中间逻辑中强等价逻辑程序的刻画

Characterization of Strongly Equivalent Logic Programs in Intermediate Logics

Dick de Jongh, Lex Hendriks

摘要:

与逻辑程序的答案集语义相关的非经典、非单调推理关系产生了逻辑程序之间的“强等价”关系,该关系可以在3值Goedel逻辑G3中得到验证,G3是最强的非经典中间命题逻辑(Lifschitz,Pearce和Valverde,2001)。本文将证明KC(通过将公理~A v ~A加到直觉逻辑中而得到的逻辑)是最弱的中间逻辑,对于它,强等价的逻辑程序在允许否定的语言中是逻辑等价的。

英文摘要:

The non-classical, nonmonotonic inference relation associated with the answer set semantics for logic programs gives rise to a relationship of 'strong equivalence' between logical programs that can be verified in 3-valued Goedel logic, G3, the strongest non-classical intermediate propositional logic (Lifschitz, Pearce and Valverde, 2001). In this paper we will show that KC (the logic obtained by adding axiom ~A v ~~A to intuitionistic logic), is the weakest intermediate logic for which strongly equivalent logic programs, in a language allowing negations, are logically equivalent.
