Coexistence of steady state for a diffusive prey-predator model with harvesting

Blog Article

In caruso milk thistle this article, we study a diffusive prey-predator model with modified Leslie-Gower term and Michaelis-Menten type prey harvesting, subject to homogeneous Dirichlet boundary conditions.Treating the prey harvesting parameter as a bifurcation parameter, we obtain the existence, bifurcation and stability of coexistence princess polly dresses long sleeve steady state solutions.We use the method of upper and lower solutions, degree theory in cones, and bifurcation theory.The conclusions show the importance of prey harvesting in the model.
