An Example for Concurrent Re ective Computations in Rewriting Logic

Rewriting logic can represent dynamic behaviors of concurrent and/or reactive systems declaratively. Declarative descriptions in rewriting logic are expected to be amenable to analysis of interesting properties. The group-wide architecture based on the actor model is a speci c concurrent re ective computation model based on "group-wide re ection". It has a potential of modeling cooperative behaviors of several software modules (or agents). This paper provides some basic considerations on methods of modeling the group-wide architecture in rewriting logic and a brief proof that the metalevel group of terms correctly represents the operational semantics of the group in terms of transitions of con gurations.
