Developmental Systems with Interaction and Fragmentation

A new class of developmental systems with interaction is introduced, These systems are capable of splitting words into two or more separate parts. This property can be used to model reproduction processes and discarding parts of an organism. It is also of interest from the formal language theory point of view. This paper discusses the basic properties of the families of languages obtained, as well as their position with respect to other families of developmental languages and the families of the Chomsky hierarchy.
