拓扑语义与可判定性

Topological Semantics and Decidability

Dmitry Sustretov

摘要:

众所周知,所有拓扑空间的基本模态逻辑是$S4$。然而,满足各种分离公理的空间类的基本模态和混合逻辑的结构直到现在还不清楚。本文证明了$T_0$、$T_1$和$T_2$拓扑空间的模态逻辑是重合的,并且是S4 $. We also examine basic hybrid logics of these classes and prove their decidability; as part of this, we find out that the hybrid logics of $ T_1 $ and T_2$空间重合的.

英文摘要:

It is well-known that the basic modal logic of all topological spaces is $S4$. However, the structure of basic modal and hybrid logics of classes of spaces satisfying various separation axioms was until present unclear. We prove that modal logics of $T_0$, $T_1$ and $T_2$ topological spaces coincide and are S4$. We also examine basic hybrid logics of these classes and prove their decidability; as part of this, we find out that the hybrid logics of $T_1$ and T_2$ spaces coincide.
