摘要

A general condition called coarser traits is introduced and shown to be necessary and sufficient for the idealized limit property of large games with traits. Moreover, we illustrate the minimality of the coarser traits condition by showing its necessity in deriving the existence of pure-strategy Nash equilibria in large games with traits.
