The following are some famous mathematicians: Liu Hui (born around 250 AD) is a very great mathematician in the history of Chinese mathematics and also occupies a prominent position in the history of world mathematics. His representative works "Nine Arithmetic Notes" and "Calculation on the Island" are the most precious mathematical heritages of China. Jia Xian and Jia Xian were outstanding mathematicians in the Northern Song Dynasty in ancient China. The Nine Chapters of Yellow Emperor's Arithmetic Fine Grass (nine volumes) and Arithmetic Ancient Collection (two volumes) have been lost. His main contribution is to create the "Jiaxian Triangle" and the method of multiplication and multiplication, which is the positive root method for finding the higher power. At present, the principle and procedure of mixed division in middle school mathematics are similar, while the multiplication and division method is more neat, simple and programmed than the traditional method, so it shows its superiority, especially when it comes to high power. This method was put forward more than 700 years before the conclusion of European mathematician Horner. Qin Jiushao (about 1202- 126 1) was born in Anyue, Sichuan. Its most important achievements in mathematics-"the sum of large calculations" (a solution of congruence group) and "the solution of positive and negative square roots" (a numerical solution of higher-order equations) made this Song Dynasty arithmetic classic occupy a prominent position in the history of medieval mathematics. Ye Li Ye Li (1 192- 1279), formerly known as Li Zhi, was born in Luancheng in Jin Dynasty. His main purpose is to explain the method of making equations with celestial elements. "Astrology" is similar to the column equation method in modern algebra. "Let Tianyuan be so-and-so" is equivalent to "Let X be so-and-so", which can be said to be an attempt of symbolic algebra. Another mathematical work by Ye Li, Yi Gu Yan Duan (1259), also explains Heaven. Zhu Shijie (1300 or so), whose real name is Yanshan (near Beijing today), "traveled around the lake and sea with famous mathematicians for more than 20 years" and "gathered scholars by following the door" ("Mo Ruo and Zu Yi: Four Lessons"). Zhu Shijie's representative works in mathematics include "Arithmetic Enlightenment" (1299) and "Meeting with the Source" (1303). "Arithmetic Enlightenment" is a well-known mathematical masterpiece, which spread overseas and influenced the development of mathematics in Korea and Japan. "Meeting with the source of thinking" is another symbol of the peak of China's mathematics in the Song and Yuan Dynasties, among which the most outstanding mathematical creations are "thinking about the source" (formulation and elimination of multivariate higher-order equations), "superposition" (higher-order arithmetic progression summation) and "seeking differences" (higher-order interpolation). Zu Chongzhi (AD 429-500) was born in Hebei Province. He is not only a mathematician, but also familiar with astronomical calendar, machinery manufacturing, music and other fields, and is an astronomer. Zu Chongzhi's main achievement in mathematics is the calculation of pi. He calculated pi as 3. 14 159260, a >；; 0), the proof of "gravity difference technique" is given by using the area relation of geometric figures in the solar altitude map annotation. The method used by astronomers in the Han Dynasty to measure the height and distance of the sun is called gravity difference technique. Hua is a modern mathematician in China. 19101012 was born in Jintan county, Jiangsu province. 1June 1985 12 died in Tokyo, Japan. After graduating from junior high school, Hua 1924 studied in Shanghai China Vocational School for less than one year. He dropped out of school because of his poor family. He studies mathematics hard. 1930 He published an article on solving algebraic equations in Science, which attracted the attention of experts. He was invited to work in Tsinghua University and began to study number theory. 1934, 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. 1946 was invited by the Institute of Advanced Studies in Princeton, Soviet Union as a researcher and taught at Princeton University. From 65438 to 0948, he was a professor at the University of Illinois. 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. 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. After more than 40 years of publication, its main achievements still occupy the leading position in the world, and it has 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 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 of the Institute, 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. This work, together with Professor Wang Yuan and Professor Pan Chengdong, won the first prize of National Natural Science 1978. Later, the above theorem was improved, and the paper "The Minimum Prime Number in arithmetic progression" was completed at the beginning of 1979, which pushed the minimum prime number from the original 80 to 16, which was well received by the international mathematics community. The close relationship between combinatorial mathematics and modern economic management, scientific experiments, cutting-edge technology and human life is also studied. He has published more than 70 research papers, including "Interesting Talks on Mathematics" and "Combinatorial Mathematics"! Su (1902-2003) was born in Pingyang, Zhejiang. 1927 graduated from the Department of Mathematics, Tohoku Imperial University, Japan, and then entered the graduate school of this school, obtaining a doctorate in science. After returning to China, he was employed by the Mathematics Department of Zhejiang University. 1952 national college adjustment, he taught at Fudan University, and served as provost, vice president and principal. From 1983, he became honorary president of Fudan University. 1985 Honorary President of Wenzhou University. He has served as the vice chairman of the 7th and 8th China People's Political Consultative Conference, the Standing Committee of the 5th and 6th National People's Congress, and the vice chairman of NLD Central Committee. 1955 was elected as a member of the Department of Mathematical Physics of China Academy of Sciences and a member of the Standing Committee of the Academic Committee, specializing in differential geometry, and founded a recognized school of differential geometry at home and abroad. Author of "Introduction to Projective Curves", "Introduction to Projective Surfaces" and other monographs 10.
