模糊逻辑的Kripke语义

Kripke Semantics for Fuzzy Logics

Parvin Safari, Saeed Salehi

摘要:

克里普克框架(和模型)为次经典逻辑提供了合适的语义,例如直觉主义逻辑(布劳威尔和海廷)将自反和传递克里普克框架(具有持久满意关系)公理化,而基本逻辑(维瑟)将传递克里普克框架(具有持久满意关系)公理化。在这里,我们调查Kripke框架/模型是否可以提供一个语义模糊逻辑。对于基本模糊逻辑的每一个公理,寻找满足它们的Kripke框架/模型的充要条件。事实证明,唯一的模糊逻辑(包含基本模糊逻辑的逻辑),这是健全的和完整的关于一类克里普克框架/模型是哥德尔逻辑(或超直觉主义逻辑的达米特)的扩展,事实上,这种逻辑是健全的和强完整的关于自反,传递和连接(线性)克里普克框架(与持久的满意关系)。这为(命题)模糊逻辑中的哥德尔逻辑提供了一个语义特征。

英文摘要:

Kripke frames (and models) provide a suitable semantics for sub-classical logics, for example Intuitionistic Logic (of Brouwer and Heyting) axiomatizes the reflexive and transitive Kripke frames (with persistent satisfaction relations), and the Basic Logic (of Visser) axiomatizes transitive Kripke frames (with persistent satisfaction relations). Here, we investigate whether Kripke frames/models could provide a semantics for fuzzy logics. For each axiom of the Basic Fuzzy Logic, necessary and sufficient conditions are sought for Kripke frames/models which satisfy them. It turns out that the only fuzzy logics (logics containing the Basic Fuzzy Logic) which are sound and complete with respect to a class of Kripke frames/models are the extensions of the Gödel Logic (or the super-intuitionistic logic of Dummett), indeed this logic is sound and strongly complete with respect to reflexive, transitive and connected (linear) Kripke frames (with persistent satisfaction relations). This provides a semantic characterization for the Gödel Logic among (propositional) fuzzy logics.
