Scholar’s Advanced Technological System

“of course can……”

Unexpectedly watching Fefferman Professor, Lu Zhou made a gesture of asking for the position in front of the whiteboard.

Picking up the marker, Fefferman Professor stared at the whiteboard and thought about it for a while, then wrote it on shua shua shua.

The time for class has arrived, but no one is sitting in the classroom.

Including Lu Zhou, everyone stared at the contents of the whiteboard.

Gradually, looking at the steps of the Fefferman Professor, Lu Zhou’s eyes shone slightly.

Wonderful…

The interesting places of mathematics are here.

A path that doesn’t work, no matter how long it takes, you can’t walk out of the maze.

However, a seemingly feasible idea does not even need to be close to the exit. From the moment you embark on this idea, you can have the feeling that the victory is ahead.

Although Fefferman has not yet written the final step, Lu Zhou is basically certain that his idea is not absolutely correct, but there is a probability that at least 90% or more is feasible!

Sure enough, the big cow did not let him down.

Smoothly fill the rest of the whiteboard, and Fefferman Professor draws the last stroke in the last row –

[Pμi:=μi-(Δ^-1)・δi・δj・μj]

There was a commotion in the classroom, although it was more difficult for the undergraduate students, but after all is Princeton, sitting here is the Mathematics Department student at the top of the subject scorn chain.

Not thinking about this step does not mean that no one can understand it.

Obviously, although they reacted a little slower, like Lu Zhou, they also saw the ingenuity of this idea from the steps of the Fefferman Professor.

Retrieving the marker printed on the whiteboard, Fefferman Professor carefully read the calculations he wrote down from the beginning to the end, then laughed and whispered.

“This question is not easy… it is a bit difficult for undergraduates.”

Lu Zhou lightly coughed: “So, it’s just a question.”

He was only going to meet with the students. If it wasn’t because so many people were interested in his research progress, he wouldn’t make this problem on the whiteboard.

What he didn’t even think about was that the big man would actually sit in the back row of the lecture hall.

Focusing on the content on the whiteboard, the scum on the Fewerman Professor touch the chin, thoughtfully said.

“Where (Δ^-1)·δi·δj is defined as the Fourier multiplier of ξiξj/|ξ|2… But what I want to know is, even if you have derived the equation of Pμi, what is the point? Can’t see it… is it convenient for me?”

“Of course,” this is not something worthy of concealing, Lu Zhou laughed, happy, “However, I need a new whiteboard.”

“The most important thing for Princeton is the place for the blackboard. I will help you get it.”

Throwing this sentence, Fefferman Professor turned around and left the lecture hall, and quickly dragged a whiteboard back from the next classroom.

Seeing the whiteboard that Feverman Professor dragged for himself, Lu Zhou was no longer polite, wiped the writing on the whiteboard, picked up the marker and started the book, and detailed his steps. Explanation.

“If we get Pμi:=μi-(Δ^-1)·δi·δj·μj, we can further find out by using the non-diverging property of μ for conventional integral…”

During this time, he has been busy experimenting. The research on the NS equation has only been carried out to the “Pμi:=?” step. As for the contents of the board on the whiteboard, it is actually derived on the spot.

This may sound a bit difficult.

But in fact, it is actually very easy to do this step.

After all, the idea is here, all he needs to do is to bring in the conclusions he has drawn before, and then continue to draw down along this line of thought.

However, this is easy, not without end…

[

The line was written on the whiteboard and the tip of Lu Zhou’s hand suddenly stopped.

Seeing this step, the original eyebrows of the Feverman Professor suddenly provoked a sharp arc of interest.

Lu Zhou took back the marker in his hand and cast a line of sight on him.

“What do you think?”

The index finger frantically rubbed the scum, and the Fefferman Professor said to himself.

“It seems… a little bit interesting.”

The eyes looked at the two men on the podium, and the students sitting in the classroom silently, for fear of making a little noise, interrupting the thinking of the two big men.

Throughout North America, there is probably no place to respect genius and respect knowledge more than Princeton.

In the past five minutes, the expression on the face of the Fefferman Professor suddenly disappeared, said in a relaxed tone.

“It seems that this problem is not so well solved.”

Lu Zhou, who is staring at the whiteboard, agrees nodded: “You are right.”

If it is so well resolved, the Cray Institute will not include it in the list of the seven major problems.

“But you can do this step, but it is beyond my expectation.” Laughed, Fefferman Professor and Yan Yue said, “The NS equation is an interesting question, it is the basis of fluid mechanics, and also in partial differential equations. The classic proposition. If it can solve the overall existence of its smooth solution, it is not only for the glory of the human mind, but also has a profound impact on a series of subjects associated with it.”

Diedone is one of the founders of the Bourbaki School. “Mathematics is for the glory of the human mind” is the famous saying he once said. Although Fefferman Professor does not agree with the Bourbaki School, he quite agrees with this sentence.

Having said that, Fefferman Professor smiled and clap his hands and raised his hand.

“A very fulfilling lesson… Although I may say that I might be a bit self-satisfied. What do you think?”

When it comes to the last sentence, he looks back to the classroom, the students who have not removed the fart from the bench even if they have already finished classes.

And responding to him, naturally it is the applause of the classroom.

Listening to thunderous applause, Lu Zhou was embarrassed to laughed.

Although he did not speak, his heart was actually somewhat smug.

The sense of accomplishment that the classroom brings to him is a completely different experience than a serious report.

It seems that even the entire semester has not seen each other, but his students still like him very much.

“Right, I made this question,” listened to the applause in the classroom gradually subsiding, Fefferman Professor suddenly remembered a thing, pointing to the calculations on the whiteboard, said in a humorous tone, ” Is there any use for your promise?”

Lu Zhou stunned and wondered.

“committed to?”

Sitting in the front row, the maroon long-haired girl who had previously asked him the question raised her hand and said with great interest.

“Professor, you said, if you made this question, you will accept him as your doctor.”

There was a creaking sound in the classroom.

Lu Zhou didn’t go to see the student who took the lead, and coughed and said: “You still don’t make a joke.”

“No, no, I am not kidding,” said Fefferman Professor laugh. “If you don’t mind receiving another Ph.D., I don’t mind reading a Ph.D. here.”

Although the tone of the Fefferman Professor is not a joke, Lu Zhou knows that he must be joking.

Compared with the Faltins Professor who has left Princeton, the Fefman Professor is completely at the extreme of “arrogance.” At the Princeton Institute of Advanced Studies, where he was genius, only he would play such a joke without hesitation.

Seeing Lu Zhou’s helpless expression, Fefferman coughed softly, stopped joking, and changed to a serious tone.

“Well, since you didn’t plan to receive another doctor, I hope you can promise me a request.”

Lu Zhou did not promise easily, but asked: “What request?”

“About the existence and smoothness of the solution of the three-dimensional incompressible Navier-Stokes equation,” paused for a moment, and Fefferman professor laughed, saying in earnest, “I hope to work with you to solve this problem!”

Sorry, ten minutes late.
