He proved Calabi's conjecture and positive mass conjecture in Einstein's equation, and initiated the mathematical branch of geometric analysis. 1982 won the Fields Prize, known as the Nobel Prize in Mathematics, and became the first mathematician in China to win the highest international prize in mathematics. At the same time, he is also the first person to be a professor in both the Department of Mathematics and the Department of Physics since the establishment of Harvard University.
In the educational public welfare undertakings:
Although Qiu Chengtong lived abroad in his early years, his support for education in China never stopped. Since 1984, he has enrolled more than a dozen doctoral students in China and trained world-class differential geometricians such as Tian Gang for China.
In addition, he also established the Institute of Mathematics of the Chinese University of Hong Kong, the Morningside Mathematics Center of Beijing, the Mathematics Science Center of Zhejiang University, the Tsinghua University Mathematics Research Center and other institutions through fund-raising, which provided strong institutional support for training professional mathematics talents in China.
Professor Qiu Chengtong has said many times that "a country cannot have good science and technology without a strong mathematical foundation" and "what we should do is to train top mathematicians in China". It can be seen that he has a sincere heart to devote himself to the cause of mathematics construction in China. I believe that in the future, under the leadership of Professor Qiu Chengtong, China's mathematical research will advance by leaps and bounds, and other scientific fields based on mathematics will also make greater achievements. Let's wait and see!
