P systems with active membranes were used to generate languages, in the sense
of languages associated with the structure of membrane systems. Here, we
analyze the power of P systems with membrane creation and dissolution
restricted to elementary membranes, P systems without membrane dissolution
operating according to certain output modes. This leads us to characterizations
of recursively enumerable languages.Comment: Presented at MeCBIC 201
