Semi-smooth Newton methods for variational inequalities of the first kind
ESAIM: Modélisation mathématique et analyse numérique, Tome 37 (2003) no. 1, pp. 41-62.

Semi-smooth Newton methods are analyzed for a class of variational inequalities in infinite dimensions. It is shown that they are equivalent to certain active set strategies. Global and local super-linear convergence are proved. To overcome the phenomenon of finite speed of propagation of discretized problems a penalty version is used as the basis for a continuation procedure to speed up convergence. The choice of the penalty parameter can be made on the basis of an L estimate for the penalized solutions. Unilateral as well as bilateral problems are considered.
