Gu Chaohao (1926.5.15-2012.6.24), Han nationality, Wenzhou, Zhejiang, mathematician, party member, the producer of China, a member of the NLD, won the highest national science and technology award in 2009. 1 1948, Gu Chaohao graduated from the Mathematics Department of Zhejiang University; 1in June, 1959, he received his doctorate in physics-mathematics science from Moscow University; 1980 was elected as an academician of China Academy of Sciences; 1982 1 month, served as vice president of Fudan university; 1February, 988, President of the Chinese University of Science and Technology; 1August 1999 President of Wenzhou University. Gu Chaohao is mainly engaged in the research and teaching of partial differential equations, differential geometry, mathematical physics and so on. Systematic and important research results have been obtained in general space differential geometry, homogeneous Riemannian space, infinite dimensional transformation quasigroups, hyperbolic and mixed partial differential equations, gauge field theory, harmonic mapping and soliton theory. Especially, the system theory of high-dimensional and high-order mixed equations, the mathematical problems in supersonic flow, the mathematical structure of gauge field, fluctuations and so on are put forward for the first time.
