Chapter 905

Yang Yong'an was stunned.

The young man in glasses also froze.

The air froze for a few seconds.

“…… Hodge's guess? "

The expression was full of oddities. Yang Yong'an glanced at the blackboard and then at the young man. He could not tell whether he was looking at a madman or an idiot.

He used to think this guy was a weirdo.

It's said that since he joined the International Center for mathematical research, he has been studying something out of the window, which is hard to understand, because he can't make any achievements, and even his office has been vacated for new people.

If you change to someone who knows the world, you must have resigned voluntarily, but this guy is different. After he was kicked out of the office, he moved a small bench and sat here.

I don't know whether it's true or false. This guy didn't feel bullied at all. When asked why he didn't leave, he just casually replied "like the silence here", and then he continued to do his own business.

When Yang Yong'an first joined the math center, he thought that this guy was a Chen Jingrun scholar who was "silent, astonishing". As a result, he became familiar here for a long time, and gradually doubted his own ideas. Over time, he didn't give him a good face like other colleagues here.

After all, it's been two or three years. It's probably four or five years since this guy sat here. Four or five years a result can not come out, such a person has so two brushes, and is no different from a waste.

Despite the time of study, the golden age of a mathematician's life is only ten or twenty years. It's stupid to spend four or five years focusing on an unexpected problem.

Now it's said that this guy is studying the millennial problem in a delusional way. He's even more determined in his own mind.

This guy must be crazy.

Although he was looked at with the eyes of a fool, the young man with glasses didn't feel much, just looked at Lu Zhou and pushed down his glasses in surprise.

"You See what I'm working on? "

If some old people in the math center can see what they are studying, it is not surprising to him.

But it's a bit scary to be recognized by people who meet for the first time, or even see what they've written on the blackboard, what they're really working on.

After all, mathematics, for most people, is separated from different research fields, just like a mountain. It's no different to let physicists memorize the complex names of people in organic chemistry if they want people who study PDEs to understand the complex continuous changes in topology.

Especially for the century puzzle like Hodge's conjecture, even those who have some knowledge of this field, they may not be able to understand what they have written on the blackboard because of different research ideas.

What's more, it's just a draft of him. There's no word that shows it has something to do with Hodge's conjecture.

Unless

He is also a scholar in this field!

Think of here, that does not have in the pupil of what sentiment undulates, also gradually floated the expression of interest.

Lu Zhou smiled and said, "it's not difficult to see this. Except for Hodge's conjecture, there are few nonsingular complex algebraic clusters whose algebraic topology can be so wonderfully related to the polynomial equation that defines the sub cluster. But for people who don't know this field, it's really easy to see if it's true. After all, the more difficult the topic is, the more complex the expression is, the more cold it is. "

"Yes," said the young man with a sigh, "I have been here for nearly five years, and there is no one to discuss."

"That's not enough. Maybe some people know it, but they just don't want to discuss it with you." Lu Zhou smiled and held out his right hand. "Can I borrow chalk?"

The young man pushed his glasses and handed out the chalk in his hand.

"Please But there are not many places on the blackboard. "

"It doesn't matter," Lu Zhou said, looking at Yang Yong'an beside him. "Please, Professor Yang, help me get the blackboard quickly."

Being told by Lu Zhou, Yang Yong'an, who was still in a daze there, suddenly returned to his senses and quickly nodded his head.

"Yes, yes! Please wait a moment. The most important thing here is the blackboard! "

With that, he trotted to the nearest side building, and soon came back to the big banyan with two research dogs and a blackboard on the roller bracket.

Lu Zhou smiled and nodded to the three people to express his gratitude. Then he restrained his joking expression on his face, stared at the blackboard and pondered for a while. He raised the chalk in his hand and wrote on it.

According to Lefschetz hyperplane theorem, the inclusion mapping I: x ^ n (d) → CP ^ n + R is an n equivalent, so x ^ n (d) and CP ^ n have the same N skeleton ]……

In fact, Hodge's conjecture is not the research field of land boat.

However, because of the internal connection between this problem and the Cauchy Riemann equation, the land boat is not new to it. What's more, the unknown young scholar's use of the hyperelliptic curve analysis method on the blackboard gives some inspiration to the land boat.

If the study of Riemann's conjecture can build a bridge between algebra and geometry, then similar to Atia singer's index theorem, the solution of Hodge's conjecture will find some basic internal relations among the other three branches of mathematics, namely mathematical analysis, topology and algebraic geometry.

Of course, he is not trying to prove Hodge's conjecture.

After all, it's impossible for him to solve such a difficult problem in such a short period of time, which is recognized by Cray Research Institute and the whole mathematical world as requiring a century to solve.

However, like Riemann conjecture, Hodge conjecture has many weak forms.

For example, in the case of H ^ 2, Hodge's conjecture holds!

Just as Lu Zhou was concentrating on his calculation, in the side building not far from here, 60 people who had been selected into the national training team of IMO competition were selected through the examination. Just after listening to the lecture of the former president of the Chinese mathematics society, Wang Shicheng, an old academician, it's the rest time for free activities.

Sitting next to the window, the boy in the cap is turning over his books. At this time, the little fat man in the front row suddenly turned around and looked at him excitedly.

"Jige, someone is trying to force me in the yard!"

"No interest."

Seeing that his buddies are not interested, the little fat man continued unwillingly: "it seems that he is a big bull in the king's rank! I took a look when I passed the toilet just now. I can't understand what he wrote! "

The young man in the cap put down his books and looked out of the window.

"Go, look!"

……

There are more and more formulas on the blackboard.

Unconsciously, there are many onlookers standing nearby.

Most of the professors in the math center recognize the face of land boat. Although it's hard to understand what he wrote, most of them are eager to take notes or listen attentively.

There are also some high school students who are obviously not like scholars, who are also around. They are all members of the national training team of IMO competition and "mathematical talents" of high schools all over the country.

However, standing here and now, looking at a string of calculations flowing like notes on the blackboard, in addition to the ignorant force written on their faces, there are many people who are fascinated by the world of experts.

One day, they will be able to reach such a height.

The man who stands under the tree at the moment, the formula that writes the truth of the world at the moment, is their future!

The boy in the cap has round eyes and his shoulders are shaking excitedly.

The little fat man standing next to him looked at his brother and asked stupidly.

"Jige, what happened to your convulsion?"

"God! This is the real God! I seem to have met him somewhere... "

"It's impossible. This is our first visit to Yanda."

"No, no, I'm sure I remember correctly. I'll think about it again..."

After finishing the lecture, I went to the office to have a cup of tea, and walked slowly to Academician Wang Shicheng in the yard. I was about to go to academician Lu who would come from afar, but I didn't expect that they had already arrived first, and were standing beside a blackboard writing something.

Frowning, Wang Shicheng stepped forward, stood beside the crowd, and looked at the contents of the blackboard.

However, in the moment when his eyes fell on the blackboard, his pupils contracted involuntarily.

Hodge conjectures that although this is not his research field, it is not difficult for him, a veteran scholar who has been studying mathematics for decades, to recognize this.

What's more, the famous "weirdo" in the math center beside the boat also knows that it's Chen Yang who has studied Hodge's conjecture for more than ten years and never looked back after hitting the south wall!

Time passed an hour in silence.

With the gradual West slanting sun, the shadow of the banyan tree also moved a few inches to the East unconsciously.

Everyone is very conscious to keep quiet.

Until a light sigh came from behind.

“…… Hodge's conjecture holds for H ^ 2 How powerful! "

Hearing the voice like a ghost, Yang Yong'an almost didn't fall. Looking back, I found that when did Wang Shicheng stand behind him.

"To the court, academician!"

"Shh, keep your voice down, don't disturb others," Wang Shicheng pointed to the blackboard with his chin. "It's finishing."

After calming down, Yang Yong'an lowered his voice and asked respectfully.“…… Do you mean that he has proved a weak form? "

"No, it can't be proved by him," Wang Shicheng said after shaking his head like water and pondering for a moment. "If I remember correctly, this achievement was completed by levshetz in the 1920s."

After a pause, the old man continued.

"But while this was not a novel result, he used a different approach from Professor Lefschetz!"

"At least in my mind, no one has ever solved Hodge's conjecture in this way."

Yang Yong'an's heart is shaking.

A very different approach!

Proved the weak form of a century's puzzle!

And in an hour or two?!

This

Is this the strength of academician Lu?

The shock in his eyes is more and more intense.

"He is worthy of being the first young scholar in the field of mathematics today," Wang Shicheng said with a sigh. "His understanding of differential manifold and complex analysis as well as topology can be said to be very profound."

Such scholars are not in their mathematics Center

What a pity

"Incredible Classify all manifolds in a given homotopy, and your definition of hyperelliptic curve... "

When the last stroke of the boat stopped and looked at the formula on the blackboard, the young man's voice was shaking.

It's not just shock.

More with a little ecstasy!

"My dear Chen Yang, mathematics Associate professor. "

"Who are you?"

Do you know your name before you ask?

Although it's a "weirdo", it's polite.

With a smile, Lu Zhou put the unused chalk under the blackboard and said softly.

"Jinling Academy."

"Land boat."
