Calderón-Zygmund estimates for parabolic systems with p-growth and non-divergence data
Pêdra Andrade, Kristian Moring
Abstract
We obtain Calderón--Zygmund estimates for weak solutions to nonlinear parabolic systems with polynomial p-growth and the right-hand side in non-divergence form. Our approach does not require differentiability of the vector field with respect to the gradient variable and provides a unified treatment of both the singular and degenerate regimes. In particular, we establish local higher-integrability estimates for the gradient of the solution under appropriate dependency on the integrability of the right-hand side.
