Abstract

This paper is concerned with planar traveling wavefronts of mono-stable reaction-diffusion equations in \mathbb{R}^n ( n\geq2 ). We show that the large time behavior of the disturbed fronts can be controlled by two functions, which are the solutions of the specified nonlinear parabolic equations in \mathbb{R}^{n-1} , and the planar traveling fronts are asymptotically stable in L^\infty(\mathbb{R}^n) under ergodic perturbations, which include quasi-periodic and almost periodic ones as special cases.
