 The authors establish a series of optimal regularity results for solutions to general nonlinear 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. \[a(x,t,u,Du)\leq L(1+Du^{p1}), p \geq 2.\] They 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 CalderónZygmund estimates for nonhomogeneous problems are achieved here.
