The paper proposes a formal analysis of the ascriptive view of norms as resulting from pulling together Anderson's reductionist approach, the analysis of counts-as, and a nove...
There has been a great deal of work on characterizing the complexity of the satisfiability and validity problem for modal logics. In particular, Ladner showed that the consistency...
In this paper, we focus our attention on the fragment of Halpern and Shoham's modal logic of intervals (HS) that features four modal operators corresponding to the relations &...
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...
