Free boundary regularity for the inhomogeneous one-phase Stefan problem

Analysis of PDEs 2026-04-28 v4

Abstract

In this paper, we prove that flat free boundaries of solutions to inhomogeneous one-phase Stefan problem are C1,αC^{1,\alpha}. The method consists of employing a hodograph transform and deriving the regularity via a linearization technique, following the approach introduced by De Silva, Forcillo, and Savin in \cite{DFS23}.
