### Abstract:

*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.*
