具有循环旋量场的伪黎曼流形

Pseudo-Riemannian manifolds with recurrent spinor fields

Anton S. Galaev

摘要:

伪黎曼自旋流形$(M,g)$上旋量场的存在性与$(M,g)$旋量丛的平行1维复子丛的存在性密切相关。本文用holonomy代数刻画了下列单连通伪黎曼流形:黎曼流形; Lorentz流形;具有不可约holonomy代数的伪黎曼流形;具有两个互补平行各向同性分布的伪黎曼流形。

英文摘要:

The existence of a recurrent spinor field on a pseudo-Riemannian spin manifold $(M,g)$ is closely related to the existence of a parallel 1-dimensional complex subbundle of the spinor bundle of $(M,g)$. 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.
