Sun‐Sig Byun, Lihe Wang · Discrete and Continuous Dynamical Systems · 2008
We obtain an optimal $W^{1,p}$, $2 \leq p < \infty$, regularity theory on the conormal derivative problem for a nonlinear parabolic equation in divergence form with small BMO nonlinearity in a $\delta$-Reifenberg flat domain.
