摘要：
A particular approach is proposed to solve unilateral problems for elliptic operators in non-divergence form. The solution of such non-variational problems is approximated, via a regularization procedure, by the finite element solutions of certain associated variational inequalities. Convergence results and error estimates in the L infinity-norm are proved for such an approximation in the case of Holder continuous coefficients in the principal part of the operator.
