交互式无意识再探
Interactive Unawareness Revisited
摘要：
我们分析了海菲兹，迈耶和席佩尔（HMS）介绍的互动无意识模型。我们考虑两个公理化的模型，捕捉不同的概念的有效性。这些公理化使我们能够比较HMS方法的标准（S5）认知逻辑和其他两种方法的无意识：费金和Halpern和莫迪卡和Rustichini。我们发现，HMS方法和其他之间的差异主要是由于使用的有效性的概念和事实，即HMS是基于一个3值命题逻辑。
英文摘要：
We analyze a model of interactive unawareness introduced by Heifetz, Meier and Schipper (HMS). We consider two axiomatizations for their model, which capture different notions of validity. These axiomatizations allow us to compare the HMS approach to both the standard (S5) epistemic logic and two other approaches to unawareness: that of Fagin and Halpern and that of Modica and Rustichini. We show that the differences between the HMS approach and the others are mainly due to the notion of validity used and the fact that the HMS is based on a 3-valued propositional logic.
