Abstract

The aim of this work is to study the traveling wavefronts in a discrete-time integral recursion with a Gauss kernel in ℝ². We first establish the existence of traveling wavefronts as well as their precise asymptotic behavior. Then, by employing the comparison principle and upper and lower solutions technique, we prove the asymptotic stability and uniqueness of such monostable wavefronts in the sense of phase shift and circumnutation. We also obtain some similar results in ℝ.
