摘要

我们为不需要分配的（模态）格发展了对偶性，并用它来研究超越分配性的正（模态）逻辑，我们称之为弱正（模式）逻辑。这种对偶建立在满足半格的Hofmann、Mislove和Stralka对偶的基础上。我们引入了π1-持久性的概念，并证明了每一个弱正模态逻辑都是π1-持久的。这种方法为弱正模态逻辑带来了一种新的关系语义，我们证明了其类似于Sahlqvist的对应结果。1

Positive modal logic beyond distributivity

We develop a duality for (modal) lattices that need not be distributive, and use it to study positive (modal) logic beyond distributivity, which we call weak positive (modal) logic. This duality builds on the Hofmann, Mislove and Stralka duality for meet-semilattices. We introduce the notion of $Π_{1}$ -persistence and show that every weak positive modal logic is $Π_{1}$ -persistent. This approach leads to a new relational semantics for weak positive modal logic, for which we prove an analogue of Sahlqvist's correspondence result.¹

期刊介绍： The journal Annals of Pure and Applied Logic publishes high quality papers in all areas of mathematical logic as well as applications of logic in mathematics, in theoretical computer science and in other related disciplines. All submissions to the journal should be mathematically correct, well written (preferably in English)and contain relevant new results that are of significant interest to a substantial number of logicians. The journal also considers submissions that are somewhat too long to be published by other journals while being too short to form a separate memoir provided that they are of particular outstanding quality and broad interest. In addition, Annals of Pure and Applied Logic occasionally publishes special issues of selected papers from well-chosen conferences in pure and applied logic.
