not only solved the first problem of the minimal model program, but also solved the second problem of the minimal model program by the way." Cheng Nuo smiled slightly.

puff--!
A certain boss who was drinking coffee below sprayed it out.

By the way...by the way? !

Professor Fresnel was also rubbing between his brows, with a helpless expression on his face.

Hey, I am a good student, I just don't know how to save face for others.

Cheng Nuo signaled the stupefied man to sit down, shrugged, and said helplessly, "As I said before, the difficulty of the minimal model program has been exaggerated on purpose by some people. In fact, everyone here, It probably won’t take much work.”

I believe your ghost!You young man is very bad!

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

But as a result, in the end, I didn't go to study other fields in disgrace.

If the minimal model program is really as easy to solve as Cheng Nuo said, it will never stand in the field of dual rational geometry for more than 50 years!
Originally, they were shocked that Cheng Nuo could solve the first problem of the minimal model program.Now, I learned that Cheng Nuo actually solved two major problems in one breath.

Many people are already thinking about life.

Standing on the stage, Cheng Nuo didn't care about the mental activities of the group of mathematicians below.

The time allocated to him by the conference was only 10 minutes, and now half of it has passed, and there is still one question that has not been discussed, so he doesn't have much time to waste.

Cheng Nuo said loudly, "The second question of the so-called minimal model program is to ask whether the flip operation will terminate after a finite number of times. Since we have already proved the existence of the flip operation, it is necessary to discuss this issue! "

"After my derivation, the answer I got is that the flip operation is terminating, that is, this operation will stop after a finite number of times!"

"Now, let me talk about the specific derivation process. Let's first assume that this operation will not terminate after a finite number of times, then..."

Two 10 minutes later.

"...The derivation ideas of Formula [-] and Formula [-] are substituted into the unit ring in the three-dimensional algebraic cluster. After three steps of derivation, it is found that the result obtained is contradictory to the previous condition three."

"Therefore, the flip operation is terminated after a finite number of times. As for the number of times of this termination, I have also calculated it, which is the 8741780462nd time."

In order to explain his solution in mathematical language as clearly as possible within the limited time, Cheng Nuo had to deliberately speed up his speech.

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

While drinking, he kept his eyes on the audience below.

Professor Fresnel quietly gave a thumbs up.

The cloudy eyes of another Filipino award boss looked at Cheng Nuo curiously.

Most of the rest of the mathematicians were frowning in thought.

The amount of information Cheng Nuo threw out was too much, even though they were all quick-witted, it was difficult for them to keep up with Cheng Nuo's train of thought.

Cheng Nuo smiled, "Don't worry, everyone. I have compiled the derivation process of the two major problems of the minimal model program into two papers, and uploaded the preprint to arxiv. You can download and verify it at any time."

Cheng Nuo raised his wrist to check the time.

Five 10-minute reporting time ends.

Smiling, he bowed slightly and said a short concluding remark.

"My report is over, thank you all."

After finishing speaking, before everyone reacted, three steps turned into two steps to step down.

It wasn't until Cheng Nuo returned to his seat that there was continuous applause like a tsunami.

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

Since then, the two big mountains on the road to explore the minimal model program have been removed.

The rest is a smooth journey!
In terms of academicity, the solution to the two major problems of the minimal model program is naturally not as good as the proof of the two major conjectures in the geometry world some time ago.

However, the solution of the two major problems will turn a relatively unpopular research direction in the field of geometry into a super hot topic.

At this time, many master's and doctoral students are choosing their graduation topics.

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

From sparsely populated to crowded, relying on only one person.

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

So far, none of them has considered age as one of the criteria for judging Cheng Nuo's academic level.

Because, they can't find any reference.

Among the mathematicians in history, they couldn't find a single one who had reached such a level at Cheng Nuo's age.

Come out every ten years?
Or once in a century?
Or, once in a thousand years?
They suddenly remembered what Professor Fresnel had said about Cheng Nuo in private.

"For Cheng Nuo, the Fresnel Award is just a matter of time."
