Almost periodic solution for a Volterra model with mutual interference and Beddington–DeAngelis functional response

摘要

In this paper, we consider a Volterra model with mutual interference and Beddington–DeAngelis functional response. By applying the comparison theorem of the differential equation and constructing a suitable Lyapunov functional, sufficient conditions which guarantee the permanence and existence of a unique globally attractive positive almost periodic solution of the system are obtained.
