Non-well-founded trees in categories
Non-well-founded trees are used in mathematics and computer science, for modelling non-well-founded sets, as well as non-terminating processes or infinite data structures. Catego...

Presenting Functors by Operations and Equations
We take the point of view that, if transition systems are coalgebras for a functor T, then an adequate logic for these transition systems should arise from the `Stone dual' L ...

Duality for Logics of Transition Systems
We present a general framework for logics of transition systems based on Stone duality. Transition systems are modelled as coalgebras for a functor T on a category X. The propositi...

Specification-Based Testing for CoCasl's Modal Specifications
Specification-based testing is a particular case of black-box testing, which consists in deriving test cases from an analysis of a formal specification. We present in this paper an...
