Periodicity of Nonautonomos n-Species Cooperative System with Feedback Controls

摘要

In this paper, a non-autonomous n-Species Lotka-Volterra cooperative system with feedback controls is investigated. By using Comparability Theorem, constructing Lyapunov function and Continuation Theorem, a set of easily verifiable sufficient conditions are obtained to guarantee the permanent and positive periodic solution, and achieve global attractivity of the system. Finally an example is given as the application of theorem.
