N. S. Kukushkin Economics Letters , V.64 , 01.1999 , p. 279-283, language: английский  Аннотация As a slight revision of Monderer and Shapley's definition, a potential for a strategic game is defined as a strict order on the set of strategy profiles, containing effective preferences of all players. The agent normal form of a finite game with perfect information is shown to have a potential. A topological restriction on the potential for an infinite game is suggested, guaranteeing the existence of a Nash equilibrium when the set of strategy profiles is compact.  Ключевые слова Potential games, Monderer definition, Shapley definition, strategy profile, existence of a Nash equilibrium
