### On the higher integrability for certain nonlinear problems

#### Abstract

We prove local higher integrability for gradients of solutions to a large class of elliptic equations of the type $\text{div} A(x,\nabla u) = 0$ by studying the deviation, in a suitable sense, of the operator $A$ to be constant with respect to $x.$
