Abstract: The first part of the lecture deals with a description of the SCD (subspace containing derivative) mappings and the SCD semismooth* Newton method for the solution of general inclusions. This method is then applied to a class of variational inequalities of the second kind. As a result, one obtains an implementable algorithm exhibiting a locally superlinear convergence. Finally, we demonstrate the efficiency of a globalized version of this method via a Cournot-Nash equilibrium in which the objectives of the players (firms) are nonsmooth due to the presence of the so-called cost of change. The problem is modeled as a variational inequality of the second kind and, to test the performance of the applied method, one admits really large numbers of players and produced commodities. Joint work with: Helmut Gfrerer and Jan Valdman.
