Outside the stadium.

A short, slightly young Sao Nian was running on the road with a satchel on his back. Judging from his frivolous steps and the pouch on his face, I think he didn't sleep well last night.

However, for whatever reason, he has missed the entrance time, so it is natural that he was stopped by the security guard at the gate of the sports hall.

"Classmate, the gymnasium is closed for two days. Let's play in another place."

Looking at the security guard who stopped him, Jimo explains anxiously.

"I'm not here to play, I'm here to listen to the conference!"

The security guard got to know his colleague next to the station, exchanged a strange look, and then cast a strange look at him.

"Listen to the report? It's been two hours since the report meeting. You're late. "

Zimmer: "please, brother, let me in."

The security guard held out his hand.

"And your invitation?"

"Invitation?" Jimo is slightly stunned, "what invitation letter."

"If all the guests have invitations, no one can put them in," said the security guard impatiently. "If you don't have them, don't waste your time. Even if I put them in here, you won't be able to pass the security check later. It's not the school people who stand guard inside. It's useless to talk about love. You'd better not waste your time. "

“…… I am academician Lu's student! "

In saying this, Jimo inevitably blushed.

After all, this so-called "student" is not the kind registered in the archives, but a verbal promise, which still needs to be quoted.

If it wasn't for an emergency, he didn't want to move out of the land God's name.

But now, I don't care so much.

"Just you?" The security guard at the gate glanced at him with an expression of disbelief. "You're a little older."

Jimo cried and laughed: "freshman But that's not the point! The point is that I'm really in a hurry. I've been late for two hours. I can't hear anything when I go in later. "

just as he was talking, a familiar voice suddenly came from the door.

"What are you doing at the door?"

"Professor Chen?"

Although he is usually very low-key, as a talent dug by Lu Zhou from Yanda mathematics center, Professor Chen is quite famous in Jinling University. At least they are familiar with these security guards.

Seeing the two security guards looking at themselves in surprise, Chen Yang asked a little vaguely.

“…… What can I do for you? "

"No, No."

Seeing the two security guards smile at the same time, Chen Yang then looks at Jimo standing next to him and frowns.

"Hurry in. The report meeting has been going on for a while."

"Ah, yes, yes."

Back to God, Jimo immediately followed Professor Chen.

As he walked through the door, he glanced at the two gaping security guards, raised his eyebrows proudly, and then walked away quickly without looking back.

Catching up with Chen Yang from behind, Jimo asked as he followed him towards the venue.

"That Professor Chen. "

Chen Yang: "what's the matter?"

Jimo is embarrassed to ask: "why do you get up late?"

"I didn't get up late," Chen Yang shook his head. "I didn't sleep last night."

"Not sleeping?!"

Chen Yang nodded his head and said concisely.

"Well, thesis There are still some things I don't understand. I spent a little time. "

Where did it cost a little?!

It's almost two weeks since that preprint came out, OK? Although

make complaints about this, he finally resisted it.

Soon they arrived at the security entrance.

After Professor Chen explained the situation to the security personnel and made a guarantee, Jimo presented his student ID card and made a simple registration. Finally, he was released by the security personnel and followed Professor Chen to the back of the venue.

Before entering here, Jimo was worried about whether there would be no seat or not. But when he came in, he found that there was a little difference between the situation and his imagination.

The seats in the back two rows are only half full. A large group of people do not sit in the empty seats. They all squeeze into the aisle beside the front row and sit on the floor.

Without any intention of going to the crowd, Jimo follows Chen Yang to find a seat in the back row, and then quickly takes out his notebook and looks in the direction of the stage.

However, after a while, he found that he could not understand what the land boat was writing.

“…… The grand unified theory? " Jimo, who has been doing his homework all night, frowned, his eyes full of questions, "no It doesn't seem to be. ""That's right," Chen Yang nodded, looking at the eight whiteboards that had been pushed aside, and after thinking for a while, he said, "a few minutes ago, the explanation of the theory of grand unification should have ended."

"What he's writing now is..."

“…… It should be a standard guess. "

Looking at the contents of Lu Zhou's blackboard writing, Chen Yang's indifferent pupils gradually caught a touch of shock.

His Adam's Apple moved up and down slightly, murmuring to himself.

"Sure enough! My hunch is right It's a standard guess! "

Leng Leng ground looked at him, Ji Mo swallowed saliva, small voice asked.

“…… What premonition? "

Chen Yang: "do you remember the inference 2 of the grand unification theory?"

Remembering what he saw when he stayed up late to brush his paper yesterday, Jimo replied almost conditionally.

"The cohomology of any coefficient can be calculated by the cohomology of z-coefficient!"

"Correct solution!"

Chen Yang nodded his head, and the tone of voice, which was always flat in normal times, was not only filled with shock and excitement, but also a little shiver caused by excitement.

“…… This is one of the core corollaries of the grand unified theory of algebraic geometry! According to it, we can directly deduce that mapping L ^ (n? 2I): AI (x) → an? I (x) is isomorphic (0 ≤ I ≤ n / 2)! "

At the moment of hearing this sentence, Jimo's pupil slightly contracted, and a pair of eyes immediately opened.

Although his academic knowledge and experience are still a little immature, and it is not clear how the so-called "direct launch" is derived, but as the gold medal winner of the IMO competition, plus the usual extracurricular learning, these basic concepts are still clear to him.

Professor Chen's conclusion is just the generalization of hard Lefschetz theorem!

That is, the first part of grotendic's standard conjecture - Lefschetz's standard conjecture!

“…… It's really Professor Lu. "Looking up at the figure on the stage, and the lines flowing along the tip of the pen, Chen Yang's eyes are mixed with the color of shock and yearning." last night, I suddenly thought of the possibility that might exist. I thought about it all the time before I had a clue in the morning... "

However, what he didn't expect was that he racked his brains for a whole night to figure out the way of thinking and put it into the report meeting, but it seemed that he couldn't even talk about the problems.

On the whiteboard, the idea of surging like the river pours down with the flowing strokes. No matter what kind of ravines and difficulties, they are pale and powerless under the sharp edge of the waving.

There is no obstacle to stop it.

You can't even stop it for a few seconds.

So that when the final line formula and the conclusion that haunted him were written down, everything was so natural.

【…… All of the above are available. ]

[mapping L ^ (n? 2I): AI (x) → an? I (x) is isomorphic (0 ≤ I ≤ n / 2)]

[Lefschetz standard conjecture, established! ]The wandering pen finally stopped.

Almost at the moment when the last punctuation was completed, there were many voices of surprise.

Under the guidance of that atmosphere, Professor sanak, sitting in the crowd, couldn't help raising his left hand, rolling up his cuff and looking at the time on the eye list.

"37 minutes...!"

His voice was drowned out by a deafening cry.

I can't believe looking at the stage, he muttered to himself, repeating the name of God's old man.

“…… God, is this still human? "
