Complexity of Safety and coSafety Fragments of Linear Temporal Logic

AAAI 2023technical

Linear Temporal Logic (LTL) is the de-facto standard temporal logic for system specification, whose foundational properties have been studied for over five decades. Safety and cosafety properties of LTL define notable fragments of LTL, where a prefix of a trace suffices to establish whether a formul…

On the First-Order Rewritability of Ontology-Mediated Queries in Linear Temporal Logic (Extended Abstract)

IJCAI 2022poster

We argue that linear temporal logic LTL in tandem with monadic first-order logic can be used as a ba- sic language for ontology-based access to tempo- ral data and obtain a classification of the resulting ontology-mediated queries according to the type of standard first-order queries they can be rew…

Living Without Beth and Craig: Definitions and Interpolants in Description Logics with Nominals and Role Inclusions

AAAI 2021technical

The Craig interpolation property (CIP) states that an interpolant for an implication exists iff it is valid. The projective Beth definability property (PBDP) states that an explicit definition exists iff a formula stating implicit definability is valid. Thus, the CIP and PBDP transform potentially h…
