Generalized Convexity: Proceedings of the IVth International Workshop on Generalized Convexity Held at Janus Pannonius University P?cs, Hungary, Augus [Paperback]

Generalizations of the classical concept of a convexfunction have been proposed in various fields such aseconomics, management science, engineering, statistics andapplied sciences during the second half of this century. Inaddition to new results in more established areas ofgeneralized convexity, this book presents several importantdevelopments in recently emerging areas. Also, a number ofinteresting applications are reported.I. Generalized convex functions.- Univex sets, functions and univex nonlinear programming.- Optimization on closely convex sets.- A note on ordinal concavity.- Generalized concavity in cooperative game theory: characterizations in terms of the core.- On the existence of Nash-equilibrium in n-person generalized concave games.- A deep cut ellipsoid algorithm and quasiconvex programming.- Quasiconvexity and related properties in the calculus of variations.- Ray-quasiconvex and f-quasiconvex functions.- Geodesic convexity on ?n.- A class of differentiable generalized convex functions.- Equivalence between generalized gradients and subdifferentials (lower semigradients) for a suitable class of lower semicontinuous functions.- II. Optimality and duality.- Generalizing convexity for second order optimality conditions.- Regularity conditions for constrained extremum problems via image space approach: the linear case.- Duality theory for convex/quasiconvex functions and its application to optimization.- First order generalized optimality conditions for programming problems with a set constraint.- Abstract nonsmooth nonconvex programming.- A survey on optimality and duality in nonsmooth programming.- III. Generalized monotone maps.- Generalized monotonicity  a survey.- Orderings, generalized convexity and monotonicity.- Generalized monotonicity in non-smooth analysis.- Some invariance properties of generalized monotonicity.- IV.
