In fact, in terms of conscience, the question that Lu Zhou gave to Han Mengqi still had some meaning of persuasion.

Although this is an open-ended question that anyone who has studied this field can answer, in fact it is not that easy to answer.

Because, it is related to a classic problem about the Riemann zeta function.

That is, the transcendent conjecture of the value of the Riemann zeta function at the point of an odd positive integer.

As He Changwen said, this is not something that a layman who has become a monk halfway can solve.

Unless she is really gifted enough to teach herself the relevant knowledge of analytic number theory, collect literature on the Riemann zeta function on her own, and do some research......

But then again, if she was really so talented in the field of pure mathematics, it would not be a loss for Lu Zhou to accept such an apprentice.

In fact, during this time, Lu Zhou has been thinking about a problem.

The "medal" from a higher civilization that he received some time ago revealed to him a rather important message.

That is, as human civilization has been speculating since the exploration of space, human beings are not alone in this universe, and have even entered the sight of other advanced civilizations, but for some reason they have not come into contact with it.

There are many possible reasons for this, whether it is because of spatial distance, or because of the other party's special civilization philosophy or social philosophy, or even because the other party has disappeared in the long river of time, leaving behind only a piece of information tens of millions of years ago......

Either way, the system currently in his hands should have information about this higher civilization buried, and it is likely that it is the only way for him to obtain information about this high civilization.

At present, if you want to crack the secrets of the system, it seems that upgrading all disciplines to LV10 is a hurdle that cannot be avoided no matter what.

In order to upgrade all subjects to LV10, as the upper limit of the level of mathematics in other subjects, it is undoubtedly necessary to upgrade first.

The only trouble is that the experience cap of three million is really hard to fill.

If nothing else, only the Riemann conjecture, the crown of mathematics of this century, is likely to offer such a vast experience.

With the Queqiao raising the capacity of Huaguo's orbit to the moon to a new order of magnitude, it is only a matter of time before both the Moon Palace and the lunar surface research facility are located.

It is precisely because of this that Lu Zhou has extra energy to free up his hands to prepare for the impact of the mathematics level.

Based on his past experience, the research project he is working on will have a high probability of being the target of the next system mission. There's no way to figure out what the probability is, but it doesn't hurt to be prepared.

The day after assigning the task about the Riemann zeta function to Han Mengqi, he stepped on the eight o'clock bell in the morning and walked into the office, Lu Zhou put the laptop on the table casually, asked Assistant Zhao to make himself a cup of instant coffee, and then sat down at the desk to start a new day's work.

Walking to the side of the desk with the misty coffee, Zhao Huan put the coffee cup on the table at the same time, took out a document from under his elbow, put it in front of Lu Zhou, and said softly.

"Professor, after you got off work yesterday, President Xu came over, and he asked me to hand over this thing to you."

What are the minutes of the seminar of the Teaching and Research Group of the Light of Youth Class?

After seeing the words on the cover of the document, Lu Zhou's eyebrows raised with interest, and he reached out to take it and open the title page.

"I'll take the time to watch, you can get busy first."

"Okay, Professor."

Assistant Zhao nodded, turned around and walked to his desk.

Leaning back in his office chair, Lu Zhou briefly went through the minutes of the meeting while sipping coffee.

In general, the work of the teaching and research group is quite smooth, after getting the policy of reforming the pilot, the framework of the "Light of Youth" class of Kim University has basically been built, the specific teaching plan has also been determined in a recent meeting, and the rest of the work is the selection of the first batch of students and the implementation of the teaching work.

Closing the minutes of the meeting in his hand, Lu Zhou cleared his throat, looked at He Changwen, who was sitting at a desk not far away, and was working hard to brush up on the literature, and spoke.

"Changwen, I'll give you a task."

As soon as he heard Lu Zhou's call, He Changwen, who was brushing his paper, was suddenly shocked, turned his head to look at Lu Zhou and said excitedly.

"Professor, tell me, what subject?"

He has been studying for a doctorate here in Lu Zhou for almost three years, and although he has made a lot of achievements, they are all dispensable jobs. In the final analysis, firstly, his level is average, and secondly, Lu Zhou is too busy to take him with him, and the papers he sends are basically for himself to choose topics.

Now that Lu Zhou suddenly said that he was going to give him a task, of course he was very excited.

“…… Well, not a subject. ”

Looking at his overly excited appearance, Lu Zhou probably guessed what he was thinking.

But unfortunately, although embarrassed to shatter his illusions, now is not the time.

Clearing his throat, Lu Zhou continued, "The day after tomorrow, there will be a discussion class in Room 101 of Teaching Building A, you will go to take a discussion class, the students are undergraduates, pay attention when choosing the topic, don't choose them to make them too uninvolved." I need you to prepare a discussion outline and bring it to me by tomorrow evening......"

As soon as he heard that it was a discussion class and that it was an undergraduate, He Changwen suddenly made a sad face.

"Professor, can't you give me some challenging tasks?"

Lu Zhou coughed and said seriously: "Do it well, this is your exercise...... If you do it well, there will soon be challenging tasks waiting for you. ”

"Yes......"

Putting aside the minutes of the meeting of the teaching and research group of the Light of Youth Class, Lu Zhou was about to start dealing with the work at hand, and a line of pop-up windows popped up in the lower right corner of the computer desktop in front of him.

Xiao Ai: [Master, you have a new email ヾ (● ゚▽ ゚●)]

Xiao Ai: [link]

Putting down the ballpoint pen in his hand, Lu Zhou held the mouse and clicked on the link that Xiao Ai popped up.

Upon entering the mailbox, he quickly saw an unread email, which was lying in the mailbox.

When he saw the IMU icon stuffed in the email, a surprised expression suddenly appeared on Lu Zhou's face.

International Union of Mathematicians?

Looking downward, Lu Zhou quickly followed the text part.

【…… Dear Professor Lu Zhou, I am sorry to disturb you in your busy schedule. According to the vote of all delegates at the last International Congress of Mathematicians, the next International Congress of Mathematicians will be held in St. Petersburg, Russia in 2022. On behalf of IMU, I would like to extend an invitation to you to give a 60-minute presentation at the International Congress of Mathematicians in St. Petersburg ......]

If you are interested, we will send you a formal written invitation. If you are too busy with research to attend, we hope you will get back to us as soon as possible......

[Helden Secretary-General of the International Union of Mathematicians]

After reading the email carefully to the end, Lu Zhou thought for a moment, then tapped his fingers on the keyboard, edited an email, and replied.

[Dear Professor Helden, it is an honor to receive your invitation.] 】

[If nothing else, I'll be heading to St. Petersburg for the next International Congress of Mathematicians, but I can't guarantee that I'll be there.] But if all goes well and I'm able to show up, I'll upload the content of the 60-minute presentation before the deadline. 】

Knocked down his name at the checkout office, and Lu Zhou replied to the email according to the address of the incoming letter.

When he was done, he leaned back in his office chair and looked out the window.

It's really fast......

It's been four years in the blink of an eye.

Looking at the scenery outside the window, Lu Zhou couldn't help but recall his life four years ago.

At that time, he was still a professor at Princeton, delving into the secrets of the NS equation. At that time, I probably lived a fulfilling life in another sense that was completely different from now.

Thinking of this, he actually began to miss it a little.

I don't know how his friends in Princeton are doing now......
