We define and study bisimulation for proving contextual equivalence in an aspect extension of the untyped lambda-calculus. To our knowledge, this is the first study of coinductive...
We introduce G-relative-pushouts (GRPO) which are a 2-categorical generalisation of relative-pushouts (RPO). They are suitable for deriving labelled transition systems (LTS) for p...
Bisimulation between processes has been proven a successful method for formalizing security properties. We argue that in certain cases, a scheduler that has full information on the...
Abstract. We consider a formalisation of a notion of observer (or intruder) theories, commonly used in symbolic analysis of security protocols. An observer theory describes the kno...
Abstract. Bisimulation reduction is a classical means to fight the infamous state space explosion problem, which limits the applicability of automated methods for verification li...
