Regularity of the free boundary in an unstable parabolic problem

Analysis of PDEs 2025-08-25 v1

Abstract

We study the free boundary in an unstable parabolic problem arising from a model in combustion. We consider the physical situation in which the heat advances and prove that the free boundary is a C1,α/2C^{1,\alpha/2} hypersurface.
