Concrete domains in logics

Abstract

In this short survey, we present logical formalisms in which reasoning about concrete domains is embedded in formulae at the atomic level. These include temporal logics with concrete domains, description logics with concrete domains as well as variant formalisms. We discuss several proof techniques to solve logical decision problems for such formalisms, including those based on constrained automata or on translation into decidable second-order logics. We also present recent results mainly related to decidability and complexity as well as a selection of open problems.
