Fish–hook shaped global bifurcation branch of a spatially heterogeneous cooperative system with cross-diffusion

Abstract: In this paper, we will consider the following strongly coupled cooperative system in a spatially heterogeneous environment with Neumann boundary conditionwhere Ω is a bounded domain in R N (N 1) with smooth boundary ∂Ω; k is a positive constant, λ and μ are real constants which may be non-positive; b(x) ≡ 0 and d(x) ≡ 0 are continuous functions inΩ; ρ(x) is a smooth positive function inΩ with ∂ ν ρ(x)| ∂Ω = 0; ν is the outward unit normal vector on ∂Ω and ∂ ν = ∂/∂ν. For the case μ > 0, we show that if |μ| is … Show more

“…Hutson et al [10][11][12][13] studied spatial effects of birth rates in some diffusive competitive models. Wang et al [14] investigated a Lotka-Volterra cooperative system with cross-diffusion in a spatially heterogeneous environment. Applying the bifurcation theory and the Lyapunov-Schmidt reduction, they obtained the global bifurcation branch of positive steady states.…”
