Abstract:

A delayed diffusive predator-prey system with Ivlev-type predator functional response subject to Neumann boundary conditions is considered. The stability of nonnegative equilibria and existence of Hopf bifurcation are obtained by analyzing the distribution of the eigenvalues. By the theory of normal form and center manifold, an explicit algorithm for determining the stability and direction of periodic solution bifurcating from Hopf bifurcation is derived.

Key words: Prey-predator, Delay, Ivlev-type functional response, Hopf bifurcation, Periodic solutions
