经典模态逻辑格的自同构

Automorphisms of the Lattice of Classical Modal Logics

Adrian Soncodi

摘要:

本文分析了最小经典模态逻辑系统E的命题扩张,它们构成一个格CExtE。我们的分析方法使用代数计算与规范形式,这是一个推广的规范形式适用于正常的模态逻辑。作为应用,我们确定了CExtE的一个自同构群,它同构于对称群S4。

英文摘要:

In this paper we analyze the propositional extensions of the minimal classical modal logic system E, which form a lattice denoted as CExtE. Our method of analysis uses algebraic calculations with canonical forms, which are a generalization of the normal forms applicable to normal modal logics. As an application, we identify a group of automorphisms of CExtE that is isomorphic to the symmetric group S4.
