| Sep 25, 2013 at 16:11 | comment | added | Ian Agol | Hamilton states in his original paper that the Ricci tensor is analogous to a Laplacian of the metric, and therefore has similarities to a parabolic PDE. If one wants to find a flow on metrics, this is the simplest symmetric 2-tensor to write down in terms of the curvature. One can modify it by other terms, like scalar curvature times the metric, but this is not weakly parabolic, or the traceless Ricci tensor, but this just rescales the Ricci flow. In fact, Hamilton said when he originally defined the flow, he didn't know the correct sign until he tried proving local existence. | |
