A critical case of stability in a free boundary problem

A critical case of stability in a free boundary problem We study the stability of the planar travelling wave solution to a free boundary problem for the heat equation in the whole $ \Bbb R^2 $ . We turn the problem into a fully nonlinear parabolic system and establish a stability result which is the proper generalization of the one-dimensional case. The curvature terms contribute a gradient squared corresponding to critical growth. The latter is eliminated by means of the Hopf-Cole transformation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Evolution Equations Springer Journals

Abstract

We study the stability of the planar travelling wave solution to a free boundary problem for the heat equation in the whole $ \Bbb R^2 $ . We turn the problem into a fully nonlinear parabolic system and establish a stability result which is the proper generalization of the one-dimensional case. The curvature terms contribute a gradient squared corresponding to critical growth. The latter is eliminated by means of the Hopf-Cole transformation.
