Existence and global asymptotic stability of positive periodic solutions of w-species delay impulsive Lotka-Volterratype systems

摘要

In this paper, the existence and global asymptotic stability of positive periodic solutions of periodic n -species Lotka-Volterra impulsive systems with several deviating arguments are studied. By using the continuation theorem of coincidence degree theory and Lyapunov-Razumikhin method, sufficient conditions are obtained. Some known results are improved and generalized.
