Hua's early research field was analytic number theory, and his achievements in analytic number theory were particularly famous. The internationally famous "China Analytic Number Theory School" is a school initiated by China, which has made many significant contributions to the distribution of prime numbers and Goldbach conjecture.
Hua is also the founder and pioneer in the research of analytic number theory, matrix geometry, canonical group and automorphism function theory in China.
China's research on the theory of multiple complex variables and canonical group theory is ahead of the western mathematics field 10 years, and it is an internationally famous "canonical group China school".
Hua initiated the China School of Mathematics and brought it to the world level.
The international mathematical research achievements named after Fahrenheit include Fahrenheit Theorem, Huai-Hua Inequality, Fahrenheit Inequality, Laugar Theorem, Fahrenheit Operator, Hua-Wang Method and so on.
In the 1940 s, Hua solved the historical problem of Gaussian complete triangular sum estimation and obtained the best error order estimation. The research results of G·H· Hardy and J·E· Littlewood on the Welling problem and E Wright on the Tali problem have been greatly improved, and the research results of trigonometry are called "Fahrenheit Theorem" by the international mathematical community.
In algebra, Hua proved the basic theorem of one-dimensional projective geometry left over from history for a long time; This paper gives a simple and direct proof that the normal child of an object must be contained in its center, which is Hua theorem.
In cooperation with professors, Hua has made important achievements in the application research of modern number theory methods, which is called "Hua-Wang method".
Early academic career
Hua Yu 193 1 Studying and working in Tsinghua University. It took him only one and a half years to complete all the courses in the Department of Mathematics, and at the same time taught himself English, French, German and Japanese, and published three papers in international academic magazines. 1933 was appointed as a teaching assistant by Xiong qinglai, and1934 was promoted to a lecturer in September.
1935, Norbert Wiener visited China, noticed China, and strongly recommended it to the famous British mathematician at that time. Hua Yu 1936 visited Cambridge University and was influenced by Hardy School. He benefited a lot and published at least 15 papers there.
He returned to China from 1937 and served as a full professor in Tsinghua University until 1945, during which he experienced the The National SouthWest Associated University period. 1946 visited the Soviet union from February to May, and visited Princeton Institute for Advanced Studies in September. 1948 was employed as a full professor by the University of Illinois until 1950. In the same year, he was elected as an academician of Academia Sinica 1 Session (Mathematical Science Group).
His achievements in analytic number theory are particularly famous, and his contribution to the theory of multiple complex variables has influenced the development of mathematics in the world. He is the author of Fahrenheit Theorem, Brouwer-Gadang-Hua Theorem, Hua-Wang Law, Fahrenheit Identity and Fahrenheit Lemma.
