- AbstractIn this paper we present a priori error estimates for the Galerkin solution of variational inequalities which are formulated in fractional Sobolev trace spaces, i.e. e H^(1/2) (Γ). In addition to error estimates in the energy norm we also provide, by in H applying the Aubin–Nitsche trick for variational inequalities, error estimates in lower order Sobolev spaces including L_2 (Γ). The resulting discrete variational inequality is solved by using a semi–smooth Newton method, which is equivalent to an active set strategy. A numerical example is given which confirms the theoretical results.
