De Francesco N., Fantechi A., Gnesi S., Inverardi P. Model checking of non-finite state processes by finite approximations. Internal note IEI-B4-54, 1993.
In this paper we present a verification methodology, using an action-based logic, able to check properties for full CCS terms, allowing also verification on infinite state systems, Obviously, for some properties we are only able to give a semidecision procedure. The idea is to use a sequence of) finite state transition systems which approximate the, possibly infinite state, transition system corresponding to a term. To this end we define a particular notion of approximation, which is stronger than simulation, suitable to define and prove liveness and safety properties of the process terms.
