Locally conformally Berwald manifolds and compact quotients of reducible manifolds by homotheties
speaker: Yuri A. Nikolayevsky (La Trobe University, Melbourne)abstract: Our aim is to understand the structure of locally conformally Berwald metrics on closed manifolds which are not globally conformally Berwald. We first show, using the Binet-Legendre metric, that the characterisation of such metrics is equivalent to characterising incomplete, simply-connected, Riemannian manifolds with reducible holonomy group whose quotient by a group of homotheties is closed. We then prove a de Rham type splitting theorem which states that such a manifold is a cylinder over an incomplete non-flat manifold.
This is a joint work with by Vladimir Matveev.
