Chapter 213 The people in Shuyuan are indeed crazy.
"Are you sure it's the twin prime conjecture and not Kramer's theorem?" Xu Qingzhou looked strange.
After a mathematical conjecture is proven, it is very common for someone to want to falsify it. Even Fermat's Last Theorem, which has been proven for many years, some people are now thinking about how to find counterexamples.
It would be understandable if someone wanted to find out the mistakes in his proof of Kramer's theorem, but the proof of the twin prime conjecture was only published online three days ago.
"Well, it's the twin prime conjecture."
Ren Chujun nodded affirmatively and looked at Xu Qingzhou's calmness. She couldn't help but wonder: "Are you not worried at all?"
"I'm not worried, but I'm a little excited." Xu Qingzhou said in a deep voice.
"."
This kind of scene is like someone coming to slap you in the face, but the person involved shows a weird smile.
Jie, Jie, Jie, just hit me. The more you hit me, the more excited I will be!
Ren Chujun's face was solemn. I had heard before that people in mathematics at Beijing University were crazy, but now that I saw it, it seemed that this was really the case.
The reason why Xu Qingzhou is not worried at all is because such proven mathematical conjectures are very difficult to disprove, unless logical errors in the original proof are found or a new argument is proposed that contradicts the original proof.
The former is unlikely. Not to mention that he has checked it countless times himself. After submitting the manuscript, it has also been demonstrated by six top mathematicians.
As for the latter...if this person could provide a brand new perspective, he would have already taken the lead. It would be his turn to show off.
Xu Qingzhou quickly packed up his things and followed Ren Chujun out, wanting to see which general could be so brave.
At the same time, I am still a little curious about how the other party can refute him.
It's a pity that the two of them haven't seen the wonderful rebuttal argument yet. The warrior has already collapsed in the middle. He took his things and slipped away quietly. Xu Qingzhou could vaguely see the scrawled figure of the other party.
Thin and tall, wearing a washed-white brown jacket, Xu Qingzhou reminded him of Tang Zhijun in "Space Exploration Editorial Department".
There are still rows of formulas on the blackboard.
[Suppose a positive integer n, p is a prime number not greater than √(n+2), two numbers m and (m+2) that differ by 2, if m≠0modp when p≥5, the remaining congruential numbers are greater than the congruential numbers removed class, and p≤√(n+2).]
Next to these formulas, there are two rows of formulas. Judging from the handwriting, they were written by another person. As for the content, only two formulas were used to eliminate all the previous arguments of the person who wanted to falsify.
Senior Brother Zhang Hong came over and sighed: "He is a mathematics enthusiast. He must have sneaked in secretly. He talked a lot here. Professor Feng couldn't stand it anymore, so he went up to point out his mistakes."
Xu Qingzhou sighed, and the other party pointed out the problematic point, which happened to be the place where he guessed and wrote the asymptotic formula.
As for the formula on this big blackboard, after just a few glances, he found no less than three logical errors. For example, at the beginning, B(n) is not welldefined, and 0 is not defined to be coprime with a positive integer.
He discovered that this senior brother with two dark circles under his eyes seemed to have the same characteristics as the person just now, and he was obsessed with mathematics.
The difference is that Senior Brother Zhang is rational and what he pursues is not a castle in the air.
He accidentally saw Senior Brother Zhang's information a few days ago, including more than a dozen SCI papers, including many papers from Area 1. He is best at improving the Modi function and the RSA algorithm based on large number decomposition problems. He is considered an expert.
It is completely a standard academic template.
Studying mathematics usually requires profound mathematical skills and rigorous logical reasoning abilities, which are lacking in most civil sciences.
Zhang Hong invited: "There is a seminar on the characteristic theory of finite Abelian groups over there. Do you want to go and have a look?"
"I still have a discussion meeting." Xu Qingzhou said helplessly.
"I almost forgot, you are the protagonist today." Zhang Hong patted his head, with a pale smile on his face: "Okay, I won't disturb you." "Goodbye, senior brother."
Xu Qingzhou wanted to say that Senior Brother Zhang should pay attention to his health, but he also thought that people often told him not to work too hard in the past, but he didn't listen at the time, so he gave up.
There are about a dozen people waiting in Classroom 209, mostly foreigners.
"Hi, Xu, we meet again." Professor Maynard greeted Xu Qingzhou with a smile.
Xu Qingzhou stretched out his hand: "Professor Maynard."
After shaking hands, Professor Maynard introduced the white-haired old man next to Xu Qingzhou and said, "This is Professor Gerrit Boyle from Princeton."
"Hello, Professor Boyle." Xu Qingzhou extended his hand again. Unexpectedly, this person was one of the external reviewers of his paper.
Professor Boyle smiled and nodded: "Mr. Xu, we finally meet. Your argument is wonderful."
"Thank you." Xu Qingzhou thanked him.
"I have an old friend, Terence Chi-ShenTao. He originally wanted to come, but unfortunately, something went wrong with his schedule."
"It is indeed a pity, but I believe there will be a chance." Xu Qingzhou was surprised and said with a smile.
Terence Chi-Shen Tao is the famous Chinese mathematician Terence Tao. Although he is mainly engaged in the research of harmonic analysis, partial differential equations, and combinatorial mathematics, he is also involved in prime numbers.
Everyone did not exchange too many pleasantries and quickly got into the topic.
Different from the formal report meeting just now, Xu Qingzhou selected several important points to describe. Skip the previous introduction and go directly to the part about improving the sieving method, and then to explore the law of prime numbers.
Afterwards, everyone asked questions, and Xu Qingzhou was responsible for answering.
Near 12 o'clock, the seminar ended.
"You might consider studying algebraic geometry in depth. This thing is actually more closely related to algebraic number theory. It can provide us with another perspective to study the zeta function. Here the zeta function can be combined with a basic technique called cohomology. Get in touch.”
Professor Boyle marveled at Xu Qingzhou's youth and erudition. He paused and continued: "Perhaps, with this method, there is more hope of proving the Riemann Hypothesis."
He is familiar with the prime number theorem and has high attainments in algebraic geometry.
This young man from Xia Kingdom is so awesome.
Xu Qingzhou just thought about it for a moment, smiled and shook his head, "This problem is still too difficult for me. If there is a chance, I might work in this direction."
The twin prime conjecture alone had troubled him for half a year, let alone the first-tier Riemann hypothesis.
Professor Maynard must be great, but he can still only make a little progress.
Although he came back from rebirth, he always felt like he was cheating, but Xu Qingzhou was not strong enough to directly jump into the Riemann hypothesis.
Moreover, in terms of mathematics, his next focus is on the Polignac conjecture.
In the afternoon, after listening to the report meeting, Xu Qingzhou continued to classroom 209.
Professor Boyle went to find his old friend Mr. Wang Yiyuan. In addition to being interested in Xu Qingzhou, he was also invited by Mr. Wang to participate in the discussion of the sieve function of Goldbach's conjecture.
In the seminar, Professor Xu Qingzhou and Professor Maynard were the main narration and discussion people, and other scholars occasionally added some opinions.
