Free boundary regularity in nonlinear one-phase Stefan problem

Analysis of PDEs 2024-04-11 v1

Abstract

We study the regularity of the free boundary in one-phase Stefan problem with nonlinear operator. Using the Hodograph transform and a linearization technique, we prove that flat free boundaries are C1,αC^{1, \alpha} in space and time. When the operator is concave (or convex) and smooth, the free boundary is smooth.
