Mathematician Wang Yuan
Hua (19 10 ~ 1985), mathematician, academician of China Academy of Sciences. 191010 65438 was born in Jintan, Jiangsu province, and 1985 12 died in Tokyo, Japan. Research field: analytic number theory? Typical group? Matrix geometry? Automorphic function theory? Multivariate complex variable function.

1924 graduated from Jintan middle school and studied hard. 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.

In algebra, the basic theorem of one-dimensional projective geometry left over from history for a long time is proved. 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. His monograph "On Prime Numbers of Pile Foundations" systematically summarizes, develops and perfects Hardy and Littlewood's circle method, vinogradov's triangle sum estimation method and his own method. Its main achievements still occupy the leading position in the world after more than 40 years of publication, and have been translated into Russian, Hungarian, Japanese, German and English, becoming one of the classic works of number theory in the 20th century. His monograph "Harmonic Analysis on Typical Fields of Multiple Complex Variables" gives the complete orthogonal system of typical fields with accurate analysis and matrix skills, combined with group representation theory, and thus gives the expressions of Cauchy and Poisson kernel. This work has a wide and deep influence on harmonic analysis, complex analysis and differential equations, and won the first prize of China Natural Science Award. Advocating the development of applied mathematics and computer, he has published many works such as Master Planning Method and Optimization Research, which have been popularized in China. In cooperation with Professor Wang Yuan, he has made important achievements in the application research of modern number theory methods, which is called "Hua Wang Fa". He made great contributions to the development of mathematics education and the popularization of science. He has published more than 200 research papers and dozens of monographs and popular science works.

Chen Jingrun (1933 ~ 1996), mathematician, academician of China Academy of Sciences. 1933 was born in Fuzhou, Fujian on May 22nd. 1953 graduated from the Mathematics Department of Xiamen University. From 65438 to 0957, he entered the Institute of Mathematics of China Academy of Sciences and studied number theory under the guidance of Professor Hua. He has been a researcher at the Institute of Mathematics of China Academy of Sciences, a member of the academic committee, a professor at Guiyang University for Nationalities, Henan University, Qingdao University, Huazhong University of Science and Technology and Fujian Normal University, a member of the Mathematics Discipline Group of the State Science and Technology Commission, and the editor-in-chief of Mathematics Quarterly. Mainly engaged in the research of analytic number theory, and achieved international leading results in the research of Goldbach conjecture. This achievement is called "Chen Theorem" internationally and is widely cited.

Major achievements:

1On June 7th, 742, the German mathematician Goldbach put forward an unproven mathematical conjecture that "any even number can represent the sum of two prime numbers", abbreviated as "1+ 1". This conjecture is called Goldbach conjecture. China people opened the door of Goldbach's conjecture with new methods and won the championship, which attracted worldwide attention. This man is the first person in the world to conquer Goldbach's conjecture-Chen Jingrun. And by 20 15, no one can surpass him.

A famous mathematician and winner of China Mathematics Prize (1930-) mainly studies analytic number theory.

Hua, winner of the Mathematics Prize, is a researcher at the Institute of Mathematics, China Academy of Sciences. He used to be the director of the Institute of Mathematics of China Academy of Sciences, the director of the research office, the director of the academic committee of the Institute, the chairman of the Chinese Mathematical Society, the editor-in-chief of Mathematical Magazine, the editor-in-chief of Analytical Magazine of the Federal Republic of Germany, and the consultant of Singapore World Science Publishing House. 1980, Wang Yuan was elected as an academician of China Academy of Sciences (then known as a member of the Faculty).

In 1950s and 1960s, Wang Yuan applied the screening method in analytic number theory to the study of Goldbach conjecture for the first time, and proved propositions 3+4, 1957 and 2+3. Wang Yuan's 2+3 proof means that every sufficiently large even number can be expressed as the product of at most two prime numbers plus the product of at most three prime numbers. This is the first time that China scholars have leapt to the leading position in this research field. Its achievements are frequently cited by relevant literature at home and abroad. Wang Yuan was only 27 years old at this time. Later, he cooperated with China to study the application of number theory in approximate analysis. The theorem they proved in 1973 has been highly praised by the international academic community and is called the King of China Method. At the end of 1970s, the achievements in this field were systematically summarized, which had a wide international influence. In 1980s, Schmidt theorem was extended to any algebraic number field in Diophantine analysis, that is, advanced results were obtained in Diophantine inequality system.

Wang Yuan is not only a scientist who has made outstanding achievements in the field of mathematics, but also pays attention to the essence of mathematics, the influence of mathematics and mathematicians on education, society and human development through mathematical research, analyzes the scientific nature of mathematics in a simple way, and makes the public feel the fun of mathematics. He collected some thoughts in this field in Essays, Wang Yuan's Goldbach Conjecture, Biography of China, Collected Works of Wang Yuan, and China's Mathematical Career. Professor Wang Yuan mentioned the beauty of mathematics in his article: What is good mathematics? What are the criteria for evaluating mathematics? "The evaluation criteria of mathematics, like art, are mainly aesthetic criteria. Aesthetic standard is also very important for physical science, but it is the first standard for mathematics. Hua Luogeng can be said to be a masterpiece of popular science creation. It took eight or nine years to write a biography of mathematicians. The biography of another famous mathematician written by a famous mathematician is unique in this book.
