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


Department: Department of Mathematics, Shanghai Normal University Shanghai,  200234, P.R.China


Abstract: 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 Rouche'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. .


Key words: Averaging method; bifurcation function; periodic  solution.
