Hua (191010 12-1June 198512), Han nationality, a world-famous mathematician, China's analytic number theory, matrix geometry, etc. The international achievements in mathematical research include Fahrenheit Theorem, Huai-Hua Inequality, Fahrenheit Inequality, Pu Lawwill-Gardiner Theorem, Fahrenheit Operator, Hua-Wang Method and so on. He made outstanding contributions to the development of mathematics in China. The famous American mathematician Bateman wrote: "Hua is China's Einstein, and he is enough to be an academician of all the famous academies in the world.". It is listed as one of the 88 great mathematicians in the world in the Chicago Museum of Science and Technology. 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-suffering from typhoid fever at the age of 0/8, resulting in disability of the left 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 honorary doctorates 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 they 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. [Edit this paragraph] contributed to the "Overall Planning Method Pinghua" and "Optimization Method Pinghua". With easy-to-understand language and vivid methods, women and children can understand and master the application, achieving the effect of increasing production, improving quality and reducing consumption. Hua is known as "the people's mathematician". During this period, he also cooperated with Professor Wang Yuan to carry out the application research of modern number theory method in approximate analysis, and the obtained result was called "Hua Wang Fa". Two popular science books, Optimization Method Platform and its Supplement, and Master Planning Method are easy to understand and its Supplement, have been written in easy-to-understand language, which have been well received by the majority of workers in China. He brilliantly summed up the experience of popularizing mathematical methods for many years, and put forward and solved the purpose, content and method of popularizing mathematical methods. That is, what he called the "three principles", that is, (1) for whom? (2) What technology? (3) How to promote it? [Edit this paragraph] Professor Hua, an honorary professor, has made extensive and groundbreaking research work in the field of mathematics, publishing more than 65,438+050 papers and 65,438+00 books. 1985, Shanghai Education Publishing House published Hua, and held a book presentation ceremony in Beijing Science Society.
