Continuity up to the boundary for obstacle problems to porous medium type equations

Kristian Moring, Leah Schätzler

Published 2023-06-09Version 1

We show that signed weak solutions to obstacle problems for porous medium type equations with Cauchy-Dirichlet boundary data are continuous up to the parabolic boundary, provided that the obstacle and boundary data are continuous. This result seems to be new even for signed solutions to the (obstacle free) Cauchy-Dirichlet problem to the singular porous medium equation, which is retrieved as a special case.
