As the saying goes: "It is difficult to produce bright, fragrant, cold-resistant and proud snowflakes in the greenhouse. Only after suffering and tempering can people hope to succeed." Comrade Hua is a famous mathematician in China, and his rough experience has benefited him a lot. 1924 Jintan middle school graduated from junior high school, but due to poor family circumstances, he had to drop out of school after finishing junior high school and became a shop assistant. /kloc-suffered from typhoid fever at the age of 0/8, resulting in disability of his right leg. 1930, taught in Tsinghua University. 1936 Visiting study at Cambridge University, UK. 1938 became a professor in The National SouthWest Associated University after returning to China. From 65438 to 0946, he went to the United States and served as a researcher at Princeton Institute of Mathematics, a professor at Princeton University and the University of Illinois, and returned to China from 65438 to 0950. He has served as Professor Tsinghua University, director and honorary director of Institute of Mathematics and Institute of Applied Mathematics of China Academy of Sciences, chairman and honorary chairman of Chinese Mathematical Society, director of National Mathematical Competition Committee, foreign academician of American National Academy of Sciences, academician of Third World Academy of Sciences, academician of Bavarian Academy of Sciences of the Federal Republic of Germany, deputy director, vice president and presidium member of physics department, mathematics and chemistry of China Academy of Sciences, director and vice president of mathematics department of China University of Science and Technology, vice chairman of China Association for Science and Technology, and member of the State Council Academic Degree Committee. He was a member of the first to sixth the NPC Standing Committee and vice-chairman of the sixth China People's Political Consultative Conference. He was awarded an honorary doctorate by Nancy University in France, The Chinese University of Hong Kong and the University of Illinois in the United States. Mainly engaged in the research and teaching of analytic number theory, matrix geometry, typical groups, automorphic function theory, multiple complex variable function theory, partial differential equations, high-dimensional numerical integration and other fields, and has made outstanding achievements. In the 1940s, the historical problem of Gaussian complete trigonometric sum estimation was solved, and the best error order estimation was obtained (this result is widely used in number theory). The results of G.H. Hardy and J.E. Littlewood on the Welling problem and E. Wright on the Tully problem have been greatly improved and are still the best records.
Since 1960s, he has applied mathematical methods to practice, screened out optimization methods and overall planning methods aiming at improving work efficiency, and achieved remarkable economic benefits.
Comrade Hua is a contemporary self-taught master of science and a world-famous mathematician. He is the founder and pioneer of China's research on analytic number theory, canonical group, matrix geometry, automorphic function theory and multiple complex variable function theory. It laid the foundation for matrix geometry in the future.
