Abstract:

The Ricci flow on a surface is an intrinsic evolution of the metric converging to a constant curvature metric within the conformal class. It can be seen as an (infinite-dimensional) gradient flow. We introduce a natural 'Langevinization' of that flow, thus constructing an SPDE with invariant measure expressed in terms of Liouville Conformal Field Theory. Joint work with Hao Shen (Wisconsin)
