Contextual array P systems
TLDR
The relation between external arrays contextual P systems and external array contextual grammars with regular control is obtained and some properties of these systems are discussed.Abstract:
We define external and internal array contextual P systems, which generate rectangular arrays. We also introduce external array contextual P systems with erased contexts. Some properties of these systems are discussed. We obtain the relation between external array contextual P systems and external array contextual grammars with regular control.read more

Computing with Membranes
TL;DR: It is proved that the P systems with the possibility of objects to cooperate characterize the recursively enumerable sets of natural numbers; moreover, systems with only two membranes suffice.

Picture languages with array rewriting rules
TL;DR: Generative models of picture languages with array rewriting rules are presented and each letter of the alphabet of different sizes can be generated by a context-free array grammar.
