Almost just when the two fathers and sons of the Xing family took away, on arxiv., the world's paper preprint website, there were suddenly exactly ten more mathematical papers signed by Ningjie.

Seven of them are naturally the precursor papers of Ning Xiao's research on NP issues, and the other three are specially selected by Ning Xiao, each with its own use, such as making it easier for him to poach people, in short, ten of them will simply be sent to the pre-printed website together, which can be regarded as saying hello to everyone first.

In fact, generally speaking, if a student publishes a paper, it is best not to publish the paper on arxiv. before understanding the requirements of the journal or conference. This may lead to rejection of the paper by some well-known conferences or journals.

But for Ning Xiao, it's not a big problem.

It is difficult for any journal to refuse a Fields Medal winner submission, even if the article has been pre-published. After all, well-known mathematicians have some privileges. Of course, for Ning Xiao, it doesn't matter if he is really rejected.

Anyway, the purpose of publishing these papers is to make subsequent mathematical theories public.

With his current status in the world mathematics community, he doesn't really need to publish articles in the so-called top journals to prove himself.

Of course, in order to be recognized in the mathematical community as soon as possible, he still asked March to directly send the seven articles that need to be used in the near future to the "Annals of Mathematics" at one time. Peer review can be accepted by the academic community more quickly.

As for whether this operation will cause any trouble to peers and journal editors, it is not up to Ning Xiao to consider. He felt that Lu Xiaoya was right, he could be a man and didn't need to care too much about what others thought.

What if you think he's cheating?

He's cheating, what's up!

……

Cambridge, Boston Metropolitan Area, Massachusetts, USA.

It is famous for the world-renowned Harvard University, where Dominette Duncan once became a tenured professor. But many people don't know that the Clay Institute for Mathematics, which came up with the seven millennial math problems, is actually here.

Of course, if you really want to talk about the Clay Institute of Mathematics, which was co-founded by businessman Clay and Arthur Jeff, a great mathematician who teaches at Harvard University, of course, the money is mainly from Clay.

Eric Cady has just walked into his small office at the institute. During this time, he spent most of his time working at the Clay Institute, but he actually spent most of his time working at the Poincarat Institute.

He had the opportunity to pick his preferred environment from years ago.

A Russian hermit mathematician solved the Poincaren conjecture that he should have received the million-dollar prize promised by the Cray Institute of Mathematics. But the mathematician was too individual, and he refused to accept the prize outright, and he didn't want the prize. It's just that as a world-renowned institution dedicated to the dissemination of mathematics, of course the money that should have been taken out is embarrassed to take it back.

So the Clay Institute simply contacted the Poincarai Institute to discuss the possibility of using the one million dollars that should have been rejected as a Russian mathematician to sponsor a rising star in mathematics, and the money would be used to support his mathematical research.

It's just that this lucky winner needs to be selected layer by layer, and Eric Cady finally became such a lucky person after defeating many competitors. A standard bonus.

As a mature mathematician, Eric Cady naturally has his own pace of research.

In fact, for many mathematicians, ARXIV is concerned. The same goes for Eric Cady.

Although arxiv can upload papers as people and dogs, and papers have mixed flaws, if you only focus on your own research direction, there will be gold occasionally.

The most important thing is that the updates are frequent, almost every day, and just like the official journal, it also supports subscriptions. Anyway, it doesn't take a few minutes to take a look at it every day, but maybe there will be a surprise.

Eric Cady's favorite is the arxiv's ribbon because it's really convenient. Although it is free indexing, it is even more intimate than many official journals.

For example, its built-in bibliography browser, after opening, can display the references of the current article and the literature cited by the current article according to certain sorting rules and filter rules, and directly sort according to influence, which can help scholars quickly pay attention to the excellent papers in the current field.

Today, when he turned on the computer, he saw a prompt in the mailbox. According to the email prompt, there were two updates to the mathematics field he was concerned about, and to his surprise and surprise, one of them was from Ning Xiao of Huaxia Yanbei University of Physical Education.

It was quite a surprise indeed.

Generally speaking, when an academic scholar like Ning Xiao publishes a paper, he will give some lectures in advance to talk about the direction of his recent research and what results he has made. This can probably be understood as the process of building momentum.

In short, generally speaking, the paper has not yet been published, and everyone basically knows which field these academic masters will bring some surprises to the mathematical community in the future. And generally speaking, if you are not sure, these academic masters will not talk about their achievements everywhere.

So Ning Xiao's paper is somewhat sudden.

But it doesn't matter if it's sudden or not, it's definitely a pleasure in life to have this kind of freshly baked article to read every morning.

While waiting for the download, Eric Cady searched for Ning Xiao's name through arxiv's site indexing function. He hadn't seen Ning Xiao publish an article on this preprint website before, and wanted to see if there were any surprises.

Sure enough, there was a surprise, and it is difficult to even say whether it was a surprise or a fright.

This guy actually published ten papers on arxiv?

You must know that after the paper on Ning's NS equation was published in the Annals of Mathematics, Eric Cady searched for Ning's name on Arxiv, but at that time there was not even a single paper on Arxiv.

It's been less than a year since that paper was published, and it's crazy to think about how many papers there are so many Ning Xiao papers at once.

After all, who will be on the arxiv water papers?

There is no need for review, and there is no reviewer, so it is just released for people to see, which is completely meaningless.

Especially for a mathematician like Ning Xiao, who has a lot of attention, if the paper itself is not rigorous and there are big problems, it will also affect the reputation.

However, when Eric Cady entered the article page and checked the upload time of these articles, the whole person fell into doubts about the authenticity of this world.

Good guys, all ten papers were published not long ago, and the interval between each publication was about ten minutes, which is of course normal. After all, uploading a paper on ARXIV is not as cumbersome as submitting a paper to SCI, but there is no shortage of operations. Uploading an article in ten minutes is already extremely efficient.

But no matter how efficient the upload is, it is not as efficient as this water paper.

Eric Cady took a look at the ten articles and they belong to six different areas. Three of them are related to each other, and according to the analysis of the cited content on the function page, they are basically the content of their own papers.

This discovery did not make Eric Cady happy, on the contrary, he began to seriously doubt the quality of the paper he had just downloaded.

Let's put it this way, Eric Cady felt that even if Newton dared to publish ten papers a year in his time, it would be nothing. Not to mention that these papers also belong to different research directions.

For mathematicians, more than a month is not even enough time to switch their thinking from the original research direction to a new research field. After all, mathematics is a very broad concept in this era. Specializes in number theory of numbers, algebraic geometry, k-theory, discrete mathematics...... The content of the research is actually different.

The quality of a paper with a pile of water in a short period of time is naturally hard to believe.

Fortunately, by this time the paper had been downloaded, and Eric Cady decided to start working on the paper anyway, and then found that he was still superficial. What this paper says is that he came up with a conjecture and then proved it himself.

This mathematical conjecture is that if there is an F:m x [0 ,t)→n, where n is an n-dimensional manifold and m is a manifold of a certain dimension less than n, and f satisfies the equation ?f/?t=-h→, then there must be a way for this MCF to flow naturally through the singularity defined by it.

This formulation is abstract and also involves various geometries that have entropy problems in Euclidean geometry. But it is useful for Eric Cady, whose research direction is the correlation between the differential structure of four-dimensional manifolds and the bilinear form of four-dimensional manifolds.

This is where the average curvature flow comes in.

This is an extremely cutting-edge mathematical research direction, and now mainstream mathematicians are not sure what the coincidence number in the above equation is greater than 1, let alone how to make the MCF flow through these singularities. Because these singularities are entropically stable and cannot disappear through perturbations, it is still a mystery whether they can pass through these singularities at the geometry and topology levels, and if they can pass through these singularities.

Ning Xiao's paper seems to directly address this problem.

Eric Cady doesn't know what the other nine papers are, but he knows very well that if this paper really solves this problem, it will help many people who are working in this direction, such as he is one of the beneficiaries.

Just as he was about to read the paper in depth, the phone rang.

"Hey, Eric, I want to invite you to be a reviewer for a new paper, are you interested?"

"Huh? To be honest, Robert, I'm not really interested in it for the time being. ”

"No, no, no, Eric don't rush to refuse, the author of this paper is Ning Xiao. You may not have had dinner with him at the mathematicians' conference, but I think you know what the name represents. ”

Hearing this, Eric Cady was stunned, and then said very speechlessly: "Robert, in fact, I have just downloaded a paper by Ning Xiao on arxiv, and I am reading it, I suspect that the paper you invited me to review is the same paper I am reading. ”

"Oh? Have you downloaded it yet? Needless to say, I also read the paper he just posted on arxiv, and in fact this is probably the one that will interest you. ”

Eric Cady sighed and said, "Then what else can I say?" Of course I was happy to accept the invitation, but I felt a lot of pressure. So he submitted all those papers to the Annals of Mathematics? ”

"No, no, no, for the time being, only seven papers have been submitted to us."

Hearing this, Eric Cady was silent for a while, and then asked faintly, "Is it only seven?" To be honest, Mr. Robert, your wording suddenly makes me feel very frustrated, I don't know much about the situation with the other papers, but I have just finished reading the review of this paper, and if his argument is correct, then I can probably understand how Dominit Duncan felt when he spoke at the Congress of Mathematicians. ”

"Who's to say it isn't? Eric, but in this world, there are always people who exist as if they were wrong, very unreasonable. Scholars of their time were unfortunate, because perhaps everything they could have had would have been overshadowed by the light of such a person. But at the same time, they are also lucky, because problems that may not have been possible in their lifetime will end in their hands. It depends on what you think. ”

Hearing this, Eric Cady's depression finally eased a little, and he said, "Okay, Mr. Robert, you can send me the invitation link, and I will accept the invitation." By the way, did you choose me because Ning Xiao chose me to be his reviewer when he submitted his paper? ”

"Uh...... In fact, he did not appoint any reviewers. But Erik, I don't think you need to be offended at all, given his age and the fact that he doesn't interact with the outside world, it's conceivable that he probably doesn't know many people in the math community, so ...... Well, in fact, none of the papers he submitted had the expected reviewer. ”

I have to say that the words of the editor-in-chief of the Annals of Mathematics made Eric Cady feel a lot better.

This is probably the style of a great mathematician, probably Ning Xiao never thought about appointing a reviewer at all, right? Or maybe he doesn't care who is studying these things at all, because his hobbies are so broad that he may not have time to care who is studying them, so he just changes direction.

"Thank you for your doubts, if you can, you can help me bring a message to him and tell Ning Xiao that I am very honored to be a reviewer for his paper. Of course, if he makes any mistakes, I will definitely find out. ”

"Of course! Good luck. ”

"Thank you."

After hanging up the phone, it didn't take long for Eric Cady to receive an invitation link from the editor-in-chief of the Annals of Mathematics, and after gladly agreeing, he began this wonderful review journey.

……

Fields Medal winners in mathematics have cards after all.

Even now, more and more journals are using double-blind review, so they ask contributors not to pre-post their papers on pre-publication websites, but these established mathematicians will still choose to compromise even if they do.

He also began to look for suitable reviewers for many of Ning Xiao's papers.

It's a really novel experience, because it's a lot of work to be a good reviewer for seven papers at a time.

Not to mention that these papers were all published by the same person, in fact, it is not often for the Annals of Mathematics to decide to review seven papers on the same day. After all, 90% of manuscripts are eliminated by the editor at the first review.

Typical papers will find four to six reviewers, and even if the number of papers is the smallest, nearly 30 mathematicians will be contacted for seven articles.

The news that Ning Xiao uploaded ten papers on ARXIV at one time and submitted seven of them to the Annals of Mathematics quickly spread in the process.

Fortunately, it is still easy to find reviewers for Fields Medal-winning papers.

In fact, no one who contacted the mathematician for the first time chose to refuse, but not everyone had the habit of logging on to the arxiv website every day like Eric Cady, so after getting the news, he naturally subconsciously logged on to arxiv to see the demeanor of this paper water god.

Yes, many people have subconsciously put the nickname of the water god on Ning Xiao's head after hearing that Ning Xiao submitted seven papers to the "Annals of Mathematics" at one time. Regardless of the quality of these papers, but with this quantity alone, there will definitely be no mistake with the word water god.

Of course, other people's water papers are generally in small journals, and the kind belongs to water monsters.

Those who dare to challenge the top of the water can naturally be called gods.

But after many mathematicians read the review of the paper, the response was different.

Because after reading it, everyone feels that these papers really can't be described with water, because they are some problems that have not yet been solved in the mathematical community.

Basically, if you solve one of them, you are eligible to win a math prize...... After all, the world's mathematics prizes are not only the Fields Medal, the Abel Medal and the Wolf Medal, but also such as the Danzick Medal, the Bergman Prize, the Polya Prize, the Cole Prize, the Cafford Prize, the Gauss Prize, and so on......

It's just that these awards are not as well-known as a few international awards, but they are just as difficult to get.

Of course, if all seven papers are okay and all these problems are solved, it is not a question of winning a few awards, after all, the contribution to the mathematical community can be cumulative, just as quantitative change will lead to qualitative change.

At the same time, these papers also have a great impetus for some cutting-edge mathematical research directions.

Of course, the same is true of confusion......

With so many results published in a single day, it was like a magnitude 10 earthquake for the entire mathematical community.

Don't you play like this?

After all, some of these problems are already being studied by many mathematicians, and now someone has solved them all at once.

Yes, when most serious mathematicians see that row of papers, they probably feel as if there are countless grass and mud horses whistling through their minds, so that they begin to doubt the reality of this world.

Mathematicians can be efficient, but how can they be so efficient?

That Ning Xiao, he's crazy, isn't he?!

yes, he must be crazy, right?

……

Xu Shuqing also thought that Ning Xiao had gone crazy.

Of course, his arguments are not quite the same as those of mathematicians.

After all, who will pay back tens of billions to fight against others?

Especially when he received a call from the school at the hotel and learned that Xing Jianxin and his son had been taken away for investigation, he confirmed this.

Crazy, completely insane!

Originally, he thought that kicking Xing Jianxin out of Shuangdan at noon was a plus, who dared to think that people didn't think it was enough, this was unwilling to completely press Xing Jianxin to death.

This also directly led to more problems for him to consider.

If the chips are not enough, how can the two sides understand each other?

Just when his mind was as big as two, suddenly the phone rang again.

When he saw the number, Xu Shuqing had some bad feelings in his heart.

Because this call was made by Li Kecheng, the chief professor of the Pearl Mathematics Center of Shuangdan University, and this is also one of the few academicians and professors who made him feel relieved this morning.

This Professor Li is the only academician of the Chinese Academy of Sciences who received an invitation letter from Ningyuan of the University of Sports and the only three of those professors who directly stated to him that they would stay in Shuangdan.

It's just that there is nothing major, and Academician Li should not have called him again at this time.

But no matter how he felt, Xu Shuqing could only answer the phone immediately, and made his voice appear full and enthusiastic: "Hey, Academician Li, haven't you slept so late?" ”

"Hey, I can't sleep, Principal Xu. I also happen to have something to tell you, well, I changed my mind, and I still want to go to the University to have a look. ”

"No, Academician Li, what's the matter? Aren't you still helping me persuade everyone this morning? Why did you suddenly change your mind? ”

"Well, President Xu, you also know that I have been studying the research of high-dimensional nonlinear conservation law equations and shock waves for many years, and just now Ning Xiao uploaded a paper, which happens to fit my research, and I plan to take a look at ......"

"Huh? Ning Xiao published another paper? Where was it published? ”

"Actually, it's not a publication, he just pre-published ten papers in arxiv, and it is said that seven of them have been submitted to the Annals of Mathematics, of course, these are not important, the main thing is that one of his articles I just roughly skimmed through, how to say...... It is indeed very insightful, and many of the arguments are thought-provoking and thought-provoking...... So, hey, of course, I'll take over the work on Shuangdan's side......"

"This ...... Ten papers? That, Academician Li, okay, even if Ning Xiao has research in these directions, can we invite him to give a lecture in the name of academic exchanges? It doesn't have to be ...... in the past."

"Actually, I originally thought the same way, but let's not talk about Ning Xiao's character, in terms of the current relationship between the two schools, do you think you can really invite him to Mingzhu? Or if he gives a lecture in the capital, will he invite us? Ay...... Young people nowadays are not very easy to deal with. Anyway, I'm just going to inform you first, it's really an accident, I'm really sorry, Principal Xu. ”

After speaking, Professor Li hung up the phone without waiting for Xu Shuqing to reply.

Probably embarrassed to say anything more on the phone, Xu Shuqing actually has nothing to say, and now these words are full of tears.

I knew that it would develop into such a situation, and yesterday Ning Xiao proposed to kick Xing Jianxin out of Shuangdan, he should have agreed immediately without hesitation, but who would dare to think that it would develop like this in less than a day?

Also, What the hell are ten math papers?
