We study generalised polynomial functors between presheaf categories, developing their mathematical theory together with computational applications. The main theoretical contribution is the introduction of discrete generalised polynomial functors, a class that lies in between the classes of cocontinuous and finitary functors, and is closed under composition, sums, finite products, and differentiation. A variety of applications are given: to the theory of nominal algebraic effects; to the algebraic modelling of languages, and equational theories there of, with variable binding and polymorphism; and to the synthesis of dependent zippers. © 2012 Springer-Verlag Berlin Heidelberg.
