Chen Xiuxiong, senior apprentice, Grade 02 alumnus of the Junior Class of the University of Science and Technology of China Sun Song , Guan Xuan joined the Institute of Advanced Mathematics of Zhejiang University!
According to the official news of Zhejiang University, Sun Song, a professor in the Department of Mathematics at the University of California, Berkeley, has now Joined Zhejiang University full time as Professor Du Jianying 。
Sun Song's long-term deep cultivation Differential geometry, complex geometry and geometric analysis Domain.
At the age of 27, Sun Song, together with his tutor, solved the problem that has puzzled the mathematical world for nearly 40 years, and later won one of the highest honors in the international geometry field—— Wimbledon Geometry Award 。
At the same time, Simon Donaldson, the winner of the Fields Prize, won the prize.
He has also won the Sloan Research Award, the Scientific Breakthrough Award – New Vision Award in Mathematics, and so on, which is known as the "vane of Nobel Prize". He was invited to give a 45 minute speech at the International Conference of Mathematicians.
He was born in 1987 after joining the Institute of Advanced Mathematics of Zhejiang University The fifth permanent member , is also the youngest one.
The other four members are also famous top mathematicians, namely: founding president, academicians of the Chinese Academy of Sciences Li Jianshu , Academician of Chinese Academy of Sciences Ruan Yongbin , Academician of Chinese Academy of Sciences Sun Binyong , the "golden generation" of mathematics at Peking University, former professor of mathematics at Yale University Liu Yifeng 。
Put an end to the Kalabi conjecture
One of Sun Song's main research achievements is that in 2014, together with his tutor Chen Xiuxiong and the 1986 Fields Prize winner Simon Donaldson, he proved that first Chen (body saving) Kalabi conjecture with class as timing 。
At that time, Sun Song was only 27 years old, nearly 40 years had passed since Qiu Chengtong had proved the "first half" of the Kalabi conjecture.

In 1954, the International Mathematical Congress was held in Amsterdam. In the invitation report of the conference, Karabi wrote down his famous conjecture on one page:
Let M be a compact Kahler manifold, then for any (1,1) form R in its first class, there is a unique Culler Einstein metric Its Ricci form is just R.
It is described in physical language, that is, whether it is possible to exist in a closed space Gravitational field without matter distribution ？
In 1976, Qiu Chengtong successfully proved the Kalabi conjecture when the first class was negative or zero by using the concept of curvature in Culler geometry.
It is worth mentioning that Qiu Chengtong was also 27 years old.
For the case that the first Chen class is positive, Qiu Chengtong proposed a proof idea, that is, the existence of the Carler Einstein metric in space is transformed into the stability of algebraic geometry, which is called "Qiu Chengtong's conjecture" in the academic world.
However, Qiu Chengtong himself failed to give a specific proof process.
Finally, the three people gave the final proof of this conjecture by constantly constructing approximations, and three series of papers were published in the Journal of the American Mathematical Society, the top journal of international mathematics.
The reviewer commented that:
The proof is a breakthrough. It not only solves a basic problem, but also develops many new and powerful tools to reveal the profound relationship between Carlyle geometry, algebraic geometry and partial differential equations.
So far, with the efforts of three generations of masters and apprentices (Chen Xiuxiong is Professor Karabi's "closed disciple") and mathematicians of all ages for 60 years, the Karabi conjecture has finally come to a perfect end.
In 2014, Sun Song won the Sloan Research Award, which is known as the "vane of the Nobel Prize", for his "work in Culler's geometry".
The Sloan Research Award aims to support and reward "outstanding scholars at the early stage of their careers". So far, more than 50 Nobel Prize winners have been born among the winners of the Sloan Research Award.
In 2018, because of the proof of Qiu Chengtong's conjecture, Sun Song, 32, together with his mentor Chen Xiuxiong and Simon Donaldson, won the Wimbledon Prize.
It is worth noting that Simon was the winner of the Fields Prize in 1986, when he was nearly sixty years old.
This award is awarded by the American Mathematical Society, and is aimed at scholars who have made significant achievements in the field of geometry or topology. Qiu Chengtong also won this award in 1981.
In the same year, Sun Song was invited to give a 45 minute report at the International Conference of Mathematicians.
Then, the Scientific Breakthrough Award Review Committee awarded Sun Song the 2021 New Vision Award for Mathematics, "to commend his series of pioneering contributions in the field of complex geometry."
The Scientific Breakthrough Award is known as the "Oscar of the scientific community", which aims to commend the world's top scientists.
Among them, no more than 3 people will be awarded the Math New Vision Award every year, which is specially aimed at young researchers to recognize their outstanding achievements in their respective fields.
The youngest permanent member of the Supreme People's Court of Zhejiang University
Looking back on Sun Song's mathematical career, he often said that there was no shortcut, and interest was the prerequisite for seeking.
According to his statement on the official micro blog of Zhejiang University:
I think we need to have a genuine desire to understand mathematics. Research needs to be focused, and more importantly, we need to stick to our own path and study issues that we find interesting.
Driven by his interest, Sun Song's mathematical career can be described as "high opening and high going".

In 2000, Sun Song was admitted to Huaining Middle School in Anhui Province with the first result in the middle school entrance examination.
Senior two, participated in the national chemistry contest for senior high school students and won the second prize; In the same year, he participated in the college entrance examination and was admitted to the Junior Class of the University of Science and Technology of China. Sun Song thus became the first person in Huaining County admitted to the junior class of HKUST.
In 2006, Sun Song received a full scholarship to study in the Department of Mathematics of the University of Wisconsin in the United States, and received a doctor's degree four years later.
It was during my doctoral study that I learned from well-known geometry experts Chen Xiuxiong 。

Chen Xiuxiong is a tenured professor at the University of Wisconsin and a professor at the State University of New York at Stony Brook.
In addition, he is also the founding director of the Center for Geometric and Physical Research of the University of Science and Technology of China, "Wu Wenjun, chair professor", and the founding director and distinguished professor of the Institute of Mathematical Science of Shanghai University of Science and Technology.
In addition to the Wimbledon Award, he is also the winner of the 2019 Simmons Scholars Award and the third Chinese mathematician to win the Simmons Scholars Award after Tao Zhexuan and Yao Hongze.
As it happens, Professor Chen Xiuxiong is a 1982 alumnus of the University of Science and Technology of China. The time between the master and the apprentice is exactly 20 years apart.
After graduation, Sun Song served as an assistant professor of the State University of New York at Stony Brook; In 2018, he served as associate professor and full professor of the Department of Mathematics at the University of California, Berkeley.
This time, Sun Song will become the fifth permanent member of the High Court of Zhejiang University, and he was born in 1987, which is also the youngest among them.
According to the official WeChat official account of Zhejiang University, Sun Song's specific position is Professor Du Jianying , he said:
After joining Zhejiang University, I will do my own academic research, guide students who are interested in mathematics, and try my best to pass on my major to the younger generation.
The High School of Mathematics of Zhejiang University was founded in 2017, and Li Jianshu, an academician of the Chinese Academy of Sciences, is the founding president of the Academy.
In 2019, Ruan Yongbin, a chair professor at the University of Michigan, joined us. Professor Ruan Yongbin has been committed to the research of Xin's geometry, mathematical physics and other fields for a long time, and was elected as an academician of the Chinese Academy of Sciences in 2021.
One year later, Sun Binyong, the youngest academician of the Chinese Academy of Sciences at that time, also joined the High School and continued to work in fields such as Li Qun's Theory of Expression.
At the same time, a year later, Liu Yifeng, the "golden generation" of mathematics at Peking University, joined us. Before that, he was a full professor at Yale University. After joining the High School of Mathematics, he published three papers in the four top journals of mathematics.
