After chatting with Mu Liangcai for a while, Xu Chuan said goodbye to the two and left alone. Diaphragm

In the villa apartment, Pan Deming sat opposite Mu Liangcai, with a smile on his face, took a sip of tea and said, "It's good to return to China, Professor Xu is a real genius." ”

On the other side, Mu Liangcai also smiled and said: "Yes, Professor Xu is a real top scholar, such a scholar, we are more at ease when we return to China as soon as possible, stay over there, there are too many accidents." ”

"If it weren't for other arrangements, we would have taken him back to China a long time ago."

Pan Deming smiled and said, "I don't know how far he can go in the future, but at present, he is still dedicated to learning." ”

After a pause, Pan Lao sighed again, and continued: "The domestic academic environment needs to be rectified, it is too bad to retain talents." ”

"We have a very unhealthy traditional thinking that intellectuals should be poor, and scientific research funds should be mainly used to buy instruments and equipment, resulting in a greater restriction on labor fees for scientific researchers."

"This kind of thinking is extremely harmful to the development of science, and compared with advocating feelings, it is really feasible to effectively improve the treatment of scientific researchers, especially graduate students." Diaphragm

On the other side, Mu Liangcai smiled and didn't speak.

Some things, not that they don't know, but it's too hard to change.

In many cases, it is not that the state does not do it, but that it cannot do it, or that it has to pay a great price if it is done, and it is not worth it in comparison.

Changes in the academic system, changes in scientific research, these need to be supported by money.

State, no money. That's the biggest problem.

Don't look at China's GDP ranks second in the world, second only to the United States, but that is based on a large volume, on average, to each person, directly dropped fifty places.

The volume is large, and anything that changes is a stormy wave. Diaphragm

I want to change it, but it's hard.

The boat is small and easy to turn around, but when the ship is big, it needs a long path.

But as long as you go in the right direction, you can always do it.

......

Xu Chuan didn't think about it so much, he didn't really care much about the academic environment in China now, or he didn't think about it so much.

All he wants now is a clean academic environment in China.

This is difficult for others to do, but it is not so difficult for him, the state invites, he makes a request, and it is enough to say something above. Diaphragm

Thinking about it, Xu Chuan stepped into the venue of the exchange conference, ready to exchange ideas with other mathematicians.

This International Congress of Mathematics is probably the last good opportunity.

If he misses it, he will have to wait for another four years, and second, whether he will be able to go abroad for exchanges after four years is a question, after all, he is still only a pure theoretical research scholar, and all the results are basically public, and every country can learn from them.

After returning to China, he switched to application and began to study superconducting materials at room temperature, nanomaterials, and other things, which was a big trouble.

When the time comes, if he wants to go out, someone will be arranged to dissuade him.

However, if it is difficult to go abroad, maybe there will be an opportunity to promote the International Mathematical Conference to be held in China, so that he does not need to go out.

Moreover, with his current ability, coupled with the economic take-off of China, the national strength is much stronger, and there may not be no hope of accomplishing this. Diaphragm

At least in China, it is impossible for a thief to steal a Fields Medal medalist at a mathematics conference.

At this International Mathematical Union, he may be able to use this point to promote it.

Although it is a little late to make a move now, it must still be done, as a large country with the second largest economy in the world, it has held an International Mathematical Conference, which is also too shabby.

However, if you do it, it is also a troublesome matter, and you have to contact some mathematicians at home and abroad to jointly promote it.

It is difficult for him alone, even if he is a Filipino Award winner, to promote this.

"Forget it, let's talk about it first, anyway, it's not in a hurry, it won't be a meeting until the next day after the end of the meeting, and there is still time to do it."

Shaking his head, Xu Chuan stepped into the exchange hall and went to find other mathematicians to communicate. Diaphragm

......

An afternoon passed quickly.

On August 2, the second day of the International Congress of Mathematicians, the Mathematics Exchange Conference officially began.

Every four years, the International Mathematical Union invites a group of top mathematicians to give presentations at the International Congress of Mathematicians.

This is not only their duty, but also the honor of mathematicians who come to the stage to make presentations.

The mathematicians who can be invited to give a 45-minute or one-hour presentation at the conference are the top talents in various countries.

Just like Huaguo, if you have the ability to give a 45-minute presentation at an international mathematical conference, you are eligible to apply for Changjiang Scholars; If it is a one-hour presentation, they are even eligible to apply for a national academician. Diaphragm

Of course, at the International Congress of Mathematicians, in addition to the one-hour and 45-minute presentations that start at a fixed time, there are also 10-minute presentations for general scholars.

Any scholar who attends this mathematics conference can apply to the International Mathematical Union for a ten-minute presentation in their field of interest to demonstrate their abilities.

If you are lucky and fall into the eyes of a top bull, you may have a greater chance.

For this opportunity to intuitively understand the latest research trends in the mathematical community and supplement their knowledge in the field of interest, the mathematicians who came to the conference will not easily let go.

Of course, due to the development of mathematics today, there are quite a lot of presentations at each International Mathematical Congress.

There are hundreds of presentations just by invitation, not to mention the 10th of the presentations that apply independently, and the number is even more.

In order to enable mathematicians to find the presentations they are interested in, the organizers of the International Mathematical Union have organized the reports of these applications into categories. Diaphragm

】

This year's International Congress of Mathematics has divided into more than 20 categories.

Xu Chuan didn't know exactly how many classifications there were, and he didn't look at those tables carefully.

In fact, at his point, most of the presentations were of little value, and in general, only those held by mathematicians of the same class had that value.

After all, the conference is not a private exchange, it is open to mathematicians from all over the world, and many imperfect things cannot be brought out at this kind of meeting.

However, the presentations at the International Congress of Mathematicians are of high quality, and many times, some top mathematicians will also look for some other big names that they are interested in to learn about mathematics in other fields.

.....

In the venue, Xu Chuan came over with four students in formal clothes. Diaphragm

At the request of the International Mathematical Union, he had two presentations, one on the Hyun-Hodge theorem, scheduled for the afternoon of the third day.

The other was an extension of the application of the xu-weyl-berry theorem won by the astronomical and astrophysical communities, which was scheduled for 9 a.m. on the first day.

On the one hand, this arrangement is to attract astronomers and astrophysicists to the opening ceremony and expand the influence of mathematics.

On the other hand, it is convenient for those astronomers and astrophysicists who came to the conference to leave the venue early after listening to the presentation.

After all, the International Mathematical Congress will be held for nine full days.

At eight o'clock, the venue was already crowded, and the crowd was surging, and the huge venue was almost unable to sit down.

However, nearly half of the scholars who attended the seminar were not mathematicians. Diaphragm

At the International Congress of Mathematicians, a report meeting of mathematicians, more than half of the scholars who came to listen to the meeting were not mathematicians, which is also a rare thing, and this is the first time in history.

"Come on, Professor!"

Near the start of the briefing meeting, Amelia, who was sitting next to Xu Chuan, smiled and cheered him up.

Xu Chuan smiled and nodded, got up and walked onto the podium.

Although there was a theft of the Fields Medal medal at this international mathematical congress, the specifications were never lowered.

Taking the microphone from the host's hand, Xu Chuan handed over a USB flash drive to the staff and connected it to the virtual projection.

The USB flash drive is the content of this report, and the International Mathematical Union also has a backup. However, considering that sometimes the presenter will make some minor changes to the content of the report, all the ones used are generally the one provided by the presenter on site, so as to facilitate the adaptation of the speaker to make academic reports. Diaphragm

Of course, that kind of big change is definitely not allowed, for example, you submitted to the International Mathematical Union a report on the Hodge conjecture, but you changed it to the Riemann conjecture on the impromptu stage, which is not okay. By doing this, you are playing with others and wasting everyone's time.

Xu Chuan has no idea of changing the content of the submission, today's report will be requested by many top scholars in the astronomical and astrophysical circles to the Mathematical Union, and the things he submitted have been read by most of the people in the audience, and it is very troublesome to make changes.

With Xu Chuan coming to the stage, the originally noisy venue instantly quieted down, and more than 2,000 people in the venue all cast their eyes.

This year's International Congress of Mathematics had less than 4,000 participants, including nearly 1,000 non-mathematicians.

This report meeting gathered nearly half of the people of this international mathematical conference.

The other more than 20 reported venues were divided into half, and on average, there were more than 100 people in one venue, and the disparity in the number of people was so large that it was extremely rare.

Originally, many mathematicians were not very interested in expanding the application of the xu-weyl-berry theorem, but a large number of people from the astronomical and astrophysical circles came together to arouse their interest. Diaphragm

In addition, there was no report meeting of other top bulls arranged today, which caused Xu Chuan to attract nearly half of the people to come over.

Facing nearly 2,000 people in the audience, Xu Chuan smiled, briefly introduced himself and the content of this report, and then began to explain the extended application of the xu-weyl-berry theorem.

“...... In order to truly understand and exploit the xu-weyl-berry theorem, it is necessary to fully understand the weak weyl-berry conjecture and the weyl-berry proof process. ”

"This extension is not simply developed from the Xu-Weyl-Berry theorem, and some mathematical methods in the proof process of the weak Weyl-Berry conjecture are also the core ....."

“..... A fairly accurate calculation of the upper and lower bounds of the counting function n(λ) connected by the fractal drum is made, and then a 'small opening' is made between the non-connected branches of the region to connect the disconnected region....... In this way, the previously discussed example of disconnected regions becomes the case of regions, and in this way, it is possible to continuously connect the discontinuities of eigenvalues....."

"And the parameter of the boundary value ......"

In the venue, Nobel laureate Professor Sal Polmatt sat in the front row, looked at Xu Chuan on the stage with glasses, listened carefully for a while, and poked his friend Brian Schmidt with his hand. Diaphragm

"Our last application was really the right choice."

Brian Schmidt didn't turn his head back, but just nodded in response.

He was reluctant to turn his head and talk to Polmatt beside him, for fear of distracting himself and missing some details.

This time, the young man on the stage, even if it was just beginning, let him see something he had never seen before.

It's detailed, it's interesting, and it's practical. At least, yes for the field of astrophysics to calculate parametric information about distant celestial bodies.

In the past, few people in the astronomical and astrophysical circles could use the Xu-Weyl-Berry theorem to extend the application to complete the calculation of the parameters of distant celestial bodies.

But after this report meeting, there will definitely be some more people. At least, there is a high probability that he can figure it out, and Saar Polmatt next to him can figure it out. Diaphragm

Astronomers and astrophysicists had gains, as did the mathematicians in the room.

Although the extended application of the xu-weyl-berry theorem is a method for calculating distant celestial objects, it is not applicable to other mathematical calculations, but in the final analysis, it is mathematics.

is mathematics, then its foundation applies to mathematics.

Whether it is the exact calculation of the counting function n(λ) associated with fractal drums in the weak Weyl-Berry conjecture proof; Or the torsion method in the xu-weyl-berry theorem......

These are all quite subtle things, broken down, each one is wisdom, and when fused together, it is knowledge built with wisdom.

Knowledge, on the other hand, can be learned and absorbed, transformed into their own things, and then applied to other problems.

...... Diaphragm

On the podium, Xu Chuan followed the PPT text little by little to explain the extended application of the xu-weyl-berry theorem.

Unlike in the past, this time he spoke in great detail, and he broke down almost all the key details related to the calculation.

The joint request of several Nobel laureates and dozens of top scholars still needs to be seriously responded.

On the stage, Xu Chuan explained seriously.

In the audience, most of the scholars were listening attentively, even those students who had come to increase their knowledge with their mentors.

This is not so much a presentation as a class.

On the podium, a teacher was lecturing, and off the stage, 2,000 students were listening carefully to the lecture. Diaphragm

Preaching and receiving karma to solve doubts, and people are also going~
