Tense distributive lattices: algebra, logic and topology

Aldo Victorio Figallo, Jonathan Sarmiento, Martín Figallo

AI总结:

本文研究了配备Prior时态算子的有界分配格范畴tdlat,建立了其与Kripke框架和Priestley空间的范畴对偶性,刻画了同余格与次直不可约成员,并定义了保持真值度的逻辑。

摘要:

时态逻辑由Arthur Prior在20世纪50年代末提出,源于他对时态与模态之间关系的兴趣。Prior的想法是在基础语言中加入四个原始的类模态一元连接词,如今这被广泛称为Prior时态算子。此后,Prior算子被不同作者在多种语境下考虑,特别是在代数逻辑的语境中。本文考虑配备了Prior时态算子的有界分配格的范畴tdlat。我们分别用Kripke框架和Priestley空间的特定范畴建立了tdlat的范畴对偶性。作为应用,我们刻画了任意时态分配格的同余格以及该范畴的次直不可约成员。最后,我们定义了保持关于tdlat-代数的真值度的逻辑,并精确了tdlat的特定子类与文献中已知时态逻辑之间的关系。

英文摘要:

Tense logic was introduced by Arthur Prior in the late 1950s as a result of his interest in the relationship between tense and modality. Prior's idea was to add four primitive modal-like unary connectives to the base language today widely known as Prior's tense operators. Since then, Prior's operators have been considered in many contexts by different authors, in particular, in the context of algebraic logic. Here, we consider the category tdlat of bounded distributive lattices equipped with Prior's tense operators. We establish categorical dualities for tdlat in terms of certain categories of Kripke frames and Priestley spaces, respectively. As an application, we characterize the congruence lattice of any tense distributive lattice as well as the subdirectly irreducible members of this category. Finally, we define the logic that preserves degrees of truth with respect to tdlat-algebras and precise the relation between particular sub-classes of tdlat and know tense logics found in the literature.
