摘要:

本文考虑由反对称挠联导出的Dirac算子的对称性。我们发现,广义共形Killing-Yano张量引起的对称运营商的无质量狄拉克方程,提供了一个明确给定的异常消失。我们表明,这引起的狄拉克算子的对称性的情况下,强Kahler挠(KT)和强超Kahler挠(HKT)流形。

英文摘要:

In this paper, we consider the symmetries of the Dirac operator derived from a connection with skew-symmetric torsion. We find that the generalized conformal Killing-Yano tensors give rise to symmetry operators of the massless Dirac equation, provided an explicitly given anomaly vanishes. We show that this gives rise to symmetries of the Dirac operator in the case of strong Kahler with torsion (KT) and strong hyper-Kahler with torsion (HKT) manifolds.
