We present a query language called MDatalog, which is an extension of Datalog for multimodal deductive databases. We define modal relational algebras and give the seminaive evalua...
We look at extensions of modal logic for representation and reasoning in the area of multi-agent systems. Building on dynamic logic and Henkin quantifiers, we study an unusual typ...
Abstract. We prove a conjecture by A. Pnueli and strengthen it showing a sequence of "counting modalities" none of which is expressible in the temporal logic generated by...
This paper contributes to the theory of substructural logics .that are of interest to categorial grammarians. Combining semantic ideas of Hepple [1990] and Morrill [1990], proof-t...
We present a propositional logic to reason about the uncertainty of events, where the uncertainty is modeled by a set of probability measures assigning an interval of probability ...
