2-Visibly Pushdown Automatality of emptiness can be recovered (preserving desirable closure properties) and solved in .. Using these properties along with the automata-theoretic approach, we prove that the model checking problem over 2-OVPA models against 2-OVPA specifications is .-complete.

On First-Order Fragments for Words and Mazurkiewicz Tracesconcerning Mazurkiewicz traces can be seen as generalizations of those for words. It turns out that over traces it is crucial, how easy concurrency can be expressed. Since there is no concurrency in words, this distinction does not occur there. In general, the possibility of expressing concurrency a

What Do We Know About Language Equations?ypes of equations whose theory has not been successfully developed already in the previous decades, and on results forming the current borderline of our knowledge. This abstract is in particular meant to provide the interested listener with references to the material discussed in the talk.

Finite Automata and the Writing of Numbersence of digits once a base is fixed, rational numbers as a pair of integer or as an ultimately periodic infinite sequence of digits, or reals as an infinite sequence of digits but also as a continued fraction, just to quote a few. Operations on numbers are defined, independently of the way they are
