Projected Dynamical Systems and Evolutionary Variational Inequalities via Hilbert Spaces with Applications1

  • M. G. Cojocaru
  • P. Daniele
  • A. Nagurney


In this paper, we make explicit the connection between projected dynamical systems on Hilbert spaces and evolutionary variational inequalities. We give a novel formulation that unifies the underlying constraint sets for such inequalities, which arise in time-dependent traffic network, spatial price equilibrium, and a variety of financial equilibrium problems. We emphasize the importance of the results in applications and provide a traffic network numerical example in which we compute the curve of equilibria.
