We address the task of deriving fixpoint equations from modal logics characterizing
behavioural equivalences and metrics (summarized under the term conformances). We rely on …

We introduce a general and compositional, yet simple, framework that allows us to derive
soundness and expressiveness results for modal logics characterizing behavioural …

In order to provide a rigorous foundation for Software Product Lines (SPLs), several fundamental
approaches have been proposed to their formal behavioral modeling. In this paper, we …

This thesis addresses two particular issues related to the design of embedded systems; namely,
refinement of communication and refinement of states. The refinement of communication …

We introduce a variant of transition systems, where activation of transitions depends on
conditions of the environment and upgrades during runtime potentially create additional …

The framework of graded semantics uses graded monads to capture behavioural equivalences
of varying granularity, for example as found in the linear-time / branching-time spectrum, …

We extend the theory of input–output conformance (IOCO) testing to accommodate behavioral
models of software product lines (SPLs). We present the notions of residual and spinal …

The task of implementing supervisory controllers is non-trivial, even though there are different
theories that allow automatic synthesis of such controllers in the form of automata. One of …

The task of implementing a supervisory controller is non-trivial, even though different theories
exist that allow automatic synthesis of these controllers in the form of automata. One of the …

It is well known that the theory of coalgebras provides an abstract definition of behavioural
equivalence that coincides with strong bisimulation across a wide variety of state-based …
