Abstract

We obtain the classical global Lp , 2 ≦ p < ∞, estimate for the spatial gradient of the weak solutions for a class of parabolic problems in a very general irregular domain whose model is a nonlinear parabolic equation in divergence form. We treat discontinuous nonlinearity of BMO type and δ-Reifenberg flat domains. These domains might have fractal boundaries.
