Abstract

This paper discusses new kind of a restriction placed on tree-controlled grammars-context-free grammars with some root-to-leaf paths in their derivation trees restricted by a control language. We introduce an n-path restriction and demonstrate that if the control language is linear, there are several families of generated languages depending on the length of common part of restricted paths. Then, the paper introduces several pumping properties of these families.
