### Gradient estimates for a class of parabolic systems

#### Abstract

We establish local Calderón-Zygmund-type estimates for a class of parabolic problems whose model is the nonhomogeneous, degenerate/singular parabolic $p$-Laplacian system $u_t -\operatorname{div}(|Du|^{p-2}Du) =\operatorname{div}(|F|^{p-2}F),$ proving that $F \in L_\operatorname{loc}^{ q} \Longrightarrow Du\in L^{q}_\operatorname{loc},\quad \forall\,q\geq p.$ We also treat systems with discontinuous coefficients of vanishing mean oscillation (VMO) type
