Chapter 149: On-the-spot proof

"Lin Yu, are you sure you're not joking?"

After a long while, the old man Chern came back to his senses, looked at Lin Yu with a calm expression unnaturally, and asked again.

He thought that the title of Lin Yu's report might be exciting, but he didn't expect it to be so exaggerated!

You know, this is a worldwide millennial problem, and if it is successfully solved, it will be enough to change the whole world!

In some respects, the solution of the NS equation is even more difficult than the Riemann conjecture, which is also one of the world's seven millennial problems.

Because it requires mathematical formulas, and the amount of calculations in various aspects, it is simply not something that people can solve.

So, when Lin Yu said that the title of his report today is the solution of the ns equation,

For the two old men, this is no longer a surprise, but a fright.

"Is it really the solution of the ns equation?"

Next to him, Qiu Chengtong couldn't help but ask.

"Hmm."

Looking at the disbelieving faces of the two old men, Lin Yu responded lightly, and then said with a serious expression: "It is indeed the solution of the ns equation." ā€

After hearing Lin Yu's definitive words, even though the two old men were mentally prepared, they were still shocked by the news.

"Could it be that you have successfully found the general solution of the ns equation?" In the middle of the ring, the old man Chern asked the most critical question.

Hearing this, the old man Qiu Chengtong next to him also looked at Lin Yu with burning eyes.

"Nope."

Seeing this, Lin Yu couldn't help coughing lightly, and said truthfully: "I haven't thought of it yet, but after I come to the stage, I should be able to try to calculate on the spot." ā€

ā€œā€¦ā€¦ā€

After listening to Lin Yu's words, the two old men were suddenly a little speechless.

They originally thought that Lin Yu had successfully solved the general solution of the ns equation, but they didn't expect him to even start to move the pen!

"Then what are you doing these days?"

Looking at Lin Yu with a calm face in front of him, the corner of the old man's eyes twitched and asked.

"Typing code in the room." Lin Yu said as a matter of course.

It's okay that Lin Yu didn't say this, but as soon as he said this, Qiu Chengtong next to him suddenly said angrily: "Our two old men thought that you were preparing the topic of the report meeting in the room, so they specially helped you deal with the matter of the imo competition, but now you are telling us that you are actually typing code in the room?" ā€

In the end, Qiu Chengtong's face became darker and darker, and he looked at Lin Yu very unhappily.

"Uh......"

Seeing this, Lin Yu smiled wryly, and then hurriedly explained: "I typed the code for another important matter, and this matter is more important than the year-end report meeting." ā€

"Besides, I'm not completely unprepared, didn't I already think that I would have to prove something later, and it would be the same when the time came."

At the end of the words, Lin Yu's tone was also full of lightness, as if in his eyes, proving the ns equation was just an easy thing.

After feeling the meaning of Lin Yu's words, the two old men couldn't help but glance at each other, and they were a little speechless for a while.

After co-authoring for a long time, they have now discovered that even the solution of the ns equation is a problem that Lin Yu just came up with temporarily......

After a moment of silence, as if thinking of something, Old Man Chern suddenly asked, "How did you suddenly remember to prove the ns equation?" ā€

"Well, the main reason is that I just remembered that when we build space carriers in the future, we may need to use this equation in some aspects."

In the stunned gazes of the two old men, Lin Yu slowly said his reasons.

Aerospace carriers?

When will Huaxia be able to create something that only exists in science fiction?

Aren't they all aircraft carriers now!

The two old men glanced at each other, both a little dazed.

In a trance, they suddenly had the illusion that they might not be in the same dimension as Lin Yu.

As time passed, there were more and more people in the lecture hall, and after a while, the entire lecture hall was full.

As the five top mathematicians in the Princeton Department of Mathematics, Deligne and other five people also sat down one after another.

After everyone was seated, the moderator of the report meeting walked up with a smile on his face.

Suits, ties, leather shoes, and meticulously groomed grease heads.

This is a handsome blonde man with a gentlemanly elegance.

After a brief introduction by the moderator, the presentation will officially begin.

Lin Yu's report will be on the second station, and the time will be two hours in total.

And when Lin Yu's report meeting ended, the time was exactly around noon, and the remaining more than an hour was enough for all of them to catch the plane.

Soon, under the brief introduction of the host, the first report meeting officially began.

An old professor who was a little bald slowly stood up, nodded to everyone present, and then walked unhurriedly to the lecture table where the whiteboard had been prepared.

"The title of my talk is Function Space Topological Consistency Problems." The old professor stood on the stage and said lightly.

After hearing the old professor's words, four words came to mind in the minds of everyone in the lecture hall.

Topological functions!

The topological function covers a wide range of areas, and it can be said that it encompasses most areas of mathematics as a whole.

Moreover, because of its great difficulty, it has always been called the most difficult fortress in the mathematical community by mathematicians.

However, the old professor in front of him was staring at it.

At this moment, everyone came to the spirit, and looked at the whiteboard on the report table one by one.

Under the gaze of everyone, the old professor calmly picked up the black marker, and began to write on the whiteboard, while slowly speaking: "X is a topological space, a(x) represents its open set lattice, topological space x is nuclear-tight, if and only if Ī©(x) is a continuous lattice, usually we think that a topology is tight is to say that it is lawso tight......"

"So, for continuous depol, we have some basic properties.

1. Insertion property, xy∈l, x

Later, as more and more mathematicians took inspiration from the sieve method.

There are more and more types of sieving methods, such as the three major sieving methods, generalized screening methods, and so on.

For a problem like the Navier-Stokes equation, there are usually 2 ways out, one is the mathematical method, and the other is the computer calculation.

However, now in mathematics, there is no good way, if it is computer calculation, then the difficulty is that the amount of calculation is too large,

Because, it's like supposing that a fluid with an edge length of 1000 is represented by a small cube with an edge length of 1.

In this way, there will be 1000^3 = 1 billion small cubes.

To calculate the mutual adhesion force between each cube, this is equivalent to an n-volume problem, n = 1 billion.

So, it's unfair to think of the Navier-Stokes equation as a mathematical problem.

Because this cannot be solved mathematically, and mathematically it is the delicate work of embroidery, not such a rough calculation.

Therefore, for Lin Yu, if he wants to successfully derive the Navier-Stokes equation, he can only rely on the sieve method and his own computational amount comparable to that of a superbrain.

And that's exactly what Lin Yu thought.
