Ricci flow with surgery on open 3-manifolds with bounded geometry

speaker: Laurent Bessières (Institut Joseph Fourier, Grenoble)

abstract: We develop a variant of Perelman’s Ricci flow with surgery, on open complete 3-manifolds with bounded geometry. As an application, we classify such manifolds with scalar curvature R > a >0: each one is a connected sum (infinite) of copies of a finite number of spherical manifolds and S² x S^1. Joint work with S. Maillot and G. Besson.
