Two notes about spin in absolute parallelism spaces
The authors investigate spin phenomenon in curved spaces. They find two results: 1) An affinely connected space, in which one can write the Dirac equation for spin 1/2-particles moving in a gravitational field, in an absolute parallelism space. 2) If the torsion vanishes, the absolute parallelism space is a flat one. Some concluding remarks concern the limiting case of general relativity as spin (or torsion) vanishes.
