Prey- Predator model with two time delay

In this paper a prey- predator model with two time delay based on Lotka- Volterra system of differential equation is introduced. In this model the number of prey at time t depends on the prey quantity in time t and t-t1, where _1 is prey during pregnancy. Also, the predator quantity at time t depends on the number of predator at time t and the number of prey at time t and t − t2, where t2 is predator during pregnancy. As follows, stability at equilibrium points are investigated
