Three-dimensional manifolds admitting Lorentz metrics are studied. The first part of the paper gives a classification of the Ricci and curvature tensors and also of the conformal (Schouten–Cotton–York) tensor. The second part of the paper investi

A geometrical proof is provided of a necessary and sufficient condition for a conformal Killing vector field with fixed point on a pseudo-Riemannian manifold to be homothetic or Killing with respect to a locally defined metric conformally related to

Given a manifold with a conformal metric [g] and a non-degenerate proper distribution W we construct a unique connection, with natural restriction on the torsion, which preserves both [g] and W. Moreover, this connection (which is essentially a Weyl
