摘要:
Perfect equilibrium and its refinements are widely studied and typically rely on full-support perturbations. We introduce a delta-localized notion of perfection for games with a continuum of players. It confines perturbations within a delta-neighborhood of the underlying action distribution and eliminates undesirable equilibria from a local perspective. We establish the existence of a pure strategy delta-localized perfect equilibrium and show that it is equivalent to delta-admissible Nash equilibrium. We also study limit versions of delta-localized perfection. Illustrative applications to large routing games and crowd saturation games are presented.
