Boundary regularity for parabolic systems with nonstandard $(p, q)$ -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, \…

Gradient regularity for widely degenerate parabolic equations

Michael Strunk

In this paper, we are interested in the regularity of weak solutions $u : Ω_{T} \to R$ to parabolic equations of the type \begin{equation*} \partial_t u - \mathrm{div} \nab…

Gradient regularity for widely degenerate elliptic partial differential equations

Michael Strunk

In this paper, we investigate the regularity of weak solutions $u : Ω \to R$ to elliptic equations of the type \begin{equation*} \mathrm{div}\, \nabla \mathcal{F}(x,Du) =…
