Bisimilarity of One-Counter Processes Is PSPACE-Complete
A one-counter automaton is a pushdown automaton over a singleton stack alphabet. We prove that the bisimilarity of processes generated by nondeterministic one-counter automata (wit...

Synchronization of Pushdown Automata
Abstract. We introduce the synchronization of a pushdown automaton by a sequential transducer associating an integer to each input word. The visibly pushdown automata are the autom...

A Context-Free Process as a Pushdown Automaton
A well-known theorem in automata theory states that every context-free language is accepted by a pushdown automaton. We investigate this theorem in the setting of processes, using ...

Model Checking CTL Properties of Pushdown Systems
: A pushdown system is a graph G(P) of configurations of a pushdown automaton P. The model checking problem for a logic L is: given a pushdown automaton P and a formula L decide ...

Pushdown Games with Unboundedness and Regular Conditions
We consider infinitary two-player perfect information games defined over graphs of configurations of a pushdown automaton. We show how to solve such games when winning condition...

Regular Sets of Higher-Order Pushdown Stacks
Abstract. It is a well-known result that the set of reachable stack contents in a pushdown automaton is a regular set of words. We consider the more general case of higher-order pu...

Incremental Validation of String-Based XML Data in Databases, File Systems, and Streams
Although the native (tree-like) storage of XML data becomes more and more important there will be an enduring demand to manage XML data in its textual representation, for instance ...

Event-Clock Visibly Pushdown Automata
Abstract. We introduce the class of event-clock visibly pushdown automata (ECVPAs) as an extension of event-clock automata. The class of ECVPAs, on one hand, can model simple real-...
