Dirac-Type Operators on Curved Spaces and the Role of Killing–Yano Tensors
M. Visinescu National Institute for Physics and Nuclear Engineering
Abstract:
We consider the Dirac equation in curved backgrounds and investigate the role of Killing–Yano tensors in constructing Dirac-type operators. The general results are applied to the case of the four-dimensional Euclidean Taub–NUT space. We investigate the gravitational anomalies for generalized Euclidean Taub–NUT metrics that admit hidden symmetries analogous to the Runge–Lenz vector of the Kepler-type problem.
Keywords:
Dirac operator, Killing–Yano tensors, Taub–NUT space, hidden symmetries.
