The method of logical relations is a classic technique for proving the equivalence of higher-order programs that implement the same observable behavior but employ different intern...

We propose a modular approach to defining notions of simulation, and modal logics which characterise them. We use coalgebras to model state-based systems, relators to define notio...

Abstract. leanK is a "lean", i.e., extremely compact, Prolog implementation of a free variable tableau calculus for propositional modal logics. leanK 2.0 includes additio...

Hybrid logics are a principled generalization of both modal logics and description logics, a standard formalism for knowledge representation. In this paper we give the first const...
