Stability and higher integrability of derivatives of solutions in double obstacle problems
The paper deals with higher integrability of the derivatives of solutions to double obstacle problems associated with the second-order quasilinear elliptic equation \(\nabla\cdot A(x,\nabla u)=0\) under natural assumptions on obstacles. The result is used to prove a stability result for solutions to double obstacle problems for varying equations.
