The evolving surface Cahn-Hilliard equation with a degenerate mobility

Analysis of PDEs 2025-08-04 v3

Abstract

We consider the existence of suitable weak solutions to the Cahn-Hilliard equation with a non-constant (degenerate) mobility on a class of evolving surfaces. We also show weak-strong uniqueness for the case of a positive mobility function, and under some further assumptions on the initial data we show uniqueness for a class of strong solutions for a degenerate mobility function.
