Covariant Spin Structure

arXiv:gr-qc/9711043 · doi:10.1063/1.532496

Abstract

Every Dirac spin structure on a world manifold is associated with a certain gravitational field, and is not preserved under general covariant transformations. We construct a composite spinor bundle such that any Dirac spin structure is its subbundle, and this bundle admits general covariant transformations.
