Abstract

We establish a series of optimal regularity results for solutions to general non-linear parabolic systems \[ u_t- \mathrm {div} \ a(x,t,u,Du)+H=0\,, \] under the main assumption of polynomial growth at rate $p$ i.e. \[ |a(x,t,u,Du)|\leq L(1+|Du|^{p-1})\,,\qquad p \geq 2 \;. \] We give a unified treatment of various interconnected aspects of the regularity theory: optimal partial regularity results for the spatial gradient of solutions, the first estimates on the (parabolic) Hausdorff dimension of the related singular set, and the first Calderón-Zygmund estimates for non-homogeneous problems are here achieved.
