Original Abstract
It is an open problem, whether matrix grammars with erasing productions using leftmost derivation of type three generate the whole family of recursively enumerable languages. This paper proves that matrix grammars that apply one matrix using leftmost derivation of type one and all other matrices using leftmost derivation of type three generate the family of recursively enumerable languages.
Keywords
Formal language theory, regulated rewriting, matrix grammar, canonical derivation, generative power.
