广义欧几里德Taub-NUT度规的引力反常和轴反常

Gravitational and axial anomalies for generalized Euclidean Taub-NUT metrics

Ion I. Cotăescu, Sergiu Moroianu, Mihai Visinescu

摘要:

引力异常的广义欧几里德Taub-NUT度量承认隐藏的对称性类似的Runge-Lenz向量的开普勒型问题。为了评估轴向异常,狄拉克算子的指数为这些度规与APS边界条件计算。Killing-Yano张量的作用进行了讨论,这两种类型的量子异常。

英文摘要:

The gravitational anomalies are investigated for generalized Euclidean Taub-NUT metrics which admit hidden symmetries analogous to the Runge-Lenz vector of the Kepler-type problem. In order to evaluate the axial anomalies, the index of the Dirac operator for these metrics with the APS boundary condition is computed. The role of the Killing-Yano tensors is discussed for these two types of quantum anomalies.
