Abstract
P systems (membrane systems) of various types so far mainly have been considered as computing devices working on multisets or strings. In this paper we investigate P systems with local graph productions generating weakly connected directed graphs. At least when equipped with a priority relation on the rules, such P systems can generate any recursively enumerable language of weakly connected directed graphs with only one membrane.
