The Roper-Suffridge extension operator provides a way of extending a (locally) univalent functionfεH(U)to a (locally) biholomorphic mappingF∈H(Bn). In this paper, we give a simplified proof of the Roper-Suffridge theorem: iffis convex, then so isF. We also show that iff∈S*, theFis starlike and that iffis a Bloch function inU, thenFis a Bloch mapping onBn. Finally, we investigate some open problems.
