Weba non-constant harmonic morphism is a submersion except on a nowhere dense subset of critical points where the di erential has rank zero. Thus, if n>m, there are no non-constant harmonic morphisms. 1. If n= 1, horizontal weak conformality is automatic and so a harmonic morphism is just a harmonic map. Thus, if N= R, a harmonic morphism Webin a Riemannian manifold is a harmonic morphism with totally geodesic ﬁbres (see Proposition 4.2). In this paper we show that the converse holds, i.e., for any immersed surface in a Riemannian manifold, if the projection map of the unit normal bundle is a harmonic morphism, then the surface can be split into two parts, one is minimal and the ... mott macdonald offices london
