We develop duality between nuclei on Heyting algebras and certain binary relations on Heyting spaces. We show that these binary relations are in 1–1 correspondence with subframe...
Modern hardware designs are typically based on multiple clocks. While a singly-clocked hardware design is easily described in standard temporal logics, describing a multiply-clocke...
Two things are done in this paper. First, a modal logic in which one can quantify over both objects and concepts is presented; a semantics and a tableau system are given. It is a n...
Abstract. We consider a simple model of higher order, functional computations over the booleans. Then, we enrich the model in order to encompass non-termination and unrecoverable e...
We explain the raison d’ˆetre and basic ideas of input/output logic, sketching the central elements with pointers to other publications for detailed developments. The motivation...
