After ending the call with Tao Zhexuan, Xu Chuan put down his mobile phone and looked at the manuscript paper on the table and breathed a sigh of relief.

Whether the Riemann conjecture can be solved, he actually has no bottom in his heart.

After all, the Riemann conjecture is the most difficult problem in mathematics today, at least, it should be the most difficult and influential of the seven millennial problems.

Since Riemann put forward this conjecture in the middle of the 19th century, after more than 150 years, there are still not many breakthroughs in Riemann's conjecture, and there are not even many achievements close to it, which shows how difficult it is.

Of course, the length of a conjecture's existence alone does not fully explain the difficulty, value, and influence of a conjecture.

For example, Goldbach's conjecture, known as the crown jewel of mathematics, has been proposed for almost 300 years, and no one has yet solved it.

But when the mathematical community selected the seven major problems of the 21st century, it did not include them.

Riemann guessed that he really wasn't much sure he could solve it.

But......

Looking at the manuscript paper on the desktop, the corners of Xu Chuan's mouth raised an arc with a smile.

Although he is not sure to solve the Riemann conjecture, he can still make a breakthrough in it and weaken it to solve some problems!

Although it is not yet started, there are still many problems that need to be solved.

But at least, a complete line of thought was constructed by him at this moment.

The rest is to follow this line of thought.

Xu Chuan didn't know how far he could go, but he knew very well that compared to the current research on the Riemann conjecture in the mathematical community, this time would definitely be a huge breakthrough!

Because, when 0

......

For Xu Chuan, locking himself in the villa to study the Riemann conjecture can actually be said to be a very 'cool' thing for him.

Especially in this kind of major breakthrough, he can get far more pleasure than doing something else outside.

But for others, Xu Chuan's not going out is a big deal.

Not to mention the rest, the Xinghai Research Institute is about to turn the sky upside down.

The establishment of the lunar biosphere project and the lunar scientific research outpost base is still waiting for Xu Chuan to preside over the work.

Although Xu Chuan had already arranged most of the work before this, the work in the aerospace field was presided over by Academician Chang Huaxiang and Weng Yunzong, and other research institutes did not have much other important work except for the development of second-generation controllable nuclear fusion technology on the energy side.

But many times, he, the person in charge, is not there, and some key matters are not easy for Chang Huaxiang or Weng Yunzong to decide, and even the space bureau cannot deal with them directly.

For example, several middle-aged men from the Middle East who came from the Middle East wearing white robes, turbans and beards have been waiting here at the Xinghai Research Institute for several days.

Regarding the arrival of representatives of these countries in the Middle East, not to mention the high-level of the Xinghai Research Institute, even the space agency is not very clear.

Although the construction of the lunar biosphere project has been finalized and countries around the world will be invited to participate, the relevant work is still being arranged at the top level.

The representative of the Middle East was invited by Xu Chuan's assistant.

Now that the other party is here, he has gone to something else, which is really head-catching.

......

At the foot of the Purple Mountain, in the villa complex.

Because of Xu Chuan's relationship, the security of this villa complex at the foot of the Purple Mountain has been improved a lot, with 360-degree monitoring without dead ends, and security in the open and in the dark, layer after layer.

It can be said that even if a fly flies in, they can figure out the male and female at the first time.

Zheng Hai stayed in another small villa next to him, looking at Xu Chuan through the fence, holding a cigarette with only the butt of the cigarette left in his hand, squinting and basking in the sun.

This is not the first time he has done this, when Xu Chuan was studying mathematical problems, he basically rarely went out, as short as a few days, as long as several months, and as a personal driver + bodyguard, he basically had no work during this time.

At the same time, in addition to checking his work every day, he either went to train to maintain his physical fitness in the rest of the time, or sat in the villa in the general control room in charge of security and smoked a cigarette and waited for Xu Chuan to get out.

"Professor, he hasn't come out yet?"

In the villa, another woman walked out and asked Zheng Hai, who was basking in the sun in the courtyard. It was Xu Chuan's life + medical assistant Tang Sijia who came out.

She glanced at the villa not far away, and a trace of worry flashed in her eyes, she had been in the room for almost a week, and she hadn't even left the door, which couldn't help but make her feel a little anxious.

Zheng Hai didn't look back, lazily basking in the sun, raised his right hand to smoke the only little cigarette butt left in his hand, and then threw it into the trash can on the side, and spit out a word in his mouth.

"Nope."

"And when will he come out?"

Zheng Hai squinted, looked at the villa not far away, and said, "I don't know."

Tang Sijia: "...... I don't know what the hell it is?

Zheng Hai thought for a moment and added, "When he solves the problem he is studying, he will come out."

This is not the first time he has encountered this situation, when Xu Chuan studied the NS equation before, he had nested in the villa for more than a month.

It's the assistant who was arranged later, and it's really the first time I've encountered it, and it's normal to be a little anxious.

Listening to Zheng Hai's words, Tang Sijia walked around the courtyard with some distress.

She knew very well what Xu Chuan was doing in the villa, but she couldn't do this with research problems.

Staying in the villa all day, it is estimated that I am staying up late every day, this short time is fine, in the long run, where can the body resist?

But she couldn't help it, she didn't listen to her at all.

When she came out of the military academy, she met such a master when she took on the task for the first time, and she felt that her life assistant and medical assistant were about to die in name, and the other party didn't care about her opinion at all.

It's a big head.

In the small courtyard, Tang Sijia sighed.

e=(′o'*))))Alas, the work of this life assistant is almost out of work......

When Tang Sijia and Zheng Hai were silently looking at the villa where Xu Chuan was, Zheng Hai's mobile phone in the courtyard suddenly rang, breaking the silence.

Zheng Hai quickly took out his mobile phone and connected the phone.

"Hey, Zheng Hai, I'll take me to the Xinghai Research Institute in ten minutes."

didn't wait for him to reply, and hung up on the other end of the phone.

Zheng Hai didn't care, put the phone in his pocket and stood up.

"What's wrong?" On the side, Tang Sijia asked.

Zheng Hai: "The professor came out."

Hearing this, Tang Sijia looked over in surprise and asked curiously, "He solved it?"

Although she has not experienced much of Xu Chuan's retreat to study the problem, she also has an understanding of that person's character, and if she goes out while studying the problem, she will either solve the problem or deny this path.

As for the rest, it can be said that there are very few things or things that can shake him.

Zheng Hai shook his head and said, "How do I know,

I don't know math, and the professor didn't say anything."

He really doesn't understand mathematics, and he doesn't know what Xu Chuan is studying, but according to his past experience, this person probably has a way of thinking when he chooses to go out.

After all, if he doesn't solve the problem or sort out his thinking, he basically won't come out, and no matter how important things are.

However, there is no need to say that this kind of judgment can be done, whether it can be done or not is the professor's business, and it has nothing to do with him, they just need to do their own work.

......

Ten minutes was not a long time, and soon, the iron fence gate of the courtyard suddenly creaked open, and Xu Chuan, who was wearing a white T, walked out of the room.

"Go to the Xinghai Research Institute."

Pulling the car door, Xu Chuan sat in and said to Zheng Hai in front.

"Okay."

In response, Zheng Hai didn't ask much, and started the car and rushed towards the Xinghai Research Institute.

In the back seat, Xu Chuan took out his mobile phone from his pocket and flipped through the information.

He also studied the Riemann conjecture for a while, and although it was said that the communication with the outside world was not interrupted during this time, he did not read the news most of the time.

It just so happens that this will take some time in the car, so you can simply tidy it up.

As for the quasi-Riemann conjecture, although it has not yet been proven, he already has the ideas and methods, so there is no need to be in a hurry.

On the contrary, the representatives of the countries in the Middle East that asked Assistant Qin Yue to contact him before have already arranged for them to come over.

The amount of money needed to build a biosphere project on the lunar surface is enormous.

With the simultaneous opening of a number of 100-billion-level projects such as manned spaceflight and large strong particle collider, coupled with various infrastructure projects in China, it is difficult for China, even if it is the world's largest country in terms of economic aggregate, to draw a large amount of money to carry out another super project.

After all, there are many places to spend money.

But those parts of the Middle East are different.

Although the price of oil has plummeted with the realization of controlled nuclear fusion technology, it is not worth the fact that other people have mines at home.

No, other countries have mines at home, and countries such as Saudi Arabia, Qatar, and the United Arab Emirates in the Middle East have their own mines, and they are so outrageous that oil can come out of just digging and digging.

It can only be said that even if the price of oil plummets, people are still rich.

......

Although Jinling in September has officially entered autumn, it is one of the hottest months of the year.

The autumn tiger exudes a scorching temperature, baking the city of steel and iron bones.

Getting off the Hongqi car, Xu Chuan walked towards his office.

"Professor, you're here."

In the assistant room of the partition, Qin Yue, who was busy with his own work, quickly stood up and said hello after seeing Xu Chuan.

Xu Chuan nodded and said, "Well, the representative from the Middle East is still there, right?" How long will it take for Director Wu of the Space Administration to arrive?"

Although he needs to find funds for the support points of these large families in the Middle East, he also does not want to have a relationship with a group of people.

This time he was interrupted to study, mainly because the group of big dogs in the Middle East wanted to meet him, plus he was invited by him, and he didn't think so much about it at the beginning, otherwise it would be best to leave this kind of matter involving international cooperation to the country.

Of course, in this cooperation, he also contacted Director Wu Yuankang of the Space Agency, preparing for a three-way meeting, he came over to show up, and then handed over the rest to Director Wu to deal with.

Qin Yue nodded, and quickly reported, "The representative of the Middle East is currently living in the hotel, and it will take about an hour for Director Wu to come over."

Xu Chuan: "Okay, contact the representatives from the Middle East, I've arrived, and in two hours I'll have a meeting here at the Xinghai Research Institute to discuss the lunar surface project, and trouble them to arrange personnel to come over."

"Okay."

Qin Yue nodded, answered, and then asked, "Is there anything else?" Professor."

"It's gone." Xu Chuan answered, thought about something again, and hurriedly shouted, "By the way, wait

Arrange a few people to help me sort out the papers of the four major journals in mathematics in the last two years, not all of them, just select some valuable ones, and send them to me after finishing them."

"In addition, collect papers and materials about the Riemann hypothesis, which has been published in official journals with an impact factor of 5 or more, or more than 20 citations, and send them together."

In the past two years, his energy has been focused on the application field, but he has paid little attention to the development of the mathematical community, and even the papers, he has little time to read them.

It just so happened that the work in the field of aerospace came to an end for the time being, and he was also studying the Riemann conjecture and had time to turn over some of the past papers.

Qin Yue nodded, and after writing down the work, he asked, "How do you divide the value of mathematical journal papers?" Professor, do you have standards?"

Xu Chuan smiled and said, "You can just look for the math staff at the Academy of Natural Sciences, they know how to deal with it."

In addition to the four major research institutes, there are actually some other departments on the Xinghai Research Institute.

For example, there are not many scholars and researchers in the Institute of Natural Sciences, and some of them even hold positions in the four major research institutes, the purpose of which is to cooperate with the development of the four major research institutes in the application field and analyze related theories.

However, in the past two years, with the absorption and recruitment of talents, the Institute of Natural Sciences has also had a lot of its own talents, and even set up corresponding departments such as mathematics, physics, and chemistry below, which can be regarded as forming its own system.

It's just that there is still a distance between it and the increasingly large four major research institutes.

Xu Chuan is not in a hurry, climbing in the field of natural sciences is not so easy, talents need to be accumulated, and this will develop slowly.

Besides, his current energy is not on this.

When he has time in the future, he will cooperate with the Xinghai Research Institute to get his own journal, which should be able to speed up a lot.
