| Apr 15, 2016 at 20:48 | comment | added | Ben McKay | You can write out the Ptolemaic coordinates on the sphere with an explicit expression for the Riemannian metric, so that dilation in those coordinates gives a very explicit compression toward the north pole. You can see explicitly an orthonormal frame and how it transforms in those coordinates, I think, so you should be able to see how shape operators transform. | |
