Abstract

The paper formally describes an operational semantics of P systems. We present an abstract syntax of P systems, then the notion of configurations, and we define the sets of inference rules corresponding to the three stages of an evolution step: maximal parallel rewriting, parallel communication, and parallel dissolving. Several results assuring the correctness of each set of inference rules are also presented. Finally, we define simulation and bisimulation relations between P systems.
