PRECESSIONS OF OPPOSITE CHIRALITY FOR THE SPIN VECTOR IN A RIEMANN-CARTAN FRAMEWORK

The transpose of a given non-symmetric connection is also a connection. In a manifold endowed with torsion as a field, the somewhat intriguing conclusion is reached that, in the case of completely antisymmetric torsion, these two distinct connections give rise to precessions of opposite chirality for the spin vector. The physical relevance of this effect is discussed.
