Abstract

In this paper we propose a Chomsky-Schützenberger type characterization of k-poly-slender context-free languages, as the homomorphical image of an intersection of a Dyck language and a (2k + 1)-poly-slender regular language. A stronger result is provided, namely the homomorphism and the Dyck language are determined irrespective of the given poly-slender context-free language, when considering the family of all poly-slender context-free languages. A similar characterization is obtained for Parikh slender context-free languages.
