Abstract
In this paper we consider a nonlinear parabolic equation of p(x, t)-Laplacian type in divergence form with measurable data over non-smooth domains. We establish the global Calderón–Zygmund theory for the weak solutions of such a problem in the setting of weighted Lebesgue spaces. The nonlinearity of the coefficients is assumed to be discontinuous with respect to (x, t)-variables and the lateral boundary of the domain is sufficiently flat beyond the Lipchitz category. As an application of the main result, the regularity in parabolic Morrey scales for the spatial gradient is also obtained.
