SUMMARY:Centre for Geometric Analysis Seminar Series
DESCRIPTION:\nSpeaker\nDr Philip Schrader (UWA) \n\n\n\nTitle\nGradient flows of length\nAbstract\nThe classical curve shortening flow is a length gradient flow which evolves planar curves in the (negative) normal direction proportional to curvature. To define a gradient flow of the length requires a Riemannian metric on the space of curves and in the case of the curve shortening flow the metric is an invariant L^2 metric. The space of curves being infinite dimensional\, not all Riemmanian metrics are equivalent\, and in fact it was proved by Michor and Mumford that the L^2 metric gives a trivial distance. In this talk I will explain Michor and Mumfordâ€™s proof\, and present some results from investigating the length gradient flow associated with an H^1 metric on the space of curves (joint work with G. Wheeler and V.M. Wheeler).\n\n
