余归纳谓词的表现性逻辑

Expressive Logics for Coinductive Predicates

Clemens Kupke, Jurriaan Rot

AI总结:

本文在余代数一般框架下研究逻辑对余归纳谓词的完全表征,提出充分性与表现性条件,并应用于相似性、发散性及自动机行为度量等实例。

摘要:

经典的 Hennessy-Milner 定理指出,在图像有限迁移系统中,两个状态互模拟当且仅当它们在某种模态逻辑中满足相同的公式。本文在一般化背景下研究此类结果,将研究对象从迁移系统扩展到余代数,并将互模拟关系推广至余归纳谓词。我们通过提出适当的充分性与表现性概念,刻画了逻辑完全表征余代数上余归纳谓词的条件,并给出了语义上的充分条件。该方法通过表征相似性、发散性以及自动机上的行为度量的逻辑加以说明。

英文摘要:

The classical Hennessy-Milner theorem says that two states of an image-finite transition system are bisimilar if and only if they satisfy the same formulas in a certain modal logic. In this paper we study this type of result in a general context, moving from transition systems to coalgebras and from bisimilarity to coinductive predicates. We formulate when a logic fully characterises a coinductive predicate on coalgebras, by providing suitable notions of adequacy and expressivity, and give sufficient conditions on the semantics. The approach is illustrated with logics characterising similarity, divergence and a behavioural metric on automata.
