Chapter 905: who are you? !! (four four)

? Yang Yongan froze.
The young man with glasses also froze.
The air froze for a few seconds.
"... Hodge conjecture?"
The expression was full of weirdness. Yang Yong'an glanced at the blackboard and glanced at the young man. The expression in his eyes could not tell whether he was looking at a lunatic or an idiot.
He used to think that this guy was a weirdo.
I heard that this guy has been researching something incomprehensible outside the window since he joined the International Mathematical Research Center, because a result can not be achieved, and even the office has been vacated to newcomers.
If you change to someone with a good sense of mind, you must have resigned, but this guy is different. After being kicked out of the office, he moved here with a small bench.
I do n’t know if it ’s really stupid or fake stupid. This guy did n’t feel bullied at all. When asked why he did n’t leave, he just casually answered
I like the quiet here
and then continued to do his own thing. .
When I first joined this math center with hidden dragons and crouching tigers, Yang Yongan thought that this guy was a kind of Chen Jingrun scholar who "won't sing, then slams". As time passed, he became familiar here, and he gradually doubted himself His thoughts, like other colleagues here, did not give him any good looks over time.
After all, there are also two or three years. Counting how long this guy has been sitting here, it may have been four or five years. In four or five years, one achievement cannot be achieved. Such a person has only two brushes, which is no different from a waste.
Leaving aside time for study, the golden age of a mathematician's life is only ten or twenty years. For four or five years, I was struck by an unthinkable problem, which was really stupid.
Now I heard that this guy is deliberately studying the millennium problem, and he is even more convinced of the guess in his heart.
80% of this guy is crazy.
Although he was looked at with the same fool's eyes, 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 studying?"
If some elderly people in the Mathematics Center see what they are studying, it is not worth his surprise.
But people who met for the first time, or even the first time they saw these things written on the blackboard, recognized the problem they were studying, which was a bit scary. Flash Dance Novel Network
After all, for most people, math, across different fields of study, is like a mountain. Wanting people who study partial differential equations to understand topologically complex continuous changes is no different from asking physicists to memorize complex names in organic chemistry.
Especially for century problems like Hodge's conjecture, even people who know this field, but because of different research ideas, they may not be able to understand what they write on the blackboard.
What's more, this is only a draft of him, and no word shows that it is related to Hodge's conjecture.
unless……
He is also a scholar working in this field!
Thinking of it, there was a little expression of interest in those pupils with little emotion.
Lu Zhou smiled and said, "It's not difficult to see this. Except for Hodge's conjecture, few algebraic topologies of nonsingular complex algebraic clusters can produce such wonderful things with polynomial equations that define subcluster. Relevance. But for people who do n’t understand this field, it ’s really easy to see, after all, the more difficult the topic, the more complicated the expression, the more upset it is.

"Yeah," there was a little emotion or excitement in the pupil with few emotions, the young man sighed, "I have been here for almost five years, a person who can discuss nothing."
"That's not too much, maybe some people know it, but just don't want to discuss it with you," Lu Zhou smiled and stretched out his right hand. "Can you use chalk for a while?"
The young man pushed his glasses and handed out the chalk in his hand.
"Please ... but there is not much space on the blackboard."
"This is not a problem," Lu said, looking at Yang Yongan next to him. "Trouble Professor Yang, help me to come over the blackboard."
Yang Yongan, who was still there while being talked by Lu Zhou, suddenly turned back and nodded quickly.
"Okay, okay! Just a moment, the most important thing here is the blackboard!"
With that said, he trot to the nearest side building, and soon brought two scientific research dogs, dragged a blackboard on a roller stand back to the big banyan tree.
Lu Zhou smiled and nodded his gratitude to the three, and then converged the expression on his face, stared at the blackboard for a moment and thought, and raised the chalk in his hand to write on it. 35xs
...
In fact, Hodge's conjecture is not a research area of ​​Lu Zhou.
However, because of the inherent connection between this problem and the Cauchy-Riemann equation, Lu Zhou is no stranger to it. And this unknown young scholar's use of the super elliptic curve analysis method made on the blackboard has given Lu Zhou some inspiration.
If the study of the Riemann conjecture can build a bridge between algebra and geometry, then similar to the Atia-Singh index theorem, the solution to the Hodge conjecture will be in the other three branches of mathematics-mathematical analysis, Some basic internal connection was found between topology and algebraic geometry.
Of course, he was not trying to prove Hodge's conjecture.
After all, even him, it is impossible to solve a difficult problem that has been recognized by the Clay Institute and the entire mathematical community for a century in such a short period of time.
However, the Hodge conjecture, like the Riemann conjecture, has many weak forms.
For example, for the case of h2, the Hodge conjecture holds!
Just as Lu Zhou was concentrating on calculations, in the side building not far from here, 60 people were selected through the exam to be selected into the national training team of the io contest. They had just heard the words of the former academician Wang Shicheng, the former chairman of the Chinese Mathematical Society Now it's free time for rest.
Sitting next to the window, the boy in the peaked cap was turning the book in his hand. At this moment, the little fat man in the front row suddenly turned around and looked at him excitedly.
"Ji, someone is pretending to be in the yard!"
"Not interested in."
Seeing that his buddies were not interested, the little fat man reluctantly continued: "It seems to be a king of the ranks! I just glanced at it when I passed by the toilet just now, and I couldn't understand what he wrote!"
Qingxiu's eyebrows finally raised a radiance of interest, and the teenager in the peaked cap dropped the book in his hand and glanced out the window.
"Go and see!"
...
There are more and more calculations on the blackboard.
Unconsciously, there were already many onlookers standing beside.
Most professors at the Mathematics Center recognize Lu Zhou's face. Although it is laborious to understand what he writes, most people sit hungry and take notes or listen attentively.
There are also high school students who apparently do not look like academics. They are also on the sidelines. They are all members of the national training team of the io contest and "mathematical geniuses" of high schools around the country.
However, standing here and now, looking at the string of calculations flowing like notes on the blackboard, in addition to the aggressive writing on the faces of these little cute newcomers, there are also many people who have created a world that belongs to the masters. A fascination.
Someday, they will reach that height.
The person standing under the tree at this moment, and the formula that writes the truth of the world at this moment, is their future!
The boy in the peaked cap stared, his shoulders shaking with excitement.
The little fat man standing next to him looked at his buddy and asked babblefully.
"Ji, are you jerking?"
"Big God! This is the real Big God! I seem to have seen him somewhere ..."
"Impossible, this is our first visit to Yanda University."
"No, I'm sure I remember correctly, I think again ..."
After finishing the training, I went to the office for a cup of tea and paced slowly to Academician Wang Shicheng, who was preparing to go to Academician Lu who would come from a long distance. Something is written next to it.
Frowning, Wang Shicheng stepped forward, stood beside the crowd, and looked at the contents on the blackboard.
However, the moment his eyes fell on the blackboard, his pupils involuntarily contracted.
Hodge conjecture
Although this is not his field of study, it is not difficult for a veteran scholar who has been studying mathematics for decades to recognize it.
What's more, he also recognizes that the "strange man" who is famous at the mathematical center standing next to Lu Zhou knows that it is Chen Yang who has studied the Hodgs conjecture for more than ten years without colliding with the south wall!
Time passed for an hour in silence.
With the gradual faint sun, the shadow of the banyan tree moved unconsciously to the east a few inches.
Everyone consciously kept quiet.
Until a soft sigh came from behind.
"... Hodge's conjecture holds for h2 ... awesome!"
Hearing this ghost-like voice, Yang Yongan was almost scared to fall. When I looked back, I found out that I do not know when the old academician Wang Shicheng stood behind him.
"To the hospital, academician!"
"Shh, keep quiet, don't disturb others," Wang Shicheng pointed at the blackboard with his chin. "It's finishing."
Having settled down, Yang Yongan lowered his voice and asked respectfully.
"... You mean, he proved a weak form?"
"No, you ca n’t count it as proof," Wang Shicheng shook his head in a sinking face, thinking for a moment, and said, "If I remember correctly, this result was by Levsetz in the 1920s. finished."
After a pause, the old man continued.
"However, although this is not a novel result, he used a completely different method from Professor Levsetz!"
"At least in my impression, no one has ever solved Hodge's conjecture like this."
Yang Yongan felt a great shock.
A completely different approach!
Proof of the weak form of a century's puzzle!
And just within this two-hour period? !!
This……
Is this the strength of Academician Lu?
The shock written in his eyes ~ EbookFREE.me ~ became more and more intense.
"It is indeed the first young scholar in mathematics today," Wang Shicheng sighed with a shocked expression in his eyes. "His understanding of differential manifolds and complex analysis and topology can be said to be three points."
Such scholars are not in their center of mathematics ...
It's a pity ...
"Inconceivable ... classify all manifolds in a given homotopy, and your definition of a hyperelliptic curve ..."
When Lu Zhou's last stroke stopped and looked at the formula on the blackboard, the young man's voice was already shaking with a bit.
It's not just shock.
Even more ecstatic!
"I'm Chen Yang, math ... associate professor."
"who are you?"
Do you know the self-reported home before asking people's names?
Although it is "weird", it is quite polite.
With a smile, Lu Zhou rested the unused chalk lightly under the blackboard and said lightly.
"Jinling Number Academy."
"Lu Zhou."
