On some difference approximations and regularization of optimal control problems for quasilinear elliptic equations for inhomogeneous anisotropic medium with controls involved coefficients

In the present paper, we construct difference approximations of optimal control problems for quasilinear elliptic equations with controls involved in coefficients. Accuracy estimates of these approximations with respect to the state and the objective functional are obtained. The approximations are regularized after Tikhonov
