Hopf bifurcation analysis in a diffusive predator–prey system with spatial heterogeneity and delays
In this paper, we consider a diffusive Lotka–Volterra predator–prey system with spatial heterogeneity and two delays. We first show that there exists a nonconstant positive steady state when the diffusion rate...
