Lu Zhou's guess was indeed correct.

Xiao Ai did upload the paper successfully five minutes ago, and the system's prompt sound came at about that time.

It's just that although the paper is uploaded, it's probably not so easy to see the paper at this time.

Because it's almost in those five minutes......

The servers of the Arxiv website have been completely paralyzed!

Originally, an academic website like this usually does not have a large number of visits, and considering various factors such as operating costs, it will not set up a server with a particularly large capacity.

Now, however, mathematicians in almost all parts of the world, as long as they set a tag to track the Riemann conjecture, have all received alerts from messages on their websites or even in their mailboxes.

It happened that it was 9 o'clock in the morning in North America, and it seemed that in an instant, most of the world's mathematicians—even scholars who were not engaged in mathematics at all, but who were just rubbing a little bit with mathematics, all ran to download papers.

Before the administrators of the Arxiv website could figure out what was going on, they were completely stunned by the number of DOS-like visits.

Then, the server went on a glorious break.

Almost at the same time that Arxiv's website went down, the discussion on the topic was completely blown up on Mathoverflow, a math forum for global industry insiders.

[Proof of the Riemann conjecture!? Did you read that push message on Arxiv?! 】

[Look at the yarn!] The websites are all down, look at the ghost! 】

[I was lucky enough to see it, but not in the push message, I saw it in the list of my tracking tags...... And I suspected at one point that I was wrong. 】

[God, I went to see the calendar!] Today is not April 1st! 】

[Is there anyone who has already finished reading the paper?] Come out and tell me what exactly is said in the paper? Did he prove it? 】

[This is beyond the scope of my field of study, but when I look at Professor Tao's dynamics, he seems to have printed the paper.] And looking at his class schedule, it seems that the next whole week of classes and meetings have been withdrawn. 】

[Wait, he's not at the IMU conference? I mean he didn't go to St. Petersburg? 】

[I didn't go this time, and it is said that he regrets it. 】

Professor Tao is not the only one who regrets this.

In fact, many scholars who did not attend this mathematician conference for various reasons are beating their chests with regret.

How did you just catch up with this session?

How did they catch up with the one they didn't go to?

Two days later, it was Professor Lu's 60-minute presentation, and the topic happened to be the research on the Riemann hypothesis.

Many people's intestines are repentant!

At the same time, the executive lounge of the Klingthia Hotel.

In the corner by the window, two well-known mathematics professors sat in a low-key manner.

One of them was Faltins, and sitting across from him was Deligne.

The two were drinking coffee and chatting about the future of mathematics.

“…… What happened to Miss Puuyi was a pity, and it was a heavy blow to the entire mathematical community. Before coming here, I had planned to invite her to join my plans, but I didn't expect this to happen. ”

"There are unpredictable circumstances in the sky, and people have good and bad luck...... There seems to be such a proverb in Huaguo. We can only pray that she will suffer less in the few days that are missing. ”

After a pause, Professor Deligne, who sighed softly, glanced at Faltins and diverted the heavy topic, "Speaking of which, you are too old to be idle. ”

"It's because I'm at this age that I want to leave something behind before I retire completely...... Seriously, I kind of understand Sir Attiyah now. ”

Professor Deligne gave him a noncommittal look and did not answer.

There have been so many sad things lately, and he really doesn't want to touch those topics that have already been sad.

At this moment, footsteps suddenly came from the door of the executive lounge.

I saw Professor Feverman walk over from there with a dejected expression on his face.

It was a bit like a fright, but not like something terrible had happened.

Seeing the expression on his face, Professor Deligne raised his brow slightly, and was about to ask him what was going on, when he saw him speak consciously.

And as soon as he spoke, everyone's movements stopped.

"The Riemann conjecture was proven."

The air fell silent for a moment.

It's as if a needle falls on the ground and can be heard clearly.

Professor Faltins didn't even look up, and said lightly, "This can't be. ”

Professor Deligne, who was also expressionless, shrugged his shoulders and said, "This joke is not funny at all. ”

As if knowing what the two would say, Professor Feverman had no surprise on his face, except to add to Deligne: "It's your students who prove it." ”

This time, the expressions on the faces of the two people who were sitting there calmly changed instantly.

Professor Faltins, in particular, opened his mouth dumbly, and this time he finally raised his head, frowned, and said.

“…… You mean Lu Zhou? ”

"Yes." Professor Feverman nodded, and said in a natural voice, "I don't remember any other students of mine from my old friend who were studying this direction. ”

“……”

Hearing this "yes", Professor Faltins stopped speaking for a moment, and just turned his gaze to Deligne, as if waiting for his opinion.

However, Professor Deligne also had a stunned expression on his face at the moment, and even a little unexpectedly confused.

Opening his mouth, he raised his slightly trembling index finger and touched the glasses on the bridge of his nose, straightened it, and looked at Professor Feverman standing at the door and said seriously.

"Are you sure he said that?"

Recalling the scene he had seen in the lecture hall earlier, Professor Feverman sighed softly.

"I don't need to be sure at all, he has uploaded the paper to Arxiv. If you've ever signed up for Mathoverflow, you'll be able to see that the whole mathematical community is talking about these things, and as far as I know, there's already a math institute working on a preprint of him hanging on Arxiv......"

Taking a deep breath, his shoulders leaning back in his chair gradually relaxed, and when he learned that the preprint had been hung out, Professor Deligne was in no hurry to confirm the paper on Arxiv.

The same was true of Faltins, who sat across from him.

The old man, whose shock was not inferior to him at this moment, just looked at him in silence before speaking.

"I didn't expect that we would witness history by accident."

There was silence for a long time before Deligne let out two hurried sighs from his closed mouth.

“…… Oh, yes. ”

"It was so sudden."

It is no exaggeration to say that if the Riemann conjecture was really proved by him. The history of mathematics in the 21st century is at least ten pages less because of its existence. And the textbook on analytic number theory has to be at least twenty pages more than that.

Of course, all this is premised on the fact that he is indeed right.
