Chapter 507

The moment Lu Zhou said that sentence, the lecture hall was quiet for a few seconds.

Immediately afterwards, there were bursts of commotion in the lecture hall.

Lu Zhou could clearly hear, in the whispered discussion, there was still a trace of suppressed laughter.

Obviously, when he said that the L-manifold was made by him, many people had already recognized his identity.

Of course, there are also many people who are still confused, and are still waiting for the next article with a blank expression.

After all, what is known does not mean that everyone knows it, it only refers to those who have consulted the relevant literature.

For most scholars, it is not easy to read all the papers in this field, let alone research outside the field.

Unless you have studied the differential geometry solution in the partial differential equation in depth, and the proof of the existence and smoothness of the solution of the NS equation is studied, you may not have heard of what the L-manifold is.

Not to mention, it has been less than a year since the millennium problem of the NS equation was solved.

Of course, Professor Bottom's research involves this field after all, and he still knows a lot about L-manifolds, at least he doesn't even know who the inventor of L-manifolds is.

But even so, for most people, it is still too difficult to remember a strange foreign face.

Not to mention the foreign Nobel Prize winners, even the faces of the domestic Nobel Prize winners, he can't recognize them all!

There are no photos on the paper...

The old face gradually turned red, staring at Lu Zhou for a long time, Professor Bottom couldn't say a word.

You are just a math guy who understands the L-manifold of P... It is obviously impossible to say such things.

Taking a deep breath, he said bravely.

"Where did I use it wrong?"

To be honest, even now, he doesn't think he is wrong.

After all, he had checked his paper countless times before standing here.

And no matter how many times he checked, he was absolutely sure that his calculation process was perfect.

Looking at Botum who still didn't realize where the mistake was, Lu Zhou sighed.

"Can I use the blackboard?"

Although very unconvinced, Professor Bottom still made a gesture of invitation.

Anyway, I've already lost my face, so it's better to appear magnanimous.

Looking at Lu Zhou who stood up and walked towards this side, Professor Bottom, who was standing there with a blank face, comforted himself in his heart.

On the other side, Lu Zhou stepped onto the podium under the eyes of a pair of eyes.

Picking up the blackboard eraser from the multimedia desk, he thought for a moment facing the blackboard full of writing, and then started to erase directly from the middle.

No matter how stiff the face of Professor Bottom next to him was, after he finished wiping the blackboard, Lu Zhou threw the blackboard eraser aside and picked up the chalk on the multimedia desk.

"You have a fundamental misunderstanding about L-manifolds. Differential geometry is a powerful tool for solving partial differential equations, but it is not as straightforward as other methods. First, we have to construct A bilinear operator B'..."

This situation is very common in the field of mathematical physics.

A very interesting tool has appeared in mathematics. Although physicists may not fully understand this tool, this does not prevent them from using it directly.

If used correctly, they may discover new physics.

If you use it wrong...

Just another paper can be published to demonstrate why it can't be used in this way.

While speaking, Lu Zhou continued to write on the blackboard at the end of the line that was erased.

[μ(t)=e^(t△)·μ0+∫e^(t-t')△B(μ(t'), μ(t'))dt']

"When we give a Schwarz divergence-free vector field μ0 to the equation, set the time interval I[0, ﹢∞), and then we can continue to define a generalized solution N5 of the nonlinear equation as an integral equation obeying μ(t ), that is, μ→N5df(R3)…”

Staring at the lines of calculations on the blackboard, Professor Bottom felt his scalp go numb.

Although Lu Zhou's speech was not fast, there was almost no pause.

Just keeping up with this guy's train of thought is already very difficult for him.

If this guy is ready to make things difficult for him at the report meeting, then that's fine.

But if all these things were created by him on the spot...

That would be too scary!

You know, it took him a whole week to figure out the contents of his blackboard writing...

Compared to Professor Bottom's strenuous effort, most of the scholars sitting at the scene looked stunned.

In order to listen to this report, they have studied the paper of the Karam Nuclear Fusion Research Center for a long time, and now someone tells them that the calculation is wrong?

? ? ?

Excuse-me?

Sure enough, new physics is not so easy to discover.

Of course, apart from the bewildered majority, there are still a small number of scholars who are listening carefully and really understand the content on the blackboard.

Among all the people sitting in the lecture hall, only this part of people can deeply appreciate the value of these calculation formulas.

For Lu Zhou, this is enough.

After writing the last line of calculations, looking at the rewritten blackboard, Lu Zhou briefly checked it, and finally nodded.

"Basically that's it."

"Although we didn't get new physics, it's really an interesting phenomenon."

"I don't have much research on the tokamak, and I can't judge whether these conclusions can solve the problem of magnetic surface tearing. However, in my personal opinion, considering the uncertainty of the internal current of the plasma, even if we can perfectly It is also difficult to control the magnetic field inside the reactor through the external field coil to construct the magnetic field we need..."

Putting the chalk on the multimedia desk, Lu Zhou nodded to Professor Bottom, then turned and walked down the stage.

The moment his footsteps stepped off the podium, sparse applause resounded in the lecture hall.

Soon, those scholars and professors who were still in a daze also came back to their senses one after another, and sent their own applause along with those who applauded.

With thunderous applause echoing in his ears, Professor Bottom was unable to utter a word as he stared at the figure disappearing at the entrance of the lecture hall. Finally, he took out his mobile phone and took a picture at the blackboard silently.

Although it made him uncomfortable to admit it.

But at least, this report will not be for nothing...

...

Staring blankly at the calculations on the blackboard slowly, Dian Cili, who had forgotten what the notes were, couldn't say a word.

who I am?

where am I?

Who am I listening to?

At this time, Senior Brother Fei, who was sitting next to him, suddenly let out a long sigh.

"Professor Lu is still awesome..."

Although he didn't understand at all, his expression was not very depressed.

He bet that even if their tutor, Professor Yu Jinsong, was sitting here, their performance would not be much better.

Nodding in confusion, Dian Cili, who came back to his senses, swallowed.

"yes……"

Looking down at the several pages of notes in his hand, he suddenly realized a very serious problem, and was silent for a while.

"By the way, we just remembered this note..."

Fei Jingti smiled bitterly.

"I probably forgot."

It was falsified in less than half an hour.

This British professor is also very pitiful...

The two exchanged glances and remained silent.

MMP.

If I had known earlier, I would have missed it so early.
