Chapter 140 World Congress of Chinese Mathematicians

It is said that if you don't return to your hometown when you are rich, it is like walking in the night in brocade clothes.

Xu Chuan has no intention of showing off, but he wants his family to live better than before.

Whether from the economic aspect or the spiritual aspect.

Although money cannot solve all problems 100%, it can solve more than 90% of the problems.

Prices are rising rapidly these days. More than one million yuan can indeed build a villa in the countryside, but if it is built and well done, there will be basically no money left.

Xu Chuan still wants to leave some money for his family. Anyway, these bonuses are of no use to him for the time being. It is better to leave them to his family, so that he will not have money and his family will still live a poor life as before.

Money, if you earn it, you must spend it. Money that is not used is just a number.

It's just that it's difficult to get his parents to accept this money. After all, he has already given his family a sum of money before, and his parents will definitely not accept it if he gives it again.

Fortunately, Xu Chuan is very familiar with his father. Sure enough, after he proposed to send money to his family under these two names, he hesitated for a while and finally nodded to agree.

Let's not talk about repairing the house, but Xu Jianguo would definitely approve of giving back to the village and helping the village repair the pond dam.

Xujia Village is a small village with one surname and one village. The village is not big, with only fifty or sixty households.

In the past few years, the Xu family received a lot of help from the village. Otherwise, with Xu's father's ability to farm and occasionally do some carpentry, he could not earn much money a year, and could not support the two children's schooling at all, especially since the two children were quite outstanding and all entered the provincial capital, so the expenses were even greater.

Before Xu Chuan graduated from high school, the family could almost count the 365 days of meat they ate in a year, and only when Xu Chuan or Xu Xiao returned home would the family eat meat.

If it weren't for the help of the village and the villagers, the Xu family would definitely be in debt now.

So Xu Jianguo still supported Xu Chuan's idea of ​​giving back to the village, but it didn't cost half a million to repair the pond dam.

There are several ponds in the village. How to repair them, how to build the dam, how many excavators and funds are needed, he can figure out these things after a little thought.

"By the way, Dad, Mom, there is one more thing."

Seeing his father agreed, Xu Chuan continued: "I have graduated from college. Next, I will study for a doctorate and study abroad. I will go to Princeton in the United States. It will take two to three years at the shortest, and three to five years at the longest."

You must tell your family about studying abroad to avoid worrying your parents.

Confucius said: "When your parents are alive, don't travel far."

But many people have misunderstood this sentence that is widely circulated in the market, thinking that children should not travel far while their parents are alive, so as not to be unfilial.

But there is actually another sentence behind it: "When your parents are alive, don't travel far, and when you travel, you must have a plan."

It means that when your parents are in good health, you should let your parents know that your destination is safe.

So Xu Chuan must explain it clearly to his family to avoid worrying them.

"Study abroad?"

Xu Jianguo was stunned for a moment. The previous second he was still thinking about how much money he should spend to repair the village pond, trying to save money while doing things well. The next second he was shocked by Xu Chuan's words.

"Then you can't go home in the past few years?" Xu's mother asked tremblingly.

Xu Chuan shook his head and said, "That's not the case. It's just that in the past few years of studying abroad, I may only be able to come back once a year during the Chinese New Year. After all, I still have a lot to learn, and I can't come back as soon as I say I will like in China."

Hearing this, Xu's father and mother were relieved at the same time. They thought Xu Chuan would not come back in the past few years, after all, going abroad is too far away from rural people like them.

"Chuan'er, we will definitely support you to study abroad, but after you go out, you must take good care of yourself and call home more often."

Xu's mother nagging, Xu Chuan listened carefully, nodded from time to time, and Xu's father ate silently, occasionally looking up at his son.

Although Xu Chuan is an adult and has the ability to take care of himself, it is impossible for parents not to worry about their children traveling far away.

After staying at home for a few days, he went to Xingcheng No. 1 Middle School to see Xu Xiao, the girl, and left some living expenses and pocket money for her. Xu Chuan finally embarked on a new journey alone.

Back at Nanjing University, Xu Chuan sorted out the things in the dormitory to prepare for his next trip abroad.

He didn't have many daily necessities when he lived alone, but more of various books, manuscripts, printed materials and papers, etc.

There were a lot of these things, filling up bookshelves, drawers and other places. If you sell waste paper at 50 cents per pound, you can sell hundreds of yuan.

Of course, Xu Chuan couldn't buy these things for waste paper. For him, these things carry memories.

And it's no exaggeration to say that these things will be cultural relics in the future.

Think about Einstein's study notes. If they are auctioned, millions of dollars can be easily bought.

Of course, this is also related to Einstein's death.

Just like a painter, no matter how famous his paintings are during his lifetime, they can't match the soaring prices of his paintings after his death.

But now Xu Chuan is a bit overwhelmed, there are too many books and materials. He has read more math books in the past year than other college students have read in four years of college.

On the bed in another room of the dormitory, there are all kinds of books standing upright.

"Forget it, sort out the key materials, take some of the unfinished ones to Princeton, keep some of the commemorative ones, and give the rest to students in the Department of Mathematics."

Xu Chuan muttered and began to sort out the books, materials and manuscripts in his dormitory.

There are many books, papers and manuscripts in his dormitory. It is not realistic to take them all away, but it is a bit too wasteful to leave them all in this dormitory.

There are many notes and insights from reading these books and printed papers. These things are not very useful to him because the knowledge is in his mind.

But for other students in the Department of Mathematics, these things should be regarded as treasures. They can read through his learning journey and some methods and ideas for solving problems.

More or less, they can bring some inspiration to others.

Especially those printed papers, which are more valuable. Not everyone has scientific research funds or money to buy these things.

Of course, the books and materials that can be given out are limited to mathematics. Forget physics. In one year of college, he didn't read much physics books, and he didn't even write his name on the textbooks he was given.

After two or three hours of hard work, Xu Chuan finally finished cleaning the dormitory.

The sorted things were divided into three piles.

The smallest pile of materials was some manuscripts, which he planned to keep, such as the weak Weyl-Berry conjecture, the proof process and manuscripts of the Weyl-Berry conjecture, and the distortion and application of the Xu-Weyl-Berry theorem.

These things have a very high nostalgic and collection value for him, so Xu Chuan kept them.

As for the middle part, there are several mathematics books and some paper documents, which are the manuscripts and corresponding books of his unfinished work.

Such as the literature and paper materials related to the "proton radius mystery", as well as some data he manually analyzed and calculated.

He has to take these things to Princeton to facilitate him to continue to complete the rest of the work.

As for the remaining pile, it is all various books, notebooks and some manuscripts with complete calculation processes.

These things are still useful for his classmates in the Department of Mathematics of the same year.

After sorting out the books and materials in the dormitory, Xu Chuan did not make a big fuss. He just quietly found the students who needed these books and gave them the prepared books.

There are more than 80 people in the Department of Mathematics. Even if he has read a lot of books in the past year, it is impossible to give each student one book.

Moreover, these books also have his hard work and study notes. He naturally hopes that the people who receive them will treat them well.

Although Nanjing University is a top 985 university, not everyone still loves to study after entering. Most of them work hard, but there are also many who just get by.

Everyone has their own choices. Xu Chuan cannot evaluate them, but he can make his own choices and give a little help to those hard-working students.

After dealing with the things in his hands, the Morning Star Mathematics Award will also be awarded.

After buying a high-speed rail ticket, Xu Chuan and Rong Zhizhuan, the dean of the School of Mathematics, went to the capital together. This year's Morning Star Mathematics will be awarded at the 7th World Chinese Mathematicians Conference, which will be held at Shuimu University.

At this World Chinese Mathematics Conference, the Chen Xingshen Award and the ICCM International Cooperation Award were also awarded together with the Morning Star Mathematics Award.

The former was established by the International Mathematical Union in memory of the late Chinese mathematician Shiing-Shen Chern, and is awarded to scientists who have made outstanding achievements in the field of international mathematics.

This is also the first mathematics award named after a Chinese mathematician by the International Mathematical Union. It is a lifetime achievement award similar to the Wolf Prize.

Although there is no age limit for the Chern Prize, and Xu Chuan is also qualified enough to win this award, he can forget about it at this Chinese Mathematician Conference.

This kind of lifetime achievement award is basically awarded to mathematicians over 40 years old or even older.

After all, if you give a lifetime achievement award to a mathematician under 40, it means a little bit of cursing that he will have a short life or will not be able to make breakthroughs in the future, which is not good.

If the Chern Mathematics Award was awarded at this conference, Xu Chuan might have won it, but unfortunately the Chern Mathematics Award will not be held until next year.

As for the ICCM International Cooperation Award, it is similar to the Chern Prize. It is mainly awarded to leading mathematicians who have made outstanding achievements and are highly respected in the field of mathematical sciences, in recognition of their outstanding lifetime contributions to the rise of China's mathematical career.

In this World Chinese Mathematicians Conference, only Xu Chuan and Rong Zhizhuan were invited to attend the conference.

Xu Chuan was the only one invited to give a report at the conference. Rong Zhizhuan was invited because of Nanjing University. After all, it is a top university in China and must be invited.

As for other mathematics professors in Nanjing University, none of them received an invitation.

Of course, you can still attend without an invitation, but you have to pay for food and accommodation, and you can't attend the party on the last day.

Xu Chuan followed Rong Zhizhuan and they came to Wenjin International Hotel next to Shuimu University.

This is one of the best hotels near Shuimu University. Usually, an ordinary room costs two to three thousand yuan a night.

However, as a guest invited to attend the mathematics conference, Xu Chuan naturally doesn't need to worry about food and accommodation, as the Chinese Mathematics Conference has already arranged it.

After handing the invitation letter to the front desk staff, Xu Chuan signed his name on the report form and took the conference card in the surprised eyes of the young and beautiful front desk lady.

"President Rong, which room are you staying in?"

Dragging the suitcase, Xu Chuan walked towards the elevator with Rong Zhizhuan, pressed his own floor and asked.

"Let me see." Rong Zhizhuan flipped the room card in his hand and said, "1719."

Xu Chuan nodded and pressed the seventeenth floor.

The elevator door slowly closed, but it was blocked by someone's hand halfway through.

"Sorry, please wait."

A voice came into the elevator, and Xu Chuan looked up and saw a young man who was older than him blocking the door with his hand, followed by a familiar figure.

And this familiar figure suddenly brightened up when he saw Xu Chuan, and took the initiative to smile and greet him.

"Long time no see, Xu Chuan."

Xu Chuan quickly replied: "Academician Zhang, hello."

This familiar figure is Academician Zhang Weiping of Sun Moon University. He had wanted to recruit Xu Chuan as a disciple, but unfortunately Xu Chuan eventually went to Nanjing University.

Seeing Xu Chuan again, Zhang Weiping had mixed feelings and regretted not insisting a little bit.

He knew Xu Chuan had a good talent for mathematics, but he didn't expect it to be so good that he solved a world-class mathematical conjecture in one year of college.

If only he had insisted a little bit more.

After a brief moment of distraction, Zhang Weiping walked back into the elevator, stood beside Xu Chuan, and smiled and greeted Rong Zhizhuan.

"Dean Rong is here too. You have a good student from Nanjing University. If I had persisted a little longer during the IMO training, Xu Chuan might have been my student."

Rong Zhizhuan smiled and nodded, "Xu Chuan is indeed very good, but there are also many mathematical geniuses in Sun Moon University. The one behind you is Hu Xingjian, who won the gold medal in the Qiu Chengtong College Mathematics Competition two years ago. He is also very good."

In the past two years, he served as a judge in the Qiu Chengtong College Mathematics Competition. Naturally, he knew this gold medalist. Although his talent was not as good as Xu Chuan, he was also outstanding.

Zhang Weiping shook his head and didn't care about the feelings of the young people around him. He said directly: "Who can compare with Xu Chuan in the younger generation?"

"Xingjian, let me introduce myself," "This is Dean Rong Zhizhuan of the School of Mathematics of Nanjing University, and the one next to him is the genius I mentioned to you before, Xu Chuan, who proved the Weyl-Berry conjecture. "

"Hello, Dean Rong, hello, God Chuan. "

Following Zhang Weiping, Hu Xingjian came out and greeted him.

On the side, Zhang Weiping continued: "At this mathematics conference, you should communicate and learn with Xu Chuan. He is a top mathematician in the field of spectral fractals that you are studying."

As he said, he looked at Xu Chuan again and smiled: "Xu Chuan, this is my student, Hu Xingjian, who is a second-year graduate student this year. His field of study is spectral theory and Hilbert space. I know you will come to this conference, so I specially brought him here to learn from you. Don't hide anything, give him some advice."

Xu Chuan quickly said: "I don't dare to give you advice, just learn from each other."
