Comments on Killing and Killing-Yano TensorsUlf Lindstrom Abstract: Killing-Yano tensors (KYTs) have long been studied in various settings. They can be thought of as square roots of Killing tensors with which they share some properties. In particular they are relevant to gravity, supergravity and string theory for finding hidden symmetries for particles and backgrounds, for separating variables in Hamilton-Jacobi equations and for finding the symmetries of the Dirac equation and its super extensions. I will focus on their use for constructing conserved charges. |
