关于Halpern-Shoham区间时态逻辑的最后一篇论文

The Last Paper on the Halpern-Shoham Interval Temporal Logic

Jerzy Marcinkowski, Jakub Michaliszyn

摘要:

Halpern-Shoham逻辑是时间间隔的模态逻辑。在过去的十年里,人们已经做出了一些努力,根据可满足性问题的可判定性对这个美丽逻辑的片段进行分类。我们有助于这一努力显示-我们认为是一个相当意外的结果-的逻辑的子区间,片段的Halpern-Shoham,其中只有运营商“期间”,或D,是允许的,是不可判定的离散结构。这是令人惊讶的,因为这个逻辑是可判定的密集秩序和其自反的变种是已知的可判定的离散结构。

英文摘要:

The Halpern-Shoham logic is a modal logic of time intervals. Some effort has been put in last ten years to classify fragments of this beautiful logic with respect to decidability of its satisfiability problem. We contribute to this effort by showing - what we believe is quite an unexpected result - that the logic of subintervals, the fragment of the Halpern-Shoham where only the operator "during", or D, is allowed, is undecidable over discrete structures. This is surprising as this logic is decidable over dense orders and its reflexive variant is known to be decidable over discrete structures.
