Cheng dongyou
Qiu Chengtong, 1949 was born in Shantou, Guangdong Province in April. His ancestral home is Jiaoling, Meizhou. He is a Chinese-American mathematician, the first Chinese to win the Fields Medal, a member of the National Academy of Sciences, an American Academy of Arts and Sciences, a foreign member of the China Academy of Sciences, an academician of the Academia Sinica, and the director of the Qiu Chengtong Mathematical Science Center.
Qiu Chengtong has been engaged in the research of mathematics and physics for a long time. He devoted himself to solving mathematical problems caused by string theory of general relativity. He systematically developed the method of partial differential equations in differential geometry. With these methods, he solved Calabi's conjecture and won the Fields Prize of 1982.
He also solved the existence of Hermite (or "Hermite") Young-Mills connection (in cooperation with Uhlenbeck) and solved the positive mass conjecture through the minimum surface theory (in cooperation with Schon). He introduced geometric methods to solve important problems in general relativity, such as Schon-Hill's black hole existence theorem and the internal definition of quasi-local mass in general relativity.
Knowledge expansion:
Qiu Chengtong's research on the existence of Keller-Einstein metric led to the solution of Calabi's conjecture, and introduced the concept of Calabi-Churchill manifold, which is the cornerstone of string theory and complex geometry. Strominger-Hill-Zaslo structure has great influence on the study of mirror symmetry.
Qiu Chengtong's (and Li Weiguang's) research on thermonuclear estimation and differential Hanak inequality changed the analysis method of geometric equations on manifolds. It also influenced the development of optimal transportation and Hamilton's research on Ritchie flow.
Qiu Chengtong also made great contributions to various branches of engineering, including cybernetics, graph theory (applied to social sciences), data analysis, artificial intelligence and three-dimensional image processing.
Qiu Chengtong organized conferences at all levels, raised a large amount of funds to carry out various talent training programs, and set up Qiu Chengtong Middle School Science Award, Qiu Chengtong University Student Mathematics Competition, New World Mathematics Award and other awards to encourage students to carry out innovative learning and research, so as to cultivate outstanding mathematical science and technology talents for China.
