In this paper we use a duality result between equations and coequations for automata, proved by Ballester-Bolinches, Cosme-Ll´opez, and Rutten to characterize nonempty classes of ...
Rely-Guarantee reasoning is a well-known method for verification of shared-variable concurrent programs. However, it is difficult for users to define rely/guarantee conditions, ...
The correspondence between up-closed multirelations and isotone predicate transformers is well known. Less known is that multirelations have also been used for modelling topologica...
Abstract. Bidirectional transformations (bx) support principled consistency maintenance among data sources. Each data source corresponds to one perspective on a composite system, m...
