Chapter 469: 2 big problems

Chapter 469
"...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 scene was silent, all with stunned expressions.
The first question of the minimal model program, just like this... Is it easily solved?
They have an unrealistic feeling.
Especially in Cheng Nuo's relaxed and casual tone, he gave the answer to the question.
That feels...
It seems that the solution is not like the first problem of the minimal model program, which is famous in the field of birational geometry, but a test problem that is no longer ordinary.
Happiness~~!
Professor Fresnel, sitting in the first row, applauded first.
As the only mathematician in the audience who knew the subject of Cheng Nuo's report, he was dumbfounded when he talked to him about it a few days ago, so his expression is fairly flat now.
By the way, I can also see the embarrassing expressions of a few old friends.
After the other mathematicians glanced at each other, they all gave Cheng Nuo on the stage with a wry smile, and gave their own applause.
Murphy's law is true.
One thing, the less you don’t want him to happen, the more likely it will happen.
Before the start of the report, they were very unwilling to believe that Cheng Nuo had solved the problem of the minimal model program, but in reality, Cheng Nuo, with such a relaxed and casual attitude, solved this problem that lasted for nearly 50 years. .
"Mr. Cheng Nuo, can we say that you have solved the first problem of the minimal model program?"
The question was a journalist responsible for following up a certain scientific journal of the International Geometry Symposium.
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 raised his hand and asked questions.
"No." Cheng Nuo's words left many of the following scholars at the same time stunned and 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 directly sprayed out.
By the way... By the way? !
Professor Fresnel also rubbed his eyebrows and looked helpless.
Hey, I am a student who is good everywhere, but I don't know how to save some face for others.
Cheng Nuo gestured to the man in a daze to sit down, shrugged, and said helplessly, "As I said before, the difficulty of the minimal model program has been deliberately exaggerated by some people. In fact, everyone here here, It is estimated that it will not take much effort."
I believe in your ghost! You young man is very bad!
Few of the mathematicians 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, it wasn't a shame to study other fields.
If the minimal model program is really as easy to solve as Cheng Nuo said, it will never stand in the realm of dual rational geometry for more than 50 years!
Originally, Cheng Nuo's ability to solve the first problem of the minimal model program had already shocked them. Now, I learned that Cheng Nuo had dealt with two major problems in one go.
Many people are already thinking about life.
Cheng Nuo stood on the stage and ignored the psychological activities of the mathematicians below.
The time allocated to him by the conference was only fifty minutes. Half of it has now passed. There is still one question that has not been addressed. He has not much time to delay.
Cheng Nuo said loudly, "The second question of the so-called minimal model program is to ask whether the flip operation is terminated after a finite number of times. Since we have proved the existence of the flip operation before, then this issue is necessary for discussion! "
"After my deduction, the answer is that the flip operation is terminating, that is, this operation will stop after a limited number of times!"
"Next, I will talk about the specific derivation process. Let's first assume that this operation will not terminate after a limited number of times, then..."
Twenty minutes later.
"... Formula eleven is the same as Formula 8, substituting the unit ring in the three-dimensional algebraic cluster. After three-step derivation, it is found that the result obtained is contradictory to the previous condition three.
"Therefore, the flip operation is terminated after a limited number of times. As for the number of terminations, I also figured it out, which is the 8741780462th."
In order to use mathematical language to explain his solution clearly within the limited time, Cheng Nuo had to deliberately speed up some speech.
Cheng Nuo unscrewed a bottle of mineral water on the lecture table and drank it.
While drinking, his eyes kept paying attention to the audience below.
Professor Fresnel gave a thumbs up quietly.
The muddy eyes of another Philippine award boss looked at Cheng Nuo curiously.
Most other mathematicians frowned and thought.
The amount of information that Cheng Nuo throws out is so great that even if all of them are creative and agile, it is difficult to keep up with Cheng Nuo's ideas.
Cheng Nuo smiled, "Don't worry, everyone, I have compiled the derivation process of the two major issues of the minimal model program into two papers, and upload the preprint to arxiv, you can download and verify at any time."
Cheng Nuo raised his wrist to check the time.
The fifty-minute report time is over.
Smiling, he bowed slightly and said a short closing remark.
"My report is over, thank you all."
After speaking, the three steps turned into two steps to step down when everyone did not react.
Until Cheng Nuo returned to his seat, the endless applause sounded like a tsunami.
The content of Cheng Nuo's report today deserves such applause.
Since then, the two mountains on the path of the Mini-Model Program have been removed.
The rest is a smooth journey!
In terms of academic nature, the solution to the two major problems of the minimal model program is naturally not comparable to the proof of the two major conjectures in the geometric world some time ago.
However, the solution of the two major problems will make a rather unpopular research direction in the field of geometry a super hot topic.
At this time, it happens to be the time when many master and doctoral students choose their graduation topics.
After the news that the two major problems of the minimal model program have been resolved, one can imagine how many graduate students will be attracted to choose this direction.
From the door can be a bird, UU reading www.uukanshu. Com to the doorstep, relying on only one person.
Cheng Nuo, this name, was deeply engraved in the heart by more than 400 mathematicians participating in this conference.
So far, none of them regard age as one of the standards for measuring Cheng Nuo's academic level.
Because they could not find any reference.
Among the mathematicians in history, they couldn't find any one who reached such a level at Cheng Nuo's age.
Once in ten years?
Or is it a century?
Or, once in a thousand years?
They suddenly remembered what Professor Fresnel said about Cheng Nuo in private.
"The Fresnel Award, for Cheng Nuo, is just a matter of time."
