Axi-Dilaton Gravity in D \geq 4 Dimensional Space-Times with Torsion
  We study models of axi-dilaton gravity in space-time geometries with torsion. We discuss conformal re-scaling rules in both Riemannian and non-Riemannian formulations. We give static, spherically symmetric solutions and examine their singularity structure.
