Almost periodic solution of a modified leslie-gower predator-prey model with beddington-deangelis functional response

We consider a predator-prey model with modified leslie-gower and beddington-deangelis functional response. by applying the comparison theorem of the differential equation and constructing a suitable lyapunov function,sufficient conditions which guarantee the permanence and existence of a unique globally attractive positive almost periodic solution of the system are obtained. our results not only supplement but also improve some existing ones. one example is presented to verify our main results. © 2013 zhimin zhang.
