Higher rank Stackel-Killing tensors of various spacetimes
Hidden symmetries of the Goryachev-Chaplygin and Kovalevskaya gyrostat spacetimes, as well as the Brdicka-Eardley-Nappi-Witten pp-waves are studied. We find out that these spacetimes possess higher rank Stackel-Killing tensors and that in the case of the pp-wave spacetimes the symmetry group of the Stackel-Killing tensors is the well-known Newton-Hooke group.
