Duality for Nonconvex Approximation and Optimization

The theory of convex optimization has been developing constantly over the past 30 years. Recently, researchers have been studying more complicated classes of problems that still can be studied by means of convex analysis, so-called "e;anticonvex"e; and "e;convex-anticonvex"e; optimization problems. This monograph contains an exhaustive presentation of the duality theory for these classes of problems and their generalizations.
