Abstract. Recently, it has been shown that for any higher order pushdown system H and for any regular set C of configurations, the set pre H(C), is regular. In this paper, we give ...
Abstract. We describe a general automata-theoretic approach for analyzing the verification problems (binary reachability, safety, etc.) of discrete timed automata augmented with va...
We introduce asynchronous dynamic pushdown networks (ADPN), a new model for multithreaded programs in which pushdown systems communicate via shared memory. ADPN generalizes both CP...

To develop efficient algorithms for the reachability analysis of timed automata, a promising approach is to use binary decision diagrams (BDDs) as data structure for the representa...
We consider generalized discrete timed automata with general linear relations over clocks and parameterized constants as clock constraints and with parameterized durations. We look...
