Abstract

We describe a mathematical model for a three species ecological model which consists a prey (x1) and two neutral predators (x2, x3), surviving on the common prey (x1). Here all the three species have limited own natural resources. A Distributed type of delay is included in the prey (x1) species. The system is described by a couple of integro differential equations. The co-existing state is identified and the local stability analysis is studied at this state. Global stability is assured by choosing suitable Lyapunov's function. The effect of time delay is studied using Numerical simulation with different kernel strengths and it is proved that delays destabilizes the system.
