任意箭头更新逻辑的不可判定性

The Undecidability of Arbitrary Arrow Update Logic

Hans van Ditmarsch, Wiebe van der Hoek, Louwe B. Kuijer

摘要:

Arbitrary Arrow Update Logic是一种动态模态逻辑,它使用任意箭头更新模态来量化所有箭头更新。这种逻辑的一些性质已经被确定,但直到现在,它仍然是一个开放的问题,是否逻辑的可满足性问题是可判定的。在这里,我们证明了任意箭头更新逻辑的可满足性问题是co-RE硬的,因此不可判定的,通过减少平铺问题。

英文摘要:

Arbitrary Arrow Update Logic is a dynamic modal logic that uses an arbitrary arrow update modality to quantify over all arrow updates. Some properties of this logic have already been established, but until now it remained an open question whether the logic's satisfiability problem is decidable. Here, we show that the satisfiability problem of Arbitrary Arrow Update Logic is co-RE hard, and therefore undecidable, by a reduction of the tiling problem.
