After returning from Brazil, Lu Zhou began research on plasma turbulence.

Although there is no retreat, his life is quite regular, basically three points and one line to and from the bedroom, Princeton Institute of Advanced Studies, pppl laboratory.

In terms of difficulty, it is not much easier to study the phenomenon of plasma turbulence than to study the properties of the ns equation.

Moreover, the difficulty of the two is even more difficult to agree.

The latter is equivalent to using abstract mathematical tools to prove whether the solution exists and is smooth. The former is equivalent to the specific case of the three-dimensional ns equation, and finds a "special solution" for a certain type of problem.

Until now, there have been only a hundred special solutions for the ns equation for different problems in the mathematics community, and most of them have either eliminated the time term or are limited to two-dimensional conditions.

As for cfd, or applied mathematics, most of the results are phenomenological models with empirical formulas and empirical parameters. For Lu Zhou, the meaning of reference is not very small.

And this means that Lu Zhou must complete this arduous work from the beginning, and even the literature that can be borrowed is not.

Of course, he is not completely unworthy of what he can rely on.

For example, the manifold created by him in the study of the ns equation is a useful theoretical tool in his view.

Not only that, after the conference came back, his mathematics level has been upgraded from lv6 to lv7, and only 3 levels are left from the full level lv10. The talent in mathematics and the intuition about numbers are not the same as a few weeks ago. And language.

Even without a 10% grasp, Lu Zhou has more than 90% of the grasp to solve this problem.

At most, it only takes a little time...

Just back to the third week of Princeton, August gradually came to an end, and Lu Zhou finally received a letter from the Clay Institute.

Dear Professor Lu Zhou, I am James Carlson, Chairman of the Scientific Advisory Board of the Clay Institute of Mathematics. 】

[According to the anonymous review of the 12 reviewers and the comments of the International Mathematical Union, we believe that you have completed the proof of the existence and smoothness of the solution to the ns equation. 】

[The solution of this problem will greatly promote the development and application of mathematical theory. We sincerely thank you for your contribution to the development of science in mathematics and the world. 】

[Based on the advice of your collaborator, Professor Charles Louis Fefferman, we are confident that your work will make a decisive contribution to this issue. So after voting by the Clay Institute board of directors, we decided to grant you a million dollar bonus in advance...]

The reason is that it is advanced, because every "millennial math problem" can not be won immediately.

According to the regulations, any solution must be published in a world-reputed journal of mathematics for at least two years, and recognized by the mathematics community, it is possible to review the decision by the Scientific Advisory Committee of the Clay Institute of Mathematics to decide whether to issue this million dollars. Grand prize.

However, this provision is not absolute.

For example, Perelman's paper has never been published in a "world-famous" mathematics journal. When Carlson, who was the director of the Cray Institute, visited the hermit in St. Petersburg, he did not wait for two years... ...

Of course, although Carlson finally did not see Perelman.

Considering that Lu Zhou’s report was held in the form of a special report at the International Congress of Mathematicians, and has answered all the controversial parts, it seems that there is no need to continue to wait for the consensus reached in the academic world.

So the Cray Institute made this decision.

In addition, in the mail, the Cray Institute also attached the conditions for receiving the award.

As a century proposition announced at the Millennium Conference, Carlson’s opinion is that he hopes to hold this award ceremony even more grand.

The awards were held at the French Academy in Paris, where the Clay Institute announced the mathematical problems of the Millennium. A special awarding ceremony will be held by the Clay Institute and the European Mathematical Society to present him with this million dollar prize.

As for what kind of ceremony, no one knows.

Because Perelman, who proved Poincaré's conjecture, was too individualized, even though the award ceremony was planned more than a decade ago, it has never been held so far.

For Carlson’s invitation, if it was a month ago, Lu Zhouxing would buy a ticket and fly to win the prize. After all, the one million dollar bonus will not be taken.

But now, his research on plasma turbulence is at a critical moment, neither willing nor interested in a distant journey.

After thinking for a while, Lu Zhou responded politely to an e-mail saying that he was studying the key period and couldn’t find time to fly to Paris. But at the same time he also stated in the letter that he did not reject the one million dollar bonus and attached his bank card account at the end of the mail.

The implication is that you just put the money on my card.

As for the medals or certificates, if you must send them to me, you can also post them by mail...

Seeing this email, Carlson almost didn't have a **** screen.

This is more irritating than the Perelman who let him eat the closed door.

The freak that shuts the door and sees no one is no problem. What is it that makes him directly fight money? !

How is the prover of the Millennium puzzle more than a wonderful one? !

Responding to an email, Carlson’s wording firmly told Lu Zhou that it was impossible.

As for the reason, it is very simple!

The millennium problem has been killed by two. The Cray Institute has planned more than ten years of awarding ceremony but it has not been held once. If you want to receive the prize, you have to come to Paris in person anyway.

Of course, in reply, Professor Carlson also said in a succinct manner that he understands how important the coherence of research is to a scholar.

If Lu Zhou can't find time, they are willing to discuss a suitable award date with him and hold this award ceremony.

Seeing the reply from Professor Carlson, Lu Zhou had a headache for the formalism of these guys.

The Cray Institute is located in Cambridge, Massachusetts, not too far away. He wants to go without even flying, and his Ford Explorer can pass.

However, these people are not willing to award prizes at their doorsteps. They have to go to the French Academy in Paris opposite the Atlantic to make an award ceremony.

And this sounds at least a waste of him for a week.

For Lu Zhou, who is working on an interesting research work, this is unacceptable.

After thinking about it, Lu Zhou continued to edit a reply letter.

[...I can't give you an accurate time, but after my research on plasma turbulence is fruitful, maybe I can take the time to accept the prize. 】

After the mail was edited, Lu Zhou clicked on the post, then turned off the mailbox and continued to ponder the experimental data in the computer for half a year.

When Professor Carlson, who was at the Cray Institute in Massachusetts, saw the e-mail, he did not say a word, but looked at his secretary Daft without a word.

Daft sighed and patted Professor Carlson's shoulder and silently comforted him: "...this is probably the most euphemistic rejection."

Although he is not studying fluid mechanics, not even academia, the particularity of the Cray Institute has led him to be exposed to many frontier research advances.

Turbulence is a well-known chaotic system, and it is also a problem that many physicists and mathematicians can't do.

Not to mention the object of research is the plasma...

In his opinion, this email is almost equivalent to rejection.

Taking off the eyes on the bridge of the nose, Carlson's arm was placed on the table, holding his eyebrows in a headache.

"I don't understand... Why? Why is it so hard to send money, so it's so difficult?"

He really feels tired.

When he was the former director, he felt this way. Now he is retiring from the second line as the chairman of the scientific advisory committee. His feelings have not changed.

He doesn't want anything now. The only wish is to stand in the halls of the French Academy before retiring, granting a million dollar bonus to the solver of the Millennium Challenge and a medal symbolizing honor.

But how can it be so difficult to achieve this wish?

Clearly have solved two...
