C.: Time-dependent equilibrium problems

Abstract The paper presents variational models for dynamic traffic, dynamic mar-ket, and evolutionary financial equilibrium problems taking into account that the equilibria are not fixed and move with time. The authors provide a review of the his-tory of the variational inequality approach to problems in physics, traffic networks, and others, then they model the dynamic equilibrium problems as time-dependent variational inequalities and give existence results. Moreover, they present an infinite dimensional Lagrangean duality and apply this theory to the above time-dependent variational inequalities. Key words: time-dependent variational inequalities, dynamic traffic, dy-namic market and evolutionary financial equilibrium problems, Lagrangean duality.
