要旨:
In this paper we prove a new identity for linearized gravity on vacuum
spacetimes of Petrov type D. The new identity yields a covariant version of the
Teukolsky-Starobinsky identities for linearized gravity, which in addition to
the two classical identities for the extreme linearized Weyl scalars includes
three additional equations. By analogy with the spin-1 case, we expect the new
identity to be relevant in deriving new conservation laws for linearized
gravity.
