Metrisability of three-dimensional path geometries
Dunajski, Maciej Lukasz; Eastwood, Michael (SpringerEuropean Journal of Mathematics, 2016-03-08)Given a projective structure on a three-dimensional manifold, we find explicit obstructions to the local existence of a Levi-Civita connection in the projective class. These obstructions are given by projectively invariant ...
