A comparison principle for a class of doubly nonlinear parabolic fractional partial differential equations
Michael Strunk
In this paper, we establish a comparison principle for non-negative weak solutions to a class of doubly nonlinear parabolic fractional partial differential equations within a space…

Boundary regularity for parabolic systems with nonstandard -growth conditions in smooth convex domains
Michael Strunk
We study the boundary regularity of local weak solutions to nonlinear parabolic systems of the form \begin{equation*} \partial_t u^i - \mathrm{div} \big( a(|Du|) Du^i \big)= f^i, \…
