Harmonic morphisms on conformally flat 3-spheres

Differential Geometry 2013-10-22 v1

Abstract

We show that under some non-degeneracy assumption the only submersive harmonic morphism on a conformally flat 33-sphere is the Hopf fibration. The proof involves an appropriate use the Chern-Simons functional.
