Why did Xu Chenyang leave Peking University in the United States for his math learning journey?

Because he believes that the teaching resources in the United States are more abundant, which will help him improve his mathematics level and seek higher development.

This is because if you want to learn mathematics well, you can't do it only at Peking University, so he went to the United States to study mathematics at that time, which made his mathematical knowledge more profound.

Xu Chenyang thought that the support for young talents in China was not enough, and the application for scientific research funds was too particular about seniority, so he went to the Department of Mathematics of the Massachusetts Institute of Technology.

Because he feels that it is the United States that has cultivated him, and he wants to spend his life to repay the United States, which can only be said that people are different.

This is because after he returned to China to teach, he found that his future career planning was not particularly helpful, and his personal salary was not very high during his teaching in China, so he chose to return to the United States to work in a high-paying job to improve his life.

Because he is a very patriotic person, he wants to contribute his knowledge to the motherland, and he wants to build the motherland stronger, so he will return to the motherland.

Probably after 6 years in China, he felt very disappointed, so he returned to the United States.

Mathematics genius Chenyang Xu's current situation: teaches in the Department of Mathematics at the Massachusetts Institute of Technology.

1. Xu Chenyang's experience.

1) In 1981, Xu Chenyang was born in Chongqing; In 1999, he was selected into the National Mathematics Training Team; In the same year, he entered the School of Mathematical Sciences of Peking University. In 2002, he received a bachelor's degree, and then continued to study at Peking University as a graduate student under the supervision of Academician Tian Gang. In 2004, he received a master's degree from Peking University. In 2008, he received his Ph.D. in mathematics from Princeton University, then went to the Massachusetts Institute of Technology for postdoctoral research before working at the University of Utah for one year.

2) In 2012, he returned to Peking University and joined the Beijing National Calendar Liangji Mathematics Research Center. In 2013, he became a professor at the Beijing International Mathematical Research Center. In 2014, he was awarded the National Science Grant for Distinguished Young Scholars and was named a distinguished professor of Peking University. In 2016, he was selected as a young and middle-aged leading talent in scientific and technological innovation; In 2017, he was selected by the Institut Poincaré and was the only young Chinese mathematician selected (as of 2017); In 2018, he joined the Department of Mathematics at the Massachusetts Institute of Technology (MIT) as a full-time faculty member.

Second, Xu Chenyang's main achievements.

Xu Chenyang's main research achievements include the bounded theory of general logarithmic canonical couples, the proof of the ascending chain conjecture of logarithmic canonical thresholds, which greatly promoted the program of three-dimensional minimatrical models of positive features, made a breakthrough in the subtle mode implicit program of logarithmic canonical singularities, solved the problem of non-problem of asymptotic weekly stable compaction of canonical polarization clusters in the preface of Geometric Invariant Theory, and systematically studied and developed the theory of dual complexes.

As a mathematician, he finally chose to study abroad, because he felt that some domestic scientific and technological academics were not particularly perfect, and the industry was not particularly friendly to newcomers, and some overseas professional knowledge should be more comprehensive.

The reason is that the family conditions are good, and the parents sponsor him to go abroad for further study; Xu Chenyang is very yearning for foreign scientific knowledge.

He is dissatisfied with some aspects of the country's education system, such as China's lack of support for newcomers and the preference for those with old qualifications.

As far as I know, the reason why mathematician Xu Chenyang left Beidao to study abroad is because he wants to improve his mathematical ability more quickly and learn more skills to benefit his country.

The reason for studying abroad is nothing more than to help yourself in your studies, or to help you in the future. But in fact, if you want to make more progress in mathematics, it is normal to study abroad.

I think he is a person with more seniority and has experienced a lot of things and has a story, so I admire him very much.

Xu Chenyang, an associate professor of mathematics at Peking University, is a very good person, his logical thinking is very strong, his mathematical ability is also outstanding, and he is a relatively rational thinking person.

Xu Chenyang was a full professor before leaving Peking University, went to the United States as a full professor at MIT, and transferred to Princeton University as a full professor in September 2020.

His main research achievements include the boundedness theory of general logarithmic canonical couples, the conjecture of the rising chain of logarithmic canonical thresholds, which greatly promoted the program of positive characteristic three-dimensional minimal models, made a breakthrough in the program of minimalist models of logarithmic canonical singularities, proved the equivalence of Tian Gang and Donaldson's definition of k-stability, solved the problem of non-regularization of asymptotic weekly stability of canonical polarization clusters in the preface of Geometric Invariant Theory, and systematically studied and developed the theory of dual complexes. At present, he has published a number of articles in top international mathematics journals.

Xu is a professor, not an associate professor.
