Abstract. Logics of knowledge have important applications for reasoning about security protocols and multi-agent systems. We extend the semantics for the logic of necessity with lo...
One can add the machinery of relation symbols and terms to a propositional modal logic without adding quantifiers. Ordinarily this is no extension beyond the propositional. But if...
A propositional system of modal logic is second-order if it contains quantifiers p and p, which, in the standard interpretation, are construed as ranging over sets of possible worl...
We examine a logic that combines knowledge, awareness, and change of awareness. Change of awareness involves that an agent becomes aware of propositional variables. We show that th...
Abstract. We investigate the extension of modal logics by bisimulation quantifiers and present a class of modal logics which is decidable when augmented with bisimulation quanti...
