A Positive Periodic Solution Of A Class Of Integral Differential Equations With Pulse System

The principle aim of this paper is to explore the existence of positive periodic solutions of a generalized ecological competition systems governed by impulsive intergro-differential equation with infinite delays.Easily verifiable sufficient criteria are established. The main results , which improve and generalize some known results in the literature.The tree of this paper is the following. Chapter one focuses on the background of the problem being investigated. Chapter two establishes easily verifiable sufficient criteria for the existence of positive periodic solutions of the generalized ecological competition system with impulse and infinite delay. In this chapter, applications to some famous competition models are also presented. The investigation shows that this result is more extensive and improves some results studied in the literature.
