Chapter 213: People from the Math Academy are indeed all crazy

"Are you sure it's the twin prime conjecture, not Cramer's theorem?" Xu Qingzhou's expression was strange.

After a mathematical conjecture is proved, it is too common for someone to want to falsify it. Even Fermat's Last Theorem, which has been proved for many years, still has people thinking about how to find counterexamples.

If someone intended to pick out errors in his proof of Cramer's theorem, it could be understood, but the content of the proof of the twin prime conjecture was only published online 3 days ago.

"Yes, it's the twin prime conjecture."

Ren Chujun nodded affirmatively. Seeing Xu Qingzhou very calm, she couldn't help but feel some doubts: "You aren't worried at all?"

"Not worried; on the contrary, I'm a bit excited." Xu Qingzhou said in a deep voice.

"."

This kind of scene was like someone coming to slap him in the face, but the person involved showed a strange smile.

Read! {

It was a pity that the two of them hadn't seen a brilliant rebuttal argument yet; that brave warrior had already fallen halfway, taken his things, and slipped away quietly. Xu Qingzhou could vaguely see the person's sloppy back.

As for the latter... if this person could provide a brand-new perspective, he would have snatched it first; where would it be his turn to come and show off?

Ren Chujun's little face was solemn. She had heard before that people in Jingda Mathematics were all crazy, and seeing it now, it seemed it was really like that.

"It is indeed a pity, but I believe there will be opportunities." Xu Qingzhou was surprised for a moment, then said with a smile.

Professor Boyle marveled at Xu Qingzhou's youth and erudition, paused, and continued: "Perhaps, with the help of this means, there is more hope to prove the Riemann hypothesis."

Xu Qingzhou wanted to tell this Senior Zhang to take care of his health, but then thought that people often told him not to work too hard, but he hadn't listened at the time, so he gave up.

As for this large blackboard of formulas, just by looking at them for a few glances, he had already found no less than three logical errors. For example, at the beginning, b(n) was not well-defined; 0 being coprime to a positive integer was undefined.

He had accidentally seen Senior Zhang's information a few days ago: more than a dozen SCI papers, with no lack of Tier 1 papers. His best areas were the improvement of the MODI function and the RSA algorithm based on the large number factorization problem; he could be considered an expert.

In Classroom 209, there were about a dozen people waiting, basically all foreigners.

*Jie jie jie*, you just hit me; the more you hit, the more excited I get!

This young man from Xia Nation is too powerful.

Although he was reborn and always felt that he was like a cheat in the dark, Xu Qingzhou hadn't been stubborn enough to charge directly at the Riemann hypothesis.

"I have an old friend, Terence Chi-Shen Tao. He originally wanted to come over, but it's a pity, his itinerary had some problems."

Approaching 12:00, the seminar ended.

The former was unlikely; not to mention that he had verified it countless times himself, after submission, it had also undergone argumentation by 6 top mathematicians.

Senior Zhang Hong walked over and sighed: "He's a math enthusiast, probably sneaked in secretly. He said a lot here, and Professor Feng really couldn't stand it, so he went up to point out his errors."

"Perhaps you can consider delving into algebraic geometry. 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 linked to a basic technique called cohomology."

Just the twin prime conjecture had troubled him for half a year, let alone the Riemann hypothesis, which was in the first echelon.

Professor Boyle nodded with a smile: "Mr. Xu, we finally meet. Your argument is brilliant."

Xu Qingzhou sighed. The point the other person pointed out as problematic was exactly where he had written the asymptotic formula by guessing.

Next to these formulas, there were two more rows of formulas. Judging from the handwriting, they were written by another person. As for the content, just using two formulas, he had wiped out all the previous arguments of the person who wanted to falsify it.

The reason Xu Qingzhou wasn't worried at all was that mathematical conjectures like this that had already been verified were very difficult to falsify, unless a logical error in the original proof was found or a brand-new, contradictory argument was proposed. Thin and tall, wearing a brown jacket washed white, it reminded Xu Qingzhou of Tang Zhijun in *Journey to the West*.

It was completely a standard template for a top student.

"Hi, Xu, meet again." Professor Maynard smiled and greeted Xu Qingzhou.

"Professor Boyle, hello." Xu Qingzhou reached out again, not expecting this person to be one of the external reviewers of his paper.

"Almost forgot, you are the protagonist today." Zhang Hong patted his head, a pale smile pulling on his face: "Okay, then I won't disturb you." "Goodbye, senior brother."

After shaking hands, Professor Maynard introduced the white-haired old man next to him to Xu Qingzhou, saying: "This is Professor Greet Boyle from Princeton."

Xu Qingzhou only pondered for a moment, smiled, and shook his head: "This problem is still too difficult for me. If there is a chance, perhaps I will strive in this direction."

【Let positive integer n, p be a prime number not greater than √（n+2）, two numbers m and (m+2) with a difference of 2, if m≠0modp when p≥5, the remaining congruence classes are greater than the removed congruence classes, and p≤√（n+2）.】

The difference was that Senior Zhang was rational, and what he pursued was not a castle in the air.

Xu Qingzhou quickly packed his things and followed Ren Chujun out, wanting to see which department's general could be so brave.

He discovered that this senior brother with two dark circles seemed to have the same characteristics as the person just now, obsessed with mathematics as if he were possessed.

Professor Maynard is powerful, right? But he could still only make a little progress.

Terence Chi-Shen Tao is the famous Chinese-American mathematician Tao Zhexuan. Although he mainly engages in harmonic analysis, partial differential equations, and combinatorial mathematics research, he is also involved in prime numbers.

Zhang Hong invited: "There is a seminar on the character theory of finite Abelian groups over there. Do you want to go take a look?"

Researching mathematics usually requires a profound mathematical foundation and rigorous logical reasoning ability, which is what most amateur scientists lack.

!.

Different from the formal report meeting just now, Xu Qingzhou selected a few relatively important points to narrate. He skipped the introduction, went directly into the part about improving the sieve method, and then went to explore the laws of prime numbers.

On the blackboard, several rows of formulas remained.

At the same time, he was still a bit curious about what angle the other person could use to refute him.

"I have another discussion meeting." Xu Qingzhou said helplessly.

Xu Qingzhou reached out: "Professor Maynard."

"Thank you." Xu Qingzhou thanked him.

Everyone didn't have too much small talk and soon entered the theme.

Afterwards, everyone asked questions, and Xu Qingzhou was responsible for answering.

Familiar with the Prime Number Theorem, and also has high attainments in algebraic geometry.

Moreover, in this aspect of mathematics, his next focus was the Polignac conjecture.

In the afternoon, after listening to the report meeting, Xu Qingzhou continued to go to Classroom 209.

Professor Boyle went to find his old friend Old Gentleman Wang Yiyuan. Besides being interested in Xu Qingzhou, he also came here this time at the invitation of Old Gentleman Wang to participate in the discussion of the sieve function for the Goldbach conjecture.

In the discussion meeting, the main speakers and discussants were still Xu Qingzhou and Professor Maynard, and other scholars occasionally added some viewpoints.
