Data expansion:

Fahrenheit theorem is the research result of Hua, a famous mathematician in China. Fahrenheit theorem is that a semi-automorphism of a body must be automorphism, automorphism or anti-isomorphism. Mathematician Hua's research results on complete triangular sum are called "Fahrenheit theorem" by the international mathematics community; In addition, he and mathematician Wang Yuan put forward the approximate calculation method of multiple integrals, which is internationally known as the "King of China Method".

Character introduction:

Hua, a modern mathematician in China. 19101012 was born in Jintan county, Jiangsu province. Hua Yu 1924 After graduating from junior high school in Jintan Middle School, he studied in Shanghai China Vocational School for less than one year, but dropped out of school because of his poor family. However, he taught himself mathematics very hard. 1930, he published an article on solving algebraic equations in Science, and was invited to work in Tsinghua University, where he began the research of number theory.

65438-0934, became a researcher of China Education and Culture Foundation. 1936 went to Cambridge University as a visiting scholar. 1938 returned to China and was employed by Professor The National SouthWest Associated University. From 65438 to 0946, he went to the United States and worked as a researcher at Princeton Institute of Mathematics and Princeton University. From 65438 to 0948, he was a professor at the University of Illinois. 1950 Return to China.

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 Director of Chinese Mathematical Society, Director of National Mathematical Competition Committee, Foreign Fellow of American National Academy of Sciences and Fellow of Third World Academy of Sciences.

Academician of Bavarian Academy of Sciences, Federal Republic of Germany; Deputy Director, Vice President and Presidium Member of Physics, Mathematics and Chemistry Department of China Academy of Sciences; Director and Vice President of Mathematics Department of University of Science and Technology of China; Vice President of China Association for Science and Technology; member of the State Council Academic Degrees 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 are still the best records.
