It is a well-known theorem by Chomsky and Schützenberger (1963) that every context-free language can be represented as a homomorphic image of the intersection of a Dyck language and a regular language. This paper gives a Chomsky-Schützenberger-type characterization for multiple context-free languages, which are a natural extension of context-free languages, with introducing the notion of multiple Dyck languages, which are also a generalization of Dyck languages.
