Just like the mathematical community, which has been boiling over by the Riemann conjecture, the Klinthia Hotel, where the IMU conference is being held, is like a microcosm of the entire mathematical community, where people can hear voices talking about it everywhere.

Originally, this IMU conference was still stained with a heavy haze because of the sudden change, but in the face of Riemann's conjecture of this century, no matter how large the haze, it seems to be insignificant......

"Have you heard? The Riemann conjecture was proven! ”

"Really? It's not going to be the same oolong as last time, right? This is already the first person to claim to have proved the Riemann conjecture. ”

"All I can tell you is that it's probably two digits, maybe three digits...... But this time it's different! The author of the paper is Professor Lu! It is said that inspired by Ms. Vera Puyuil's 45-minute presentation, he finally completed the final step of proof! The paper was already hung on Arxiv by him yesterday...... God, you haven't heard of the whole discussion of mathematical interpretation now? ”

"I can't believe it! Riemann conjecture...... Do you think if he proves it, will the International Union of Mathematicians make an exception and award him two Fields Medals? ”

"There is no doubt that Riemann is worthy of such glory...... But what's the point? If he really proves the Riemann conjecture, why don't we just set up a separate award in his name? ”

"I heard that the afternoon was his 60-minute presentation...... I see, no wonder he scheduled his presentation for the last session of the IMU conference. ”

"Do you think he will change the content of the briefing on an ad hoc basis?"

"I don't know! But I can be sure that if I miss this presentation, it will be a loss for the rest of my life! ”

There was a lot of talk in the hotel.

Whether it's a café, a restaurant, or an executive lounge, there's a discussion about it everywhere there's a lot of people.

At present, no one in the academic community has expressed a position on the content of this paper, and the vast majority of people have not even finished the paper.

Therefore, for those who are following the progress of this matter, but do not have the ability to gnaw on the paper, the importance of the 60-minute presentation in the afternoon is particularly prominent.

Regardless of whether Lu Zhou will temporarily change the content of the report meeting, it is certain that since he chose to release the paper at this time, he will definitely not say a word about the paper......

On the other side, the hotel's café.

Through the layers of relationships in the Chinese mathematics community, it took a lot of effort to finally get in touch with Lu Zhou's student, Qin Yue, who teaches at Princeton, and Academician Wang Shicheng, who invited him to the café to meet, and said in an anxious tone.

"Have you met Professor Lu? I haven't been able to find his person for a long time, and I can't find his room number, do you know where he is now? ”

If it weren't for such an accident, Wang Shicheng would not have been willing to meet the guy he hated.

However, now, not for himself, but for the future of the Chinese mathematical community, he has to meet that person.

Looking at Academician Wang Shicheng with an anxious face, Qin Yue hesitated slightly and said.

"No...... But I think he should be in the hospital. ”

Wang Shicheng was stunned, obviously not expecting such an answer.

"Hospital?"

Qin Yue nodded and said, "Well, Miss Vera Puyuyi is his most proud student. ”

"He was actually in the hospital at such an important moment......" Wang Shicheng paced back and forth, stomped his feet after a few turns, and finally sighed heavily, shook his head and said, "Hey! Forget it, it's too late to pass now, and the afternoon report meeting will begin. ”

Looking at the old gentleman with a puzzled expression, Qin Yue pushed down his glasses and said.

“…… Is there something wrong with you? ”

Academician Wang Shicheng's eyes widened and said: "This is related to the future of our Chinese mathematics community, can this be okay?" Now that the whole world is paying attention to this matter, we have to ask how sure he is. ”

Qin Yue thought for a while and said, "If you're worried about this...... I don't think it's necessary. ”

Wang Shicheng was slightly stunned for a moment and said, "...... What do you mean? ”

Qin Yue continued in a serious tone: "If the professor's words were not 100% sure, he would not release an obviously controversial academic achievement. ”

"So, if you ask him how sure he is, there's no need at all."

"For him, he must be 100% sure that he will hang the preprint on Arxiv."

……

It's not just the hotel that's talking.

The entrance of the Klingthia Hotel is already crowded with broadcast vehicles from major media outlets.

While mathematics is a distant topic for the general public, the Riemann conjecture is different.

The passage of time, the legends surrounding it, and the million-dollar prize money all give it a very different meaning than the usual mathematical puzzles.

Just like Professor Wiles, who was in Time magazine in the first place.

If anyone does succeed in proving the Riemann conjecture, there is no doubt that his photograph will not only be on the cover of Time magazine, but will also be one of the most outstanding mathematicians of the century.

Even though the 21st century has only just passed a fifth.

Reporters with long guns and short guns tried to rush into the hotel, but unfortunately they were stopped by a big man standing at the door.

"We're BBC reporters, here's my press card, please let us in!"

"This is the Federal Security Service, and we've been ordered that no one will be allowed in except academics who have been invited to the conference. If you would like to enter, please contact the organizing committee to get an entry. ”

"We'll contact the Organizing Committee of the General Assembly later, in fact my assistant is already doing this, please do well, let's go in first, now the whole world is waiting for the result of whether the Riemann conjecture has been proven."

This sentence obviously did not impress the security guard standing at the door, and the burly and tall Russian just threw out an unkind refusal.

"It's none of our business."

In addition to reporters, there were also scholars who had traveled thousands of miles by plane to block the door.

In fact, this year's IMU conference is coming to an end. As soon as the closing ceremony is over tomorrow and the venue for the next conference is announced, scholars from all over the world will be returning to their respective homes, and it is obviously too late to come to the IMU conference now.

However, these scholars did not come for the IMU conference.

Compared to tomorrow's inconsequential closing ceremony, the upcoming 60-minute briefing is what they really care about......

Dragging his suitcase to the door of the hotel, Professor Tao Zhexuan, who finally squeezed in from the crowd, quickly passed the security check procedure, and walked into the hotel while sorting out his crooked collar.

Although he did not sign up for this IMU conference, a scholar like him who is very knowledgeable and well-connected has no problem saying hello to the organizing committee of the conference and getting an empty room.

Thankfully, however, he had done it early, and by the time he sent the email to Professor Holden, it was said that by the time two days later there were only two empty rooms left.

And the day before that paper was hung on Arxiv, that is, yesterday, the number was still in double digits......

I happened to pass by the lobby of the hotel and saw Professor Tao walking in through the door, and Professor Peverman's face immediately showed a look of surprise.

"You're here?"

From Los Angeles to St. Petersburg, that's not that close.

In a natural tone, Tao Zhexuan smiled and said, "Of course, how could I miss this kind of thing." ”

After settling down and glancing at the computer bag he was carrying, Professor Feverman continued: "I guess you have already read the paper on the plane, and you should have studied more about number theory than I did, I am curious...... What did you think of that paper? ”

Tao Zhexuan shook his head and said: "There are a few doubts, I don't particularly understand the core argument part, the time is too short, the flight is only more than ten hours, and I still have to adjust the time difference...... It's the damn jet lag that makes me just want to doze off now, and hopefully I won't fall asleep for a while. ”

Professor Feverman smiled and said, "Can Professor Lu's speech make you fall asleep?" ”

Slightly stunned, Tao Zhexuan then smiled and touched the back of his head.

"That's right."

If this kind of crucial moment that determines the future of mathematics can be asleep......

There is no need for others to say, he himself has to admire his nerves.

After greeting Professor Feverman, Professor Tao was about to go to the front desk to check in, when he suddenly caught a glimpse of an unexpected figure from a corner of the lobby.

I saw that the middle-aged man with a beard, sparse hair, and even a funny draped back, was explaining something to the hotel staff. Perhaps because his maverick appearance was really incompatible with the atmosphere here, the security guards next to him frequently cast a vigilant gaze at him.

Noticing the surprised expression on Professor Tao's face, Professor Feverman asked curiously.

"What's wrong?"

“…… Nothing, just a bit of an accident. ”

After settling down, Tao Zhexuan withdrew his gaze from there, looked at Professor Feverman and said with a smile.

"Sure enough, it's still our Professor Lu who is attractive."

"I didn't expect that person to come."

……

The presentation will begin in an hour.

Lu Zhou, who came back from the hospital, locked himself in his room.

Now the entire Klingthia Hotel is shrouded in a huge aura.

Almost all the world's top scholars have their eyes on the IMU conference in St. Petersburg, either already standing in person or on their way......

And it's not just the attention of industry insiders.

The discussion about the paper has long since spread from Mathoverflow, an academic forum for industry insiders, to Twitter, Facebook, and social platforms for the general public.

Whether it is a serious discussion or a joke with an entertaining spirit, there is no doubt that the whole world is now watching this matter and whether the proposition of the century has been answered.

If you are an ordinary person, in the face of this huge pressure, it is probably not easy to maintain normal breathing and heart rate, and adjust your mentality when you go on stage.

But for Lu Zhou, who is used to seeing big scenes, it feels like that.

Perhaps for the mathematical community, whether the Riemann hypothesis has been proven may be debated, and it will take time for the entire academic community to accept his paper.

But for Lu Zhou himself......

Since even systems from the future or higher civilizations have judged his proof to be logically self-consistent, he is not particularly concerned about whether others can understand his process.

What's more, there is one more important thing waiting for him to do.

Standing in front of the floor-to-ceiling window of the room, overlooking the media broadcast van that filled the hotel door downstairs, Lu Zhou took out his mobile phone and called Chen Yushan, who was far away in China.

"Hello? Something, suddenly thought of talking to me on the phone. ”

Lu Zhou thought for a while and said, "How much is my deposit?" ”

Hearing this, Chen Yushan was slightly stunned, and then said with a headache.

“…… How do I know if your deposit is on your account? However, if you're asking about the company's funds, I can ask the accountant to make a copy—"

"Can you get 100 million?"

“…… I suspect you're kidding me," Chen Yushan said speechlessly, "If you want to say that one billion in liquidity, I'm afraid it's a little troublesome, but if you can't get one hundred million...... You've got me fired. ”

As soon as he heard this, Lu Zhou subconsciously said, "...... How can that work. ”

He doesn't run a company.

Without the help of a trusted person, many things can get troublesome.

Hearing Lu Zhou's knee-jerk reaction, the corners of Chen Yushan's mouth turned upward, and she leaned back on the office chair in a good mood and said.

"Tell me, I guess you're going to have something to trouble me with again. I'm also curious about what it means to spend so much money all at once. ”

“…… It's not like you have to spend so much money all at once. However, this is a real problem. ”

It took about five minutes for Lu Zhou to explain what he was thinking.

After listening to what Lu Zhou said on the phone in a daze, it took Chen Yushan a while to digest this huge amount of information.

"I kind of understand what you mean...... That student, it's important to you. ”

Lu Zhou: "Well, this method may sound a little crazy, but this may be the only way to save her." ”

After being silent for a while, Chen Yushan sighed and said.

"I see, I'll do as you say. As for whether it can be successful......"

Lu Zhou: "Don't worry, I have the technical side of things." ”

After making this call, Lu Zhou then made several more calls, some to acquaintances at Shangjing 301 Hospital, and some to the Institute for Advanced Study.

Explain the situation as concisely as possible, just when Lu Zhou hung up the last phone, there was a knock at the door.

walked up and opened the door, only to see that the young man who took him to the No. 7 lecture hall a few days ago was standing at the door with a restrained face, looking at him and saying respectfully

"Dear Professor Lu Zhou, Professor Holden asked me to inform you that your presentation will start in thirty minutes, and if you are ready, I recommend that you go at least fifteen minutes early."

Glancing at the time, Lu Zhou thought that it was almost time to pass, so he nodded.

"I see."

"Since it's almost starting, let's get over now."

The sooner this matter is resolved, the sooner you can hit the road.

Sixty-minute presentation.

I believe it should be enough.
