带McKinsey公理的模态逻辑的拓扑积

Topological product of modal logics with the McKinsey axiom

Andrey Kudinov

AI总结:

本文研究带McKinsey公理的S4.1与S4模态逻辑的拓扑积,证明其等价于两逻辑融合加一条额外公理且可判定,给出了介于融合与扩张积之间的拓扑积实例。

摘要:

本文研究了S4.1与S4这两种模态逻辑的拓扑积。我们证明该拓扑积等价于S4.1与S4的逻辑融合再加上一条额外公理,同时证明了该拓扑积是可判定的。这是一个逻辑拓扑积的实例,其表达能力强于对应逻辑的融合,但弱于对应逻辑的扩张积。

英文摘要:

In this paper we consider the topological products of modal logics of S4.1 and S4. We prove that it is equal to the fusion of logics S4.1 and S4 plus one additional axiom. We also show that this product is decidable. This is an example of a topological product of logics that is greater than the fusion but less than the expanding product of the corresponding logics.
