Abstract
The paper introduces the concept of cut-and-paste polynomial function, which models operations on words inspired from contextual languages and DNA computing. Fixed-point equations attached to such functions become generative devices for new classes of languages. The class of first-degree 2CP-languages is shown to be incomparable with the Chomsky hierarchy. We give some examples which motivate further study of higher degree CP-languages.
