Jiang Lifu (1890— 1978), mathematician and mathematics educator. Founder of Mathematics Department of Nankai University. He used to be the director of the Institute of Mathematics of Academia Sinica.
It has made important contributions to the development of modern mathematics teaching and research in China. Jiang Lifu's academic career began with the study of synthetic geometry.
Since the 1940s, Jiang Lifu's research topic has been mainly the geometry of circular elements and spherical elements, and he has gradually sorted out a set of new methods with the second-order symmetric square matrix as the circular coordinate and the second-order Hermite square matrix as the spherical coordinate.
2. Xiong Qinglai
Xiong Qinglai (1September, 8931-1February 3, 969), a native of Xizai Village, Maitreya City, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, was a pioneer of modern mathematics in China and one of the main pioneers of China's function theory. He entered the history of world mathematics with the theory of "bear infinity"
Xiong qinglai mainly engaged in the research of function theory, and defined an "infinite order function", which is called "Xiong's infinite number" internationally. Xiong Qinglai has made great achievements in the field of "Functionalism".
1932 first represented China at the International Congress of Mathematicians in Zurich, Switzerland. 1934, his thesis "On Integral Functions and Meromorphic Functions of Infinite Order" was published, which enabled him to obtain a French national doctorate and became the first China person to obtain this degree.
In this paper, the "infinite order function" defined by Xiong Qinglai, known internationally as "Xiong's infinite number", has been recorded in the history of world mathematics and established his position in the international mathematics field.
3. Su Qing Bu
Su (1September 23rd, 902-March 7th, 2003/KLOC-0), born in Pingyang, Wenzhou, Zhejiang Province, was originally from Quanzhou, Fujian Province. He was an academician of China Academy of Sciences, a famous mathematician and educator in China, and the founder of China School of Differential Geometry. He is known as "the brilliant star of mathematics in the East", "the first geometer in the East" and "the king of mathematics".
He founded the China School of Differential Geometry and opened up a new research direction of computational geometry in his later years. ?
He has made outstanding contributions to affine differential geometry, projective differential geometry, general spatial differential geometry and projective yoke network theory, and established the internationally recognized China School of Differential Geometry. At the age of 70, a new research direction of computational geometry was founded and started in combination with solving the practical problems of mathematical lofting of ships. ?
Su's research direction is mainly differential geometry. Most of Su's research work belongs to affine differential geometry and projective differential geometry.
In addition, he also devoted himself to the study of general spatial differential geometry and computational geometry. He founded the internationally recognized School of Differential Geometry of Zhejiang University.
4. Chen Jingrun
Chen Jingrun (1933-65438 May 22 +0996 March 19), male, Han nationality, independent, from Fuzhou, Fujian, is a contemporary mathematician.
From 65438 to 0957, Chen Jingrun was transferred to the Institute of Chinese Academy of Sciences. As a new starting point, he studied harder. After 10 years of calculation,1May, 966, he published the paper "Representing even numbers as the sum of the products of a prime number and no more than two prime numbers".
The publication of the paper has been highly valued and praised by the world mathematics community and famous mathematicians. British mathematician Haberstein and German mathematician Li Xite wrote Chen Jingrun's paper into a math book called "Chen Theorem".
5. Hua
Hua (1910.1.12-1985.6.12) is a native of Jintan District, Changzhou, Jiangsu, and his ancestral home is Danyang, Jiangsu. Mathematician, academician of China Academy of Sciences, 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. Member of the 1st-6th the NPC Standing Committee of China.
He is the founder and pioneer of China's analytic number theory, matrix geometry, canonical group, automorphism function theory and multivariate complex function theory, and is listed as one of the 88 great mathematicians in Chicago Science and Technology Museum.
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.
In the 1940s, the historical problem of Gaussian complete triangular sum estimation was solved, and the best error order estimation was obtained. 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, 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.
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".
