An array is a two-dimensional generalization of a string. Both sides of each rewriting rule of an isotonic array grammar have the same shape. In this paper we complete the Chomsky hierarchy of isotonic array grammars by introducing isotonic context-free array grammars. We obtain Chomsky and Greibach
This paper proves the existence of a hierarchy of languages which is properly contained in the context sensitive languages and which starts with the context-free family. The hierarchy is defined inductively by controlling labeled linear grammars with languages in one family to yield languages in the
