Recently visibly pushdown automata have been extended to so called k-phase multistack visibly pushdown automata (k-MVPAs). On the occasion of introducing kMVPAs, it has been asked...
We introduce discrete pushdown timed automata that are timed automata with integer-valued clocks augmented with a pushdown stack. A con guration of a discrete pushdown timed automa...

We present uniform approaches to establish complexity bounds for decision problems such as reachability and simulation, that arise naturally in the verification of timed software s...

Abstract. Deterministic graph grammars are finite devices which generate the transition graphs of pushdown automata. We define the notion of synchronization by grammars, generalizi...
Abstract. Regular Model-Checking (RMC) is a technique for the formal verification of infinite state systems based on the theory of regular languages. In the paper “Beyond Regul...
