Traveling fronts for a delayed reaction-diffusion system with a quiescent stage

摘要

In this paper, we study the traveling wave fronts of a delayed reaction-diffusion system with a quiescent stage for a single species population with two separate mobile and stationary states. By transforming the corresponding wave system into a scalar delayed differential equation with an integral term, we establish the existence of the minimal wave speed c_(min), and the asymptotic behavior, monotonicity and uniqueness (up to a translation) of the traveling wave fronts. In particular, the effects of the delay and transfer rates on the minimal wave speed are studied.
