Three dimensional manifolds all of whose geodesics are closed

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/231213We present some results concerning the Morse Theory of the energy function on the free loop space of the three sphere for metrics all of whose geodesics are closed. We also explain how these results relate to the Berger Conjecture in dimension three.16 pagesDifferential GeometryAlgebraic Topology58E10Three dimensional manifolds all of whose geodesics are closedtext
