Abstract
A theory of gravity with torsion is examined in which the torsion tenser is constructed from the exterior derivative of an antisymmetric rank-two pote ntial plus the dual of the gradient of a scalar field. Field equations for the theory are derived by demanding that the action be stationary under var iations with respect to the metric, the antisymmetric potential, and the sc alar field. A material action is introduced and the equations of motion are derived. The correct conservation law for rotational angular momentum plus spin is observed to hold in this theory.
