Abstract

In this paper we study size properties of context-free returning parallel communicating grammar systems (PC grammar systems). We show that for each context-free returning PC grammar system an equivalent system of this type can be constructed, where the total number of symbols used for describing a component can be bounded by a reasonably small constant. Since context-free returning PC grammar systems determine the class of recursively enumerable languages, the result also demonstrates that the recursively enumerable language class can be economically described in terms of parallel communicating grammar systems.
