Abstract
Given a closed set of measure zero and a continuous function , the classical Rudin-Carleson interpolation theorem states that there exists a continuous function that is holomorphic on and satisfies . In this paper we obtain a generalisation of the Rudin-Carleson theorem for maps into arbitrary connected complex manifolds that combines interpolation of on with uniform approximation on compact subsets of of another given continuous map that is holomorphic on . Under the further assumption that is an Oka manifold we obtain a corollary that combines Rudin-Carleson interpolation of a continuous map on with Runge approximation of on a compact set without any holes on which is holomorphic.
