Solutions of the Differential Inequality with a~Null Lagrangian: Regularity and Removability of Singularities

A. A. Egorov

We prove a theorem on self-improving regularity for derivatives of solutions of the inequality $F(v^{\prime }(x))\le KG(v^{\prime }(x))$ constructed by means of a quasiconvex function $F$ and a null…
