Abstract. The Galois Sub-hierarchy (GSH) is a polynomial-size representation of a concept lattice which has been applied to several fields, such as software engineering and linguis...
Abstract. This paper provides an overview of an approach to coalgebraic modelling and refinement of state-based software components, summing up some basic results and introducing a...
Recent years have seen a proliferation of 3-valued or capturing abstractions of systems, since these enable verifying both universal and existential properties. Reasoning about suc...
Abstract-- This paper describes a symbolic algorithm for overapproximating reachability in Boolean programs with unbounded thread creation. The fix-point is detected by projecting ...
In this paper we shall survey and discuss in detail the work on the relative expressiveness of recursion and replication in various process calculi. Namely, CCS, the -calculus, the...
