## Solutions of the differential inequality with a null Lagrangian: higher integrability and removability of singularities. II.(English)Zbl 1420.30006

Summary: The aim of this paper is to establish a result on removability of singularities for solutions of the differential inequality with a null Lagrangian. Also, we obtain integral estimates for wedge products of closed differential forms and for minors of a Jacobian matrix.
