Coalgebraic trace semantics via forgetful logics

Bartek Klin ; Jurriaan Rot.

We use modal logic as a framework for coalgebraic trace semantics, and show the flexibility of the approach with concrete examples such as the language semantics of weighted, alternating and tree automata, and the trace semantics of generative probabilistic systems. We provide a sufficient condition&nbsp;[&hellip;]

On Tools for Completeness of Kleene Algebra with Hypotheses

Damien Pous ; Jurriaan Rot ; Jana Wagemaker.

In the literature on Kleene algebra, a number of variants have been proposed which impose additional structure specified by a theory, such as Kleene algebra with tests (KAT) and the recent Kleene algebra with observations (KAO), or make specific assumptions about certain constants, as for instance&nbsp;[&hellip;]
