چکیده

In this paper, we revisit a diffusive Leslie–Gower predator–preymodel with Holling-type II functional responses and Dirichlet boundary condition. It is shown that multiple positive steady state solutions exist under certain conditions on the parameters, while for another parameter region, the positive steady state solution is unique and locally asymptotically stable. Results are proved by using bifurcation theory, fixed point index theory, energy estimates and asymptotic behavior analysis. © 2013 Elsevier Inc. All rights reserved.

Global stability and stationary pattern of a diffusive prey-predator model with modified Leslie-Gower term and Holling II functional response

This paper is concerned with a diffusive prey-predator model with modified Leslie-Gower term and Holling II functional response subject to the homogeneous Neumann boundary condition. Firstly, by upper and lower solutions method, we prove the global asymptotic stability of the unique positive constant steady state solution. Secondly, introducing the cross diffusion, we obtain the existence of no...

Hopf bifurcation analysis of a diffusive predator-prey model with Monod-Haldane response

In this paper, we have studied the diffusive predator-prey model with Monod-Haldane functional response. The stability of the positive equilibrium and the existence of Hopf bifurcation are investigated by analyzing the distribution of eigenvalues without diffusion. We also study the spatially homogeneous and non-homogeneous periodic solutions through all parameters of the system which are spati...

Stability, bifurcations and chaotic dynamics in a delayed hybrid tri-trophic food chain model with Holling type-II and Leslie-Gower type functional responses

In this paper the qualitative behaviour of a delayed tri-trophic food chain model with Holling type II and modified Leslie-Gower functional responses is studied. Condition for existence and local stability of the interior equilibrium of the model are derived. Hopf bifurcation analysis is discussed by considering gestation time delay as bifurcation parameter. Applying normal form method and cent...

Traveling waves in a diffusive predator–prey model with holling type-III functional response

We establish the existence of traveling wave solutions and small amplitude traveling wave train solutions for a reaction-diffusion system based on a predator–prey model with Holling type-III functional response. The analysis is in the three-dimensional phase space of the nonlinear ordinary differential equation system given by the diffusive predator– prey system in the traveling wave variable. ...
