| Feb 21, 2015 at 15:02 | comment | added | Zero | How does one prove that given D. a double cover of a manifold S, and a constant curvature metric for D, you can 'push' the metric trough the covering map to obtain a constant-curvature metric for S? | |

| Feb 21, 2015 at 14:32 | comment | added | Zero | Uniformization applies to Riemann surfaces .I'm asking for 2d manifolds in general. As far as I know, you can assign a complex structure to a manifold if it's orientable. It would need an extension to non-orientable manifolds. | |
