We show that the locally free class group of an order in a semisimple algebra over a number field is isomorphic to a certain ray class group. This description is then used to prese...
Abstract Cloud computing could offer good business models for small CSE (Computational Science and Engineering) research groups because these groups often do not have enough human ...
This paper reports on and discusses three notions of approximation for Labelled Markov Processes that have been developed last year. The three schemes are improvements over former...
We present novel techniques for efficient controller synthesis for untimed and timed systems with respect to invariance and reachability properties. In the untimed case, we give al...
