非$k$-可着色图的模态逻辑可判定性

Decidability of modal logics of non-$k$-colorable graphs

Ilya Shapirovsky

AI总结:

本文研究双模态语言下非$k$-可着色图模态逻辑的可判定性,证明非$k$-可着色图(有向或无向)及其部分扩展的模态逻辑是可判定的。

摘要:

我们考虑双模态语言,其中第一个模态以标准方式由二元关系解释,第二个模态由不等关系解释。根据Hughes(1990),在此语言中,对于每个有限$k$,图的非$k$-可着色性都是可表达的。我们证明,非$k$-可着色图(有向或无向)的类的模态逻辑及其一些扩展是可判定的。

英文摘要:

We consider the bimodal language, where the first modality is interpreted by a binary relation in the standard way, and the second is interpreted by the relation of inequality. It follows from Hughes (1990), that in this language, non-$k$-colorability of a graph is expressible for every finite $k$. We show that modal logics of classes of non-$k$-colorable graphs (directed or non-directed), and some of their extensions, are decidable.
