Characteristic Logics for Behavioural Hemimetrics via Fuzzy Lax Extensions

Paul Wild ; Lutz Schröder.

In systems involving quantitative data, such as probabilistic, fuzzy, or metric systems, behavioural distances provide a more fine-grained comparison of states than two-valued notions of behavioural equivalence or behaviour inclusion. Like in the two-valued case, the wide variation found in system&nbsp;[&hellip;]

Quasilinear-time Computation of Generic Modal Witnesses for Behavioural Inequivalence

Thorsten Wißmann ; Stefan Milius ; Lutz Schröder.

We provide a generic algorithm for constructing formulae that distinguish behaviourally inequivalent states in systems of various transition types such as nondeterministic, probabilistic or weighted; genericity over the transition type is achieved by working with coalgebras for a set functor in the&nbsp;[&hellip;]
