Convex hull property for elliptic and parabolic systems of PDE

Analysis of PDEs 2023-11-29 v1

Abstract

We study the convex hull property for systems of partial differential equations. This is a generalisation of the maximum principle for a single equation. We show that the convex hull property holds for a class of elliptic and parabolic systems of non-linear partial differential equations. In particular, this includes the case of the parabolic pp-Laplace system. The coupling conditions for coefficients are demonstrated to be optimal by means of respective counterexamples.
