| Abstract: | In this paper, we analyze the dynamics of a delayed predator-prey system in the presence of harvesting. This is a modified version of the Leslie-Gower and Holling-type II scheme. The main result is given in terms of local stability, global stability, influence of harvesting and bifurcation. Direction of Hopf bifurcation and the stability of bifurcating periodic solutions are also studied by using the normal form method and center manifold theorem. |
