Predicate and relation liftings for coalgebras with side effects: an application in coalgebraic modal logic
H. Beohar, B. König, S. Küpper +1
We study coalgebraic modal logic to characterise behavioural equivalence in the presence of side effects, i.e., when coalgebras live in a (co)Kleisli or an Eilenberg-Moore category…

Explaining Non-Bisimilarity in a Coalgebraic Approach: Games and Distinguishing Formulas
Barbara König, Christina Mika-Michalski, Lutz Schröder
Behavioural equivalences can be characterized via bisimulation, modal logics, and spoiler-duplicator games. In this paper we work in the general setting of coalgebra and focus on g…

Fixpoint Games on Continuous Lattices
Paolo Baldan, Barbara König, Tommaso Padoan +1
Many analysis and verifications tasks, such as static program analyses and model-checking for temporal logics reduce to the solution of systems of equations over suitable lattices.…
