Calderón-Zygmund estimates for parabolic -Laplacian systems with non-divergence form right-hand sides

Pêdra Andrade, Verena Bögelein, Frank Duzaar +1

We establish local Calderón-Zygmund type estimates for weak solutions to nonlinear parabolic systems with -growth and VMO coefficients. In particular, we prove that if the righ…

Global higher integrability for systems with -growth structure in noncylindrical domains

Kristian Moring, Christoph Scheven, Leah Schätzler

We consider the Cauchy-Dirichlet problem to systems with -growth structure with , whose prototype is \begin{equation*} \partial_t u- \operatorname{div} \big( |Du…

Hölder regularity for degenerate parabolic double-phase equations

Wontae Kim, Kristian Moring, Lauri Särkiö

We prove that bounded weak solutions to degenerate parabolic double-phase equations of -Laplace type are locally Hölder continuous. The proof is based on phase analysis and met…
