Approximate Solutions and Tikhonov Well-Posedness for Nash Equilibria

  • L. Pusillo Chicco
Part of the Nonconvex Optimization and Its Applications book series (NOIA, volume 58)


This contribution is in the framework of non-cooperative games with focus on the main solution concept: the Nash equilibrium (NE). The properties of Tikhonov well-posedness for Nash equilibria (briefly T-wp for NE) will be analized with a particular attention to its generalization: Tikhonov well-posedness in value (T w -wp) which is an ordinal property. Metric characterizations of T w -wp will be discussed and known results, which give existence and uniqueness of NE in oligopoly model, will be proved to guarantee T-wp too.
