策略集扰动下Nash平衡的精炼

The Refinements of Nash Equilibrium under the Perturbation of Strategy Sets

通过定义一种策略集的扰动映射,引入一种新的稳定Nash平衡的概念,并利用Ky Fan不等式定理的相关结果证明该稳定Nash平衡的存在性.

To define a perturbation mapping of strategy sets and give a new concept about the stable Nash equilibrium,the existence of it by an outcome of the Ky Fan inequality is studied.
