Backward Ricci Flow on Locally Homogeneous Three-manifolds

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/221725In this paper, we study the backward Ricci flow on locally homogeneous 3-manifolds. We describe the long time behavior and show that, typically and after a proper re-scaling, there is convergence to a sub-Riemannian geometry. A similar behavior was observed by the authors in the case of the cross curvature flow.17 pages, references added, final versionDifferential Geometry53C44Backward Ricci Flow on Locally Homogeneous Three-manifoldstext
