Abstract
The Prey-Predator model involving Holling Type-II and Holling Type-III is investigated in detail in this paper. We begin our study by showing the positivity and boundedness of its positive solutions. The equilibria are calculated and their stability behavior are determined by means of linear stability analysis. Global stability of one of the equilibria, i.e., the interior equilibrium is investigated by means of Lyapunov function. We also provide the study of bifurcation in the model regarding the involvement of the Holling terms.
