The existence of a recurrent spinor field on a pseudo-Riemannian spin manifold is closely related to the existence of a parallel 1-dimensional complex subbundle of the spinor bundle of . We characterize the following simply connected pseudo-Riemannian manifolds admitting such subbundles in terms of their holonomy algebras: Riemannian manifolds; Lorentzian manifolds; pseudo-Riemannian manifolds with irreducible holonomy algebras; pseudo-Riemannian manifolds of neutral signature admitting two complementary parallel isotropic distributions.
