GCM6 – Samos 1999

Karlovassi-Samos (Greece)
August 30 – September 3, 1999

The 6th International Symposium on Generalized Convexity and Monotonicity was held at the Department of Mathematics of the University of the Aegean in Karlovassi-Samos (Greece), from August 30 to September 3, 1999. About 100 participants from 22 different countries attended the conference and over sixty lectures were given.

The Symposium and its preceding Summer School were organized by the Working Group on Generalized Convexity (WGGC). Topics covered included various kinds of generalized convex functions and generalized monotone maps, optimality conditions, duality, fractional programming, multi-objective programming, nonsmooth analysis, variational inequalities, equilibrium problems as well as topics less represented at previous symposia such as stochastic convexity and global optimization. Furthermore, as at the last symposium, several invited lectures introduced participants to neighboring fields of generalized convexity. This time set-valued optimization, multiplicative/fractional programming, global optimization and stochastic programming were the emphasis with tutorials by J.Jahn (Germany), H.Konno (Japan), P.M.Pardalos (USA) and A.Prekopa (USA), respectively. The Symposium was hosted by the Department of Mathematics of the University of the Aegean, located on Samos, the birthplace of Pythagoras and Aristarchus. This truly scenic island with its interesting archeological sites gave the conference a special background.
