Liu Yingming, mathematician, born in Oct., 1940 in Fuzhou, Fujian Province. Graduated from Department of Mathematics and Mechanics of Peking University in 1963 and since then a faculty member of Department of Mathematics, Sichuan University (SCU) until now. He became a professor (1983), vicepresident of SCU (1989-2005), dean of Graduate School of SCU (2000-2005) and honor dean now. He was elected the academician of CAS in 1995. He is chief professor of Yangtze Math. Research Center of SCU. He is a member of Standing Committee of National Peoples Congress (NPC) and deputydirector of the Committee of Education, Science, Culture and Health of NPC; vicepresident of Peoples Political Consultative Conference (PPCC) of Sichuan Province; vicepresident of Central Committee of Jiu San (Sept. 3rd) Society; member of Academic Degree Committee of State Council，and member of its Appraisal Group of Math. since 1985; head of Math. and System Science Experts Group, PostDoctorate State Administration Committee; council member and vicepresident (1993-1995) of International Fuzzy Systems Association (IFSA) and chairman of China Branch; director of Math. Research Center of Education Ministry of China; deputydirector of Chinese Society of Industry and Applied Math. He was a representative of 6th and 7th NPC; member of the Standing Committee, 8th PPCC of China and 9th NPC; deputydirector of the Chinese Math. Society (1995-2003).
His major research fields are topology and mathematical treatment on uncertainty (especially, fuzziness). In 2005, because of his distinguished contribution in the fuzzy systems field, he became IFSA Fellow, awarded by IFSA.
He had profound investigation on basic topology structureneighborhood structure; and laid a foundation of the pointed school of “topology on lattices”. He made breakthrough in several difficult questions, such as imbedding theory, compactification theory, the latticevalued HahnDieudonne Insertion Theorem, etc. Thus, the topology on lattices, established by the great mathematician Ehresmann, is advanced to a new stage. On algebraic topology, he solved the Whitehead Problem on CW complex. An expressive achievement on study of paracompactness was yielded. He also obtained answers on  LawsonMislove problems in domain theory; He yielded important results on algebra and order structure related with topology; Replacing “representation” by “approximation,” he got brief approximations of Kolmogorov representation for a class of nplace functions, and yielded a true decreasing dimension method. The work raised great interest of the experts of multiplevalued logic and artificial intelligence. He promoted the industrialization of fuzzy technique applications in China.
