1in June, 950, the new China Academy of Sciences was established soon, and when everything was ready, it set out to set up the Institute of Mathematics. The preparatory office is located at No.3 Street, with the famous mathematician Su Ren as the director, Zhou Peiyuan, Hua and Xu as the deputy directors and Tian Fangzeng as the secretary. The preparatory work has been highly valued by the Central People's Government. 1 951June1day, the State Council approved the appointment of the director of Huawei's upcoming Institute of Mathematics. 1952, 1 In July, the Institute of Mathematics was formally established, located in Tsinghua Campus, and established the policy of coordinated development of pure mathematics and applied mathematics. The earliest research groups are number theory, differential equations, mechanics, computer development, probability and statistics, algebra, topology and so on.

1953 in the first half of the year, there were 32 researchers in the Institute of Mathematics, including 5 full-time researchers. Of these 32 people alone, 17 were later elected as academicians of China Academy of Sciences. From 65438 to 0956, through the formulation of the long-term plan for the development of science and technology in China in 12 years, the Institute of Mathematics ensured the coordinated development of all important directions of mathematics, while focusing on the development of differential equations, probability statistics and other branches closely related to the national economy and national defense construction. At the same time, functional analysis, mathematical logic and other research groups were set up to strengthen the research of corresponding theoretical disciplines. 1957 Mr. Xiong Qinglai, who came back from French, was responsible for establishing the research group of function theory. In the same period, the research work related to mechanics and computer development went out independently, and the Institute of Mechanics and the Institute of Computing Technology of Chinese Academy of Sciences were established respectively. Inspired by the 12-year long-term plan for the development of science and technology, the Institute of Mathematics embarked on a scientific road.

1956, China awarded the first national natural science award. Among all the three first prizes, mathematics won two prizes, namely, Hua's Theory of Functions of Multiple Complex Variables on Typical Fields and Wu Wenjun's Research on Indicator Class and Indicator Class.

During this period, the position of the Institute of Mathematics has changed. 1957 temporarily moved to Xiyuan Hotel, 1958 moved to Zhongguancun (now the North Building of Institute of Computing Technology).

196 1 Set up research laboratories according to disciplines, including four disciplines (number theory, algebra, geometry, topology), function theory, differential equations, functional analysis, mathematical logic, theoretical physics, probability statistics, as well as the operational research laboratory, with two research laboratories, namely, mechanics and mathematics, which were initiated by Qian Xuesen, Hua and Xu Guozhi. 1962 Due to the needs of national projects, a control theory laboratory led by Guan He and Song Jian was newly established. Then the mechanical laboratory was reset. All kinds of research work is progressing rapidly.

1966 After the Cultural Revolution began, the research work came to a standstill. From 65438 to 0972, Premier Zhou Enlai's instruction on strengthening the research of basic theory made the mathematics research work start again. 1973, Chen Jingrun officially published his research on Goldbach's conjecture; From 65438 to 0975, Yang Le and Zhang Guanghou published their research on the theory of value distribution. The finite element method was founded by Feng Kang and others independently of the West in the early 1960s, and has been widely used in many departments of national economy and national defense construction. These representative works show the world the landmark achievements made by researchers in the Institute of Mathematics under extremely difficult conditions. 1976 After the downfall of the Gang of Four, especially the convening of the 1978 National Science Conference ushered in the spring of science. In the atmosphere of respecting knowledge and talents, the researchers of the Institute of Mathematics strive to catch up with the international frontier of mathematics, and the work in all fields of pure mathematics and applied mathematics has been comprehensively and rapidly promoted and embarked on the track of healthy development.

1977 China academy of sciences has set up a computing center with computational mathematics as its main research object (1995 was changed to the Institute of Computational Mathematics and Scientific Engineering Computing), and its address is No.4 Nansi Street, Zhongguancun. At the end of 1979, according to the decision of the Chinese Academy of Sciences, someone set up the Institute of Systems Science from the Institute of Mathematics, engaged in the research of cybernetics, operational research, statistics, systems engineering and related marginal disciplines of mathematics. Some researchers from the Institute of Mathematics merged with those from the former Office for the Promotion of Applied Mathematics of China Academy of Sciences to form the Institute of Applied Mathematics. Mathematics focuses on basic theoretical research, taking into account applied mathematics, computer science and other directions. 1982, when the state resumed awarding natural science awards, the four major research institutes once again attracted social attention with high-level achievements. 199 1 Address moved toNo. Nansi Street, Zhongguancun 1.

199865438+In February, under the impetus of the knowledge innovation project of China Academy of Sciences, the Institute of Mathematics, the Institute of Applied Mathematics, the Institute of System Science and the Institute of Computational Mathematics and Scientific Engineering Computing were integrated into the Institute of Mathematics and System Science.
