Center node: "model checking synchronized products of infinite transition systems"
  Abstract: Formal verification using the model checking paradigm has to deal with two#N#aspects: The system models are structured, often as products of components, and#N#the specification logic has to be expressive enough to allow the formalization#N#of reachability properties. The present paper is a study on what can be#N#achieved for infinite transition systems under these premises. As models we#N#consider products of infinite transition systems with different synchronization#N#constraints. We introduce finitely synchronized transition systems, i.e.#N#product systems which contain only finitely many (parameterized) synchronized#N#transitions, and show that the decidability of FO(R), first-order logic#N#extended by reachability predicates, of the product system can be reduced to#N#the decidability of FO(R) of the components. This result is optimal in the#N#following sense: (1) If we allow semifinite synchronization, i.e. just in one#N#component infinitely many transitions are synchronized, the FO(R)-theory of the#N#product system is in general undecidable. (2) We cannot extend the expressive#N#power of the logic under consideration. Already a weak extension of first-order#N#logic with transitive closure, where we restrict the transitive closure#N#operators to arity one and nesting depth two, is undecidable for an#N#asynchronous (and hence finitely synchronized) product, namely for the infinite#N#grid.
