The morning of the fifth day of the academic exchange meeting.

A man in a suit walked quickly to the door of room 306 and politely reached out and knocked on the door.

"Mr. Lu Zhou, your report meeting is about to start, is it convenient for you now?"

There was a noise in the room.

Immediately after, a voice came out.

"Now? Won't my presentation be afternoon? ”

The man in the suit had a subtle embarrassment on his face, coughed softly, and continued: "An hour later, due to a small accident, a Belgian reporter temporarily withdrew the paper due to travel problems, and our lecture schedule was temporarily adjusted...... Haven't you looked at your mailbox? ”

There was silence in the room for a moment, and an impatient sigh was heard.

“…… Wait for me to take a shower. ”

The conference staff member breathed a sigh of relief.

"We apologize for the inconvenience...... Also, please don't wash it for too long. ”

……

In the No. 1 lecture hall, a room slightly larger than the lecture hall of Jinling University, there were about two or three hundred people sitting in the audience. Among them, there are little-known small people, and there are also big bulls in the academic world.

For example, Professor Pierre Deligne, the protégé of the late emperor of mathematics Grothendieck, and Professor Wang Xiping from Yenching University......

may be because of his poor mental state, Lu Zhou, standing on the podium, was unexpectedly calm, without the slightest nervousness, or stage fright above this.

Straightening the microphone, Lu Zhou sorted out his speech ideas, and after seeing the "can start" signal given by the staff of the conference group, he slowly spoke.

"Everyone should have read my paper, and according to the arrangement of the conference affairs group, the content of today's report should be the study of the distribution law of Mersenne primes...... However, due to the arbitrary schedule of the conference affairs team, the report that should have been held in the afternoon will be moved to the morning, so please allow me to make a small wayward request. ”

After a pause, Lu Zhou looked at the conference team staff next to him, "Can you help me hang a whiteboard on it?" ”

The staff of the conference team was stunned and hesitated: "No problem, but the projection effect of the projector on the whiteboard is very poor, and the people behind may not be able to see it." ”

"Just give me another pen," Lu Zhou glanced at the projector, "This thing can be turned off." ”

Many people in the audience were talking about each other, not knowing what Lu Zhou was going to do.

The staff of the conference team were also curious, but it was clear that they had not encountered the stranger requests of the "geniuses" once or twice, so they quickly complied, dragging a whiteboard from the classroom next door.

Taking over the marker from the staff of the conference affairs group, Lu Zhou nodded and said "thank you", then turned to face the whiteboard, took a deep breath, closed his eyes and entered the system space, opening the enlightenment time.

The last hour.

He will be here, to complete the final proof!

Opening his eyes, Lu Zhou raised his pen.

On the whiteboard, write down the first line of the equation......

Just when Lu Zhou meticulously wrote down the proof process, the atmosphere in the venue was a little restless.

Forget it without saying a word, and don't even put PPT, which is really unfriendly to those rookies who participate in academic conferences for the first few times.

The two student-looking people sitting in the back row packed up their things and quietly left.

The duration of the academic conference is only a few days, and there are only a few lectures that can be listened to, and these 30 minutes are very important for the presenters and the people who listen to the lectures.

As for those who often participate in various academic conferences, they have seen a lot, and the expressions on their faces have not changed. They focused on what the reporter was doing, not on the reporter himself......

When Lu Zhou wrote the tenth line of the equation, Professor Deligne, who was originally expressionless, suddenly raised his eyebrows.

The crossed legs changed positions, looked at the teaching assistant next to him, and he whispered, "Do you have a notebook?" ”

The teaching assistant was stunned, and quickly took out the notebook and pen, "Take it." ”

"Thank you."

With the notebook resting on his lap, Deligne stared at the lines of arithmetic on the whiteboard, his eyes becoming serious.

At the same time, sitting on the other side of the venue, Mr. Wang Xiping was also staring at the whiteboard.

Although he is old, even with glasses, it is not so easy to see things on the whiteboard, but he still looks very carefully and carefully.

Sitting next to him was the academic exchange group of Yan University, composed of three undergraduates, one graduate student and one doctoral student, including students he brought and his old friends entrusted him to bring them out to see the world.

Staring at the whiteboard directly in front of him, Wei Wen frowned and said, "Sieve method? What does he want to do? ”

Oh, yes.

What does he want to do......

Mr. Wang is also thinking about this problem.

But when he saw the tenth line of the equation, his cloudy eyes instantly narrowed, and then he opened a trace of disbelief.

Seeing this, he probably guessed.

But I couldn't believe it......

He's going to challenge the world's problems here? Proving the twin prime conjecture!?

Either crazy or crazy......

“…… Sieve method? Is he proving the second formulation of Goldbach's conjecture? No, no, this step ......" Molina stared at the whiteboard, the tip of her pen poking into the notebook in her hand, her sapphire pupils glinting with disbelief...... Professor Zelberg's paper published in the Annals of Mathematics in '95 on the complementary study of topological methods to sieve theory...... He's challenging the twin prime conjecture! ”

By the time Lu Zhou wrote the twentieth line of the equation, 30 percent of the people in the room had already understood what the speaker on the stage wanted to do.

As for the rest, it doesn't matter if you can't read it.

This kind of academic conference itself is open-ended, the difficulty is only to pass the report paper and be invited, there is not too high a threshold for registration, it is better to say that the organizer is eager for you to come and send money, after all, the registration fee is not cheap.

And if you take 10,000 steps back, it doesn't matter much if you don't sign up.

This kind of semi-open academic conference, although the conference team has issued admission passes, but when you come to listen to the lecture, you don't check this thing. Therefore, many people who did not sign up did not prevent them from coming to listen to the report and discuss math problems with the "stall owners" of academic posters.

The only difference was that they couldn't put up their own posters, stay in the chartered Princeton Hotel, and attend the first and last day of cocktail parties.

Wei Wen, who was staring at the whiteboard and holding the pen tightly, suddenly said in a loud voice: "Vinogradov's three-prime theorem? ”

Professor Wang Xiping nodded: "Yes." ”

Wei Wen couldn't help but ask, "Professor...... What the hell is he trying to do? ”

Professor Wang Xiping smiled: "Hehe, can't you see it?" ”

Wei Wen looked solemn and shook his head.

"Then read on." Professor Wang Xiping sighed, looked at the whiteboard on the stage, nodded approvingly, and sighed softly, "It seems that this old Tang has brought out a good seedling...... The next 20 years can be looked forward to. ”

He didn't notice the movement in the venue, Lu Zhou's attention was all focused on the whiteboard, and the speed of drawing one stroke at a time in his hand was not fast, but he was extra cautious and extra hard.

As the minutes passed, the staff of the conference affairs team standing on the side kept looking at their watches.

Finally, with five minutes left, the staff member in the suit coughed and routinely reminded him when he saw that the QA session had not yet begun.

"There are five minutes left, please limit the time for the speaker to speak."

Lu Zhou stood unmoved in front of the whiteboard, writing with the marker board in his hand, as if he hadn't heard it.

He has completely blocked out external interference, and he may not even be able to listen to Chinese reminders at this time, let alone English that has to be translated by the brain.

Finally, another five minutes passed.

The two conference staff exchanged glances, ready to go up to the stage to remind the speaker who had forgotten the time and occasion.

However, just as one of the staff members took the stage, a voice that was not loud but clear came from the first row of the venue.

"Let him continue."

The one who spoke was Pierre Deligne.

Seeing this big guy, the staff subconsciously coaxed.

However, out of duty, he still looked embarrassed and explained to the big guy: "But the next report will start soon......"

Putting his notes aside and slowly standing up, Professor Deligne looked back behind him and said slowly, "The next lecture will be temporarily relocated to Alternate Lecture Hall 4, and those who want to listen to the next one can go over first." ”

The voice fell.

Ten seconds passed, and no one moved.

No one wants to move either.

Those who can't understand it have already left the scene and will not sit until now.

And the rest of the people can not only understand what the reporter is doing, but even have seen some doorways.

Challenging world-class mathematical conjectures at the presentation?

Anyone who dares to do this is either a genius or a madman!

If what is going to happen next is not a big joke, then they are witnessing a great moment when they are sitting here at this moment.

And either one, it's a cool thing for the "arrogant" Princetonians......
