Abstract:
This paper deals with the existence of traveling wave fronts of spatially
discrete reaction-diffusion equations with delay on lattices with general
dimension. A monotone iteration starting from an upper solution is
established, and the sequence generated from the iteration is shown to
converge to a profile function. The main theorem is then applied to a
particular equation arising from branching theory.
