题  目：On the maximum number of periodic solutions for higher dimensional systems

报告人：韩茂安 教授（上海师范大学）

摘  要： In this paper, we study the problem of the maximum number of zeros of vector analytic real functions with a small parameter based on higher dimensional generalization of Rouch ́e's theorem from complex analysis. Then using the obtained result we study the maximum number of periodic solutions for higher dimensional systems. Finally we present an application to autonomous systems.
