Quantitative bisimulations using coreflections and open morphisms [article]

Jérémy Dubut, Ichiro Hasuo, Shin-ya Katsumata, David Sprunger
2018 arXiv   pre-print
We use the fact, from Joyal et al., that coreflections preserve open morphisms situations in the sense that a coreflection induces a path subcategory in the category of systems in such a way that open  ...  We prove that this method is particularly well-suited for systems with quantitative information: we canonically recover the path category of probabilistic systems from Cheng et al., and of timed systems  ...  Quantitative bisimulations using coreflections and open morphisms A Omitted proofs from Section 2.4 Proof (of Proposition 3). iii) ⇒ i) Obvious. i) ⇒ ii) Given such a span f : T ′′ −→ T and g : T  ...

Endofunctors modelling higher-order behaviours [article]

Marco Peressotti
2016 arXiv   pre-print
in the former higher-order is expressed by passing around syntactic objects (such as terms or processes) as representations of behaviours whereas the former ditches the syntactic encoding altogether and  ...  As a direct application of the theory of coalgebras, we are now able to define a canonical higher-order coalgebraic bisimulation and show it to coincide with coalgebraic bisimulation for value-passing  ...  In particular, we expect to be able to define general higher-order trace equivalences and higher-order weak bisimulations by applying the constructions given in [6, 7, 17, 26] .  ...

Behavioural equivalences for timed systems [article]

Tomasz Brengos, Marco Peressotti
2019 arXiv   pre-print
Timed transition systems are behavioural models that include an explicit treatment of time flow and are used to formalise the semantics of several foundational process calculi and automata.  ...  We instantiate our framework to timed transition systems and their quantitative extensions such as timed probabilistic systems.  ...  Their approach is based on open-maps bisimulation and is limited to non-deterministic timed transition systems.  ...
