Ill-posed Variational Problems and Regularization Techniques : Proceedings of the “Workshop on Ill-Posed Variational Problems and Regulation Techniques” held at the University of Trier, September 3-5, 1998

This book presents recent developments in the field of ill-posed variational problems and variational inequalities, covering a large range of theoretical, numerical and practical aspects. The main topics are: - Regularization techniques for equilibrium and fixed point problems, variational inequalities and complementary problems, - Links between approximation, penalization and regularization, - Bundle methods, nonsmooth optimization and regularization, - Error Bounds for regularized optimization problems
