组合逻辑的模块化多值语义

Modular many-valued semantics for combined logics

Carlos Caleiro, Sérgio Marcelino

AI总结:

本文利用部分非确定性矩阵上的通用运算,为组合逻辑构建可直接复用各成分逻辑多值语义的模块化语义,并分析有限值性、公理化、片段演算组合与可判定性保持条件。

摘要:

我们首次获得了组合逻辑的模块化多值语义,该语义通过对部分非确定性逻辑矩阵施加适当的通用运算,直接由被组合逻辑的多值语义构建而成。在多结论逻辑的语境下,我们的构造保持有限值性;而不出所料,在单结论逻辑的语境下,有限值性可能会丧失。除了通过大量示例说明我们的构造之外,我们还对这些语义刻画发展了具体应用,即涉及以下方面:用附加公理强化给定多值逻辑的语义;研究在何种条件下,给定逻辑可被视为由更简单的、句法定的片段组合而成,而这些片段的演算可以独立获得并组合起来,形成整个逻辑的演算;以及组合机制保持可判定性的一般条件。

英文摘要:

We obtain, for the first time, a modular many-valued semantics for combined logics, which is built directly from many-valued semantics for the logics being combined, by means of suitable universal operations over partial non-deterministic logical matrices. Our constructions preserve finite-valuedness in the context of multiple-conclusion logics whereas, unsurprisingly, it may be lost in the context of single-conclusion logics. Besides illustrating our constructions over a wide range of examples, we also develop concrete applications of our semantic characterizations, namely regarding the semantics of strengthening a given many-valued logic with additional axioms, the study of conditions under which a given logic may be seen as a combination of simpler syntactically defined fragments whose calculi can be obtained independently and put together to form a calculus for the whole logic, and also general conditions for decidability to be preserved by the combination mechanism.
