Description

Motivated by the current research of generalized symmetries and the construc-
tion of conserved charges in pure Einstein gravity linearized over Minkowski spacetime in
Cartesian coordinates, we investigate, from a purely classical point of view, the construction
of these charges in a coordinate- and frame-independent language in order to generalize
them further. We show that all the charges constructed in that context are associated to the
conformal Killing-Yano 2-forms of Minkowski spacetime. Furthermore, we prove that those
associated to closed conformal Killing-Yano 2-forms are identical to the charges constructed
by Kastor and Traschen for their dual Killing-Yano (d − 2)-forms. We discuss the number
of independent and non-trivial gravitational charges that can be constructed in this way
