| Nov 17, 2010 at 3:05 | comment | added | macbeth | A variant of this question was asked in February: mathoverflow.net/questions/14548/…. In an answer there, Dmitri mentions notes of Donaldson www2.imperial.ac.uk/~skdona/GEOMETRICANALYSIS.PDF which sketch (p48) a non-complex-analysis, non-Ricci proof. The argument is apparently: show that a Riemannian manifold diffeo to $S^2$ must admit a "harmonic spinor with one pole," then take the norm of this harmonic spinor as a conformal rescaling and get a flat metric on the complement of the pole. | |
