At the moment when Lu Zhou said those words, the lecture hall was quiet for a few seconds.

Immediately afterward, there was a commotion in the lecture hall.

Lu Zhou could clearly hear that there was a hint of suppressed laughter in the whispering discussion.

Obviously, by the time he said that he had made the L manifold, many people had already recognized him.

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

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

It is not easy for most scholars to read all the papers in their field, let alone research outside the field.

Unless you have studied the differential geometry solution in partial differential equations 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 an L manifold is.

Not to mention, the millennial puzzle about the NS equation has been solved in less than a year.

Of course, Professor Botham's research involves this field after all, and he still knows a lot about L manifolds, at least not even the inventor of L manifolds.

But even so, it's too hard for most people to remember an unfamiliar and exotic face.

Not to mention a foreign Nobel Prize winner, even if it is a domestic Nobel Prize winner's appearance, he can't recognize it all!

The paper does not have a photo......

The old face gradually turned red, and he stared at Lu Zhou for a long time, and Professor Botham couldn't say a word.

You're a math guy who knows how to make L manifolds of P...... Such a thing is obviously impossible to say.

Taking a deep breath, he said stiffly.

"What did I use wrong?"

To be honest, even now, he doesn't think he's at fault.

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

And no matter how many times he checked, he was incredibly confident that his calculations were perfect.

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

"Can I use the blackboard?"

Unconvinced, Professor Botham made a gesture of please.

Anyway, the face has been lost, so it is better to be generous.

Looking at Lu Zhou, who got up and walked this way, Professor Botem, who was standing there with a blank face, comforted himself in his heart.

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

Picking up the blackboard eraser from the multimedia lectern, he thought for a moment in front of the heavily written blackboard, and then started to erase it directly from the middle part.

Regardless of the stiffness on the face of Professor Botham next to him, after wiping the blackboard, Lu Zhou threw the blackboard aside and picked up the chalk on the multimedia lectern.

"There is a fundamental misunderstanding about the understanding of the L manifold. The differential geometry method is an effective tool for solving partial differential equations, but it cannot be used directly like other methods. First, we have to construct a bilinear operator B'......"

This is a common occurrence in the field of mathematical physics.

An interesting tool has emerged in mathematics, and although physicists may not have fully understood it, this does not prevent them from using it directly.

If you use it correctly, they might have discovered new physics.

If you use it incorrectly......

It's just a good time to write another paper to demonstrate why it can't be used this way.

As he spoke, Lu Zhou continued to write on the board at the end of the line of equations that had been erased.

【μ（t）=e^（t△）·μ0+∫e^（t-t'）△B（μ（t‘），μ（t'））dt'】

"When we give an Schwartz divergence-free vector field μ0 to the equation and set the time interval I⊂[0,+∞), we can continue to define a generalized solution of the nonlinear equation N5 as a continuous mapping that obeys the integral equation μ(t), i.e., μ→N5df(R3)......"

Staring at the rows of equations on the blackboard, Professor Botham felt nothing but tingling in his scalp.

Although Lu Zhou's speech was not fast, he almost never paused.

Just keeping up with this guy's train of thought, he was already struggling.

If this guy is ready to come to the briefing to make things difficult for him, that's fine.

But if these things were made by him on the spot......

That's terrible!

You know, it took him a week to get the contents of his previous board book......

Compared with Professor Botham's struggle, most of the scholars sitting at the scene were confused.

In order to listen to this presentation, they studied the paper at the Kalam Nuclear Fusion Research Center for a long time, and now they are told that the calculation is wrong?

？？？

Excuse-me？

Sure enough, new physics isn't so easy to spot.

Of course, in addition to the confused majority, there are still a small number of scholars who are listening carefully and really understand what is on the blackboard.

Of all the people sitting in the lecture hall, only this part of the people can deeply appreciate the value of these calculations.

And for Lu Zhou, this is enough.

After writing the last line of the equation, looking at the refilled blackboard, Lu Zhou simply checked it, and finally nodded.

"That's pretty much it."

"We didn't get new physics, but it's an interesting phenomenon."

"I don't have much research on tokamaks, and I can't tell if these conclusions alone can solve the problem of magnetic surface tearing. However, from my personal point of view, given the uncertainty of the current inside the plasma, it is difficult to control the magnetic field inside the reactor even if we can perfectly construct the magnetic field we need through the outer field coil......"

Placing the chalk on the multimedia lectern, Lu Zhou nodded to Professor Botham, and then turned and walked off the stage.

The moment he stepped off the podium, the lecture hall burst into sparse applause.

Soon, the 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 and staring at his back as he disappeared at the entrance to the lecture hall, Professor Botham couldn't say a word, and finally silently took out his phone and took a picture of the blackboard.

Although admitting it made him unhappy.

But at the very least, the report will not be for nothing......

……

stared blankly at the equation on the blackboard, and couldn't say a word about the Dianci calendar, who had forgotten what the notes were.

Who am I?

Where am I?

Whose presentation am I listening to?

At this time, Senior Brother Fei, who was sitting next to him, suddenly sighed.

"Professor Lu is still awesome......"

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

He bet that even if it was their mentor, Professor Yu Jinsong, who was sitting here, he probably wouldn't be much better.

Nodding a little bewilderedly, he came back to his senses and swallowed and spit.

"yes......"

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

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

Fei Jingqi smiled a little bitterly.

"I guess it's in vain."

It was falsified in less than half an hour.

The British professor is also strangely pitiful......

The two exchanged glances, silent.

MMP。

I couldn't have known it so early.
