Hájek 基本逻辑中的插值

Interpolation in Hájek's Basic Logic

Wesley Fussner, Simon Santschi

AI总结:

本文通过穷尽分类具有合并性质的 BL-代数簇与 basic hoop 簇,解决 Montagna 公开问题,并完整刻画 BL 及其无否定片段中具备演绎插值性质的公理化扩张。

摘要:

我们对具有 amalgamation property(合并性质)的 BL-代数簇进行了穷尽分类,证明它们仅有可数多个,并解决了 Montagna 提出的一个公开问题。作为该分类的结果,我们完整描述了 Hájek 基本模糊逻辑 BL 的哪些公理化扩张具有 deductive interpolation property(演绎插值性质)。在此过程中,我们还对具有合并性质的 basic hoop 簇,以及 BL 的无否定片段之具有演绎插值性质的公理化扩张,给出了类似分类。

英文摘要:

We exhaustively classify varieties of BL-algebras with the amalgamation property, showing that there are only countably many of them and solving an open problem of Montagna. As a consequence of this classification, we obtain a complete description of which axiomatic extensions of Hájek's basic fuzzy logic BL have the deductive interpolation property. Along the way, we provide similar classifications of varieties of basic hoops with the amalgamation property and axiomatic extensions of the negation-free fragment of BL with the deductive interpolation property.
