Symmetries of linearized gravity from adjoint operators
Steffen Aksteiner, Thomas Bäckdahl
Based on operator identities and their formal adjoints, we derive two symmetry operators for the linearized Einstein operator on vacuum backgrounds of Petrov type D and in particul…

New identities for linearized gravity on the Kerr spacetime
Steffen Aksteiner, Lars Andersson, Thomas Bäckdahl
In this paper we derive a differential identity for linearized gravity on the Kerr spacetime and more generally on vacuum spacetimes of Petrov type D. We show that a linear combina…
