Chapter 420: Are geniuses all this willful?

Standing by the window for 5 minutes, taking a few breaths of fresh air in the morning, Xu Qingzhou sat at the desk again and continued last night's calculation.

"If f(z) is a polynomial, and z=a is its k-level zero point, then f(z) can be divided by (z-a)^k..."

After solving the Landau-Siegel zero point problem, there is a feeling of sudden enlightenment. Although every step is difficult, for such a problem that has troubled the mathematical world for more than 160 years, the progress can be described as rapid.

He even had an illusion.

Perhaps it won't take long to get this century-old problem done.

Four hours passed quietly, at 2:00 PM, Xu Qingzhou tidied up the manuscript and prepared to go to Professor Roberts' side.

MIT.

"Hi, good afternoon, Xu." Hua Er En was still very enthusiastic. After a long time, this senior restored the image of the first time they met, and not to mention, there was a bit of dashing temperament in the sloppiness.

"Good afternoon."

Xu Qingzhou waved to greet, and had given up correcting Hua Er En's pronunciation.

"Your current course has been listed as one of the most popular courses at MIT, congratulations." Hua Er En smiled and handed Xu Qingzhou coffee.

"Thank you. The coffee is very good."

"I'm glad you like it."

"What interesting problems are there this time?" Professor Roberts stopped the calculation in his hand.

For Xu Qingzhou's research on the Riemann Hypothesis, neither he nor Hua Er En held much hope.

Very simple, Xu Qingzhou discovered a new particle.

This is of course something worth being happy about.

But this shows that Xu Qingzhou's main energy in the previous period was completely placed on particle physics, indicating that Xu Qingzhou himself was not confident in continuing the Riemann Hypothesis, and turned to research particles.

However, they all understood Xu Qingzhou.

Not to mention the Riemann Hypothesis, just the Landau-Siegel zero point problem is quite difficult.

This time, Xu Qingzhou is very likely to return without success.

"Before discussing, I think you will be more interested in this." Xu Qingzhou said, and sent the file in the mailbox to Professor Roberts.

"What?"

Xu Qingzhou sipped his coffee and laughed: "Paper, proof of the Landau-Siegel zero point problem."

"."

The office appeared weirdly quiet.

Professor Roberts' expression froze, and Hua Er En's hand holding the coffee paused, looking at Xu Qingzhou in amazement.

The news came a bit suddenly.

Professor Roberts was the first to come back to his senses and immediately opened the email Xu Qingzhou sent.

Hua Er En also hurriedly leaned over. On the screen was a paper 101 pages long, "Inequality Real Number Sequence"...

From the abstract and the review in front, one could already see many bright spots.

Professor Roberts finished reading the abstract, his eyes full of amazement, paused, and said in a deep voice: "I need time to verify... when do you plan to publish?"

Xu Qingzhou drank coffee. Although he knew there were many places that could be simplified, he had absolute confidence in the correctness of the paper and said: "Currently quite busy, this is still a draft, no time to organize..."

The proof of the Landau-Siegel zero point problem is 101 pages long, and to organize it all, it would take at least 10 days.

Compared to organizing the paper, he was more interested in solving the Riemann Hypothesis.

"."

Professor Roberts and Hua Er En both fell silent.

Are geniuses all this willful?

This is a result that can shake the mathematical world.

The reason for delaying publication is not any logical problem, just because—no time to organize.

It sounds... a bit absurd.

"As far as I know, there are many mathematicians currently conducting research on the Landau-Siegel zero point conjecture. By the way, Mr. Zhang Yitang, also from your Xia Nation, is also conducting research in this area."

Professor Roberts reminded.

Hua Er En also said: "Yes, yes, Cambridge, Princeton, Berkeley, all have research groups doing this topic."

Xu Qingzhou pondered for a moment, nodded, and said: "I will post the paper on arxiv first, and then modify it slowly later."

Although he cares more about the Riemann Hypothesis, it would be a loss if someone else published it first.

Arxiv is a preprint website for papers. Many scientists first submit their papers to this website and then hand them over to professional journals. It can be roughly seen as occupying a pit, indicating to others that you have already done this research.

Xu Qingzhou is in this situation, no time to modify the paper, so he threw the draft up first.

As for the plagiarism problem of peers.

There is no need to worry about this kind of relatively famous mathematical problem.

Just like the Poincaré conjecture in the past.

Perelman hung it on arxiv, while Cao and Zhu published it in asianjmath special issue, what was the result?

The former was held up to the sky, the latter was beaten into hell, and the nine clans were implicated.

Xu Qingzhou took out two complex function problems, intending to discuss them with Professor Roberts.

Described the residue theorem of the properties of functions near isolated singularities, and then there is the Cauchy integral theorem used to analyze the properties of the Riemann z-function on the complex plane.

Xu Qingzhou was responsible for the main lecture, saying his ideas, Professor Roberts and Hua Er En listened patiently. In the research of zero points, he really has the ability to be the teacher of these two now.

Around four o'clock, he refilled his coffee, and the topic transitioned from the Riemann z-function to Professor Roberts' topic, large-scale matrix calculation and its application in recommendation systems.

Discussing various matrix decomposition methods, such as singular value decomposition (svd), non-negative matrix decomposition (nmf), etc.

"I think, here we can give a definition first: given vector w, set w, mapping function m and relation, solve for a new mapping function m, and generate a new vector through it..."

"Yes! Xu, to be honest, I have already started to admire you a little." Hua Er En's face was uninhibited admiration.

"Studied it a little before."

Xu Qingzhou said.

He once used parallel computing and distributed computing technology to accelerate the calculation process when participating in the design of the density matrix of the Micius quantum satellite at the Quantum Research Institute.

Later, when helping Guo Ziyang make models, he also used parallel computing.

Therefore, he is quite familiar with this aspect.

Xu Qingzhou stayed in the office for a full 4 hours. It wasn't until 6:00 PM that the three of them noticed it was getting late, and then went to eat French food next to Massachusetts Avenue.

After eating, they were pulled by Professor Roberts and Hua Er En to discuss the sparse matrix processing problem.

And so, Xu Qingzhou didn't return home until 9:00 PM. He didn't even rest, cleaned the house inside and out, so as to welcome the school beauty Song who was returning from a business trip for a week.

After cleaning, he spent two hours putting the proof of the Landau-Siegel zero point problem on arxiv.

Just as he lay on the bed, he heard a "ding," which was a message from Song Yao.

Song Yao: "Teacher Xu, my breakfast, the sandwich doesn't taste as good as yours."

Xu Qingzhou clicked on the chat box, wanting to send a message to show off, but suddenly noticed the time.

1:30 AM.

Hiss, not good.

He hurriedly exited the chat.

But it was already too late.

Song Yao: "Xu Qingzhou, you haven't slept yet (kitchen knife)!"

Xu Qingzhou sighed and typed: "I said I just woke up, do you believe it?"

Song Yao: "What do you think."
