| Research Abstract |
In this study, we analyzed the asymptotic stability of planar waves and the large time behavior of disturbed planar fronts that appear in a reaction diffusion equation with bistable type nonlinearity. We improved some previous results and showed the approximation theorem for the large time behavior of planar fronts based on the mean curvature flow. The motion of hypersurfaces governed by the mean curvature flow was also studied, and some sufficient conditions for the asymptotic stability of hyperplanes as traveling wave solutions were shown.
