Alternating timed automata on infinite words are considered. The main result is a characterization of acceptance conditions for which the emptiness problem for the automata is deci...
We show that the family of tree languages recognized by weak alternating automata is closed by three set theoretic operations that correspond to sum, multiplication by ordinals <...
Model checking is a method for the verification of systems with respect to their specifications. Symbolic model-checking, which enables the verification of large systems, procee...
