Ethnic group 1994 promoted professor: characters experience, Han nationality, lecture course, research direction, main contributions, academic achievements, scientific research projects, postgraduate training, representative works, award-winning records, characters experience 1982 graduated from the Mathematics Department of Shanxi University. 1982-2002 Teaching in Shanxi University. In 2002, he received a doctorate from the Chinese University of Hong Kong. 65438+July 0993-65438+February 0993 was invited by Australian National University as a visiting scholar for scientific research cooperation. 1997may-199711was invited as a visiting professor of scientific research cooperation by the University of Valencia, Spain. 199810-1999 was invited by Ohio state university in March as a visiting scholar for scientific research cooperation. From 2002 to 2004, at the invitation of the Chinese University of Hong Kong, we cooperated in scientific research. Now he is a professor and doctoral supervisor of Shanghai University. Academic * * *:: > Commentator. Teaching advanced algebra, modern algebra, matrix theory and advanced mathematics (undergraduate). Algebra, finite group theory, permutation group, nilpotent group and solvable group, etc. Research direction: finite group theory, combinatorial group theory. He has been engaged in the study of finite groups for many years, popularized the famous Brauer-Suzuki theorem on the existence of subgroups of normal complements, and studied the existence of normal complements for the first time from the dual angle of usual research, which provided a new research way for the study of normal complements. In the study of solvable groups, a conjecture put forward by the famous group theory expert Durkins was solved. In recent years, he has been engaged in the research on the influence of minimal subgroups on the structure of finite groups, and unified and popularized the famous burnside Theorem and Ito Theorem, which laid the foundation for further characterization of some saturated groups. Scientific research project, 2002-2004, developing and applying local methods to study group structure and overcoming some problems, National Natural Science Foundation, 654.38+700 million. From 2003 to 2005, the nature of minimal subgroups and the structure of finite groups were supported by Shanghai Natural Science Foundation, with 50,000 yuan. From 2005 to 2007, the local properties of finite groups and dual saturated groups were supported by the National Natural Science Foundation of China. Postgraduate training (doctoral students) in Wang Junxin. Sun, Wang Lili and Hu Yusheng (Master students). Li Deyu, Li, Zhao and Guo Qiaoping (graduate students).
