Zhang Wenjun

Zhang Wenjun, Ph.D., postdoctoral, Professor of School of mathematics and computational science of Shenzhen University, part-time professor of Zhejiang University, part-time doctoral supervisor of Capital Normal University and Shantou University, and executive director of professional committee of educational mathematics of Chinese society of higher education, executive director of National Elementary Mathematics Research Association, executive director of Guangdong Mathematics Association, and executive director of Guangdong Elementary Mathematics Research Association President of Shenzhen mathematics society.

Character experience

In 1983, he graduated from the Department of mathematics of Henan University and stayed in the university to teach. After 1985, he successively obtained a master's degree and a doctor's degree of Science in China University of science and technology and Fudan University. In 1995, he was promoted to a professor. In 1996, he worked as a postdoctoral in China University of science and technology and entered Shenzhen University. Since 1997, he has been the director of the Department of mathematics of Normal University. In 2006, he has been in the current position. He was promoted to Professor in 1995 and transferred to Shenzhen University in 1996. He is the first Dean of School of mathematics and computational science of Shenzhen University, part-time professor of Zhejiang University and director of Guangdong Mathematics Association.

Lecture course

In terms of teaching work, he has taught more than ten undergraduate and postgraduate courses, such as mathematical analysis, complex function, real variable function and functional analysis, principles of accounting, theory of multiple complex variable function, and independently developed undergraduate courses, such as mathematics appreciation, teaching of mathematical open problems, and selected lectures of modern mathematics in the new curriculum.

Research direction

Multivariate complex analysis.

Main contributions

Student achievement

He has undertaken and successfully completed 19 national, provincial and ministerial scientific research projects, published more than 60 papers in important academic journals at home and abroad, and his achievements have been included in three international monographs; he has published one monograph in cooperation with others; six achievements have won municipal, provincial and national awards respectively; he has compiled one set of mathematics textbooks for junior high school and senior high school in Hong Kong, and participated in the compilation of one kind of elective textbook for senior high school new curriculum of PEP a edition. The second batch of excellent teachers in Guangdong Province were selected as the top ten in Guangdong Province.

Educational research

In scientific research, in the field of multi complex geometric function theory, he successively established the growth theorem and covering theorem of star type mapping on the unit ball in general Banach space, the deviation theorem of convex mapping, gave the decomposition theorems of unit ball in CN, some convex mapping on Reinhardt field and quasi convex mapping, and gave the decomposition theorems of quasi convex mapping on unit multi cylinder in CN In the field of Analytic Dynamical Systems with multiple complex variables, he has successively given complete dynamical characterizations of holomorphic self maps over general strongly quasiconvex and smooth weakly quasiconvex domains in CN. These results are still one of the best results in this direction, and have been cited many times by others. In the field of asymptotic analysis, he and his collaborators have improved Riemann Hilbert method, which has some advantages It overcomes the defect that the original method can't get the uniform asymptotic expansion, and obtains the uniform asymptotic expansion of Jacobi polynomials whose parameters vary with degree.

Award winning record

He won the first prize of classroom teaching in Shenzhen University for two consecutive times.
