—We show that every language accepted by a nondeterministic auxiliary pushdown automaton in polynomial time (that is, every language in SAC1 = Log(CFL)) can be accepted by a symm...
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...

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-...
We show that fixed membership testing for many interesting subclasses of multi-pushdown machines is no harder than for pushdowns with single stack. The models we consider are MVPA...
