Conformally Coupled Scalar in Rotating Black Hole Spacetimes

open access: yes, 2020
We demonstrate separability of conformally coupled scalar field equation in general (off-shell) Kerr-NUT-AdS spacetimes in all dimensions. The separability is intrinsically characterized by the existence of a complete set of mutually commuting conformal ...
