We use the framework of biorthogonality to introduce a novel semantic definition of the concept of barb (basic observable) for process calculi. We develop a uniform basic theory o...
Reactive systems, proposed by Leifer and Milner, represent a meta-framework aimed at deriving behavioral congruences for those specification formalisms whose operational semantics...
We study the behavioural theory of Cardelli and Gordon’s Mobile Ambients. We give an lts based operational semantics, and a labelled bisimulation based equivalence that coincide...
We develop a theory of bisimulations in the join-calculus. We introduce a refined operational model that makes interactions with the environment explicit, and discuss the impact o...
We define logical relations between the denotational semantics of a simply typed functional language with recursion and the operational behaviour of low-level programs in a varian...
