Abstract
We introduce Concurrent Timed Automata (CTAs) where automata running in parallel are synchronized. We consider the subclasses of CTAs obtained by admitting, or not, diagonal clock constraints and constant updates, and by letting, or not, sequential automata to update the same clocks. We prove that such subclasses recognize the same languages but differ from the point of view of succinctness.
