秩1模态逻辑的PSPACE界

PSPACE Bounds for Rank-1 Modal Logics

Lutz Schröder, Dirk Pattinson

摘要:

由于缺乏适用于各种逻辑的通用算法方法,为给定的模态逻辑建立复杂性界限通常是一项艰巨的任务。目前的工作是一个一般理论的复杂性模态逻辑的一步。我们的主要结果是,所有秩1逻辑享有浅模型属性,因此,在温和的假设下,其axiomatisation格式,在PSPACE。这导致了一个统一的推导紧PSPACE边界的一些逻辑,包括K,KD,联盟逻辑,分级模态逻辑,多数逻辑和概率模态逻辑。此外,我们的通用算法发现,见证愉快的证明理论的性质,包括一个弱子公式属性的Tableau证明。这种普遍性是由一个coalgebraic语义,方便地抽象的细节,一个给定的模型类,从而允许覆盖范围广泛的逻辑在一个统一的方式。

英文摘要:

For lack of general algorithmic methods that apply to wide classes of logics, establishing a complexity bound for a given modal logic is often a laborious task. The present work is a step towards a general theory of the complexity of modal logics. Our main result is that all rank-1 logics enjoy a shallow model property and thus are, under mild assumptions on the format of their axiomatisation, in PSPACE. This leads to a unified derivation of tight PSPACE-bounds for a number of logics including K, KD, coalition logic, graded modal logic, majority logic, and probabilistic modal logic. Our generic algorithm moreover finds tableau proofs that witness pleasant proof-theoretic properties including a weak subformula property. This generality is made possible by a coalgebraic semantics, which conveniently abstracts from the details of a given model class and thus allows covering a broad range of logics in a uniform way.
