We describe how the calculus of partial inductive definitions is used to represent logics. This calculus includes the powerful principle of definitional reflection. We describe two...
We describe some of the techniques which have been used to implement METATEM, a programming language based on temporal logic, and address problems such as non-determinism and loopi...
Abstract. Church's Problem (1962) asks for the construction of a procedure which, given a logical specification on sequence pairs, realizes for any input sequence X an output...
The Edinburgh Logical Framework (LF) provides a means to define (or present) logics. It is based on a general treatment of syntax, rules, and proofs by means of a typed -calculus ...
Abstract. In this paper we investigate the design space of access control logics. Specifically, we consider several possible axioms for the common operator says. Some of the axioms...
