| Abstract: | We construct a Hilbert style system RPL for the notion of plausibility measure introduced by Halpern J, and we prove the soundness and completeness with respect to a neighborhood style semantics. Using the language of RPL, we demonstrate that it can define well-studied notions of necessity, conditionals and propositional identity. The paper is partially supported by a project (No. 05JJD720. 40001) granted by the Key Research Institutes for Humanities and Social Sciences of Chinese Ministry of Education. |
