Abstract:

We consider a weak solution to the non-linear, parabolic systems $u_t-\text{div} \,A(x,t,u,Du)=0$, where the vector field $A$ satisfies a Dini-type continuity condition with respect to the variables $(x,t,u)$, and we prove a partial regularity result for such a solution. Moreover, we give an estimate of the size of the singular set of a solution in terms of a generalized parabolic Hausdorff measure associated to an appropriate modulus of continuity naturally associated to the coefficients of the system.
