Global stability of traveling wave fronts for non-local delayed lattice differential equations

摘要

This paper is concerned with the global stability of traveling wave fronts of a non-local delayed lattice differential equation. By the comparison principle together with the semi-discrete Fourier transform, we prove that, all noncritical traveling wave fronts are globally stable in the form of t- ~(1α)e- ~(μt) for some constants μ>0 and 0<α≤2, and the critical traveling wave fronts are globally stable in the algebraic form of t- ~(1α).
