Vector Variational Inequalities and Vector Equilibria O.P Abstract: «Der Mensch warIn the fifties and sixties, several real problems, old and new, especially in Physics, Mechanics, Fluidodynamics, Structural Engi neering, have shown the need of new mathematical models for study ing the equilibrium of a system. This has led to the formulation of Variational Inequalities (by G. Stampacchia), and to the develop ment of Complementarity Systems (by W. S. Dorn, G. B. Dantzig, R. W. Cottle, O. L. Mangasarian et al.) with important
