报告摘要：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.
