Optimal regularity estimates for general nonlinear parabolic equations (Q2309419)

The authors consider a Cauchy-Dirichlet problem for a general quasilinear parabolic equation in a non-smooth domain. They provide a global Calderón-Zygmund property for the equation, extending the known elliptic result to the parabolic case, which is not trivial. In order to do this they develope a technique consisting on suitably combining several other approaches, overcoming the difficulties that the problem presents.
