A strongly coupled elliptic system under the homogeneous Dirichlet boundary condition denoting the steady-state system of the Lotka-Volterra two-species competitive system with cross-diffusion effects is considered.By using the implicit function theorem and the LyapunovSchmidt reduction method,the existence of the positive solutions bifurcating from the trivial solution is obtained.Furthermore,the stability of the bifurcating positive solutions is also investigated by analyzing the associated characteristic equation.
This paper is concerned with travelling front solutions to a vector disease model with a spatio-temporal delay incorporated as an integral convolution over all the past time up to now and the whole one-dimensional spatial domain R.When the delay kernel is assumed to be the strong generic kernel,using the linear chain techniques and the geometric singular perturbation theory,the existence of travelling front solutions is shown for small delay.
This paper is concerned with the diffusive Nicholson’s blowflies equation with nonlocal delay incorporated as an integral convolution over the entire past time up to now and the whole one-dimensional spatial domain R.Assume that the delay kernel is a strong generic kernel.By the linear chain techniques and the geometric singular perturbation theory,the existence of travelling front solutions is shown for small delay.
