Generalized Symmetries For Generalized Gravitons

Understand

We construct generalized symmetries for linearized Einstein gravity in arbitrary dimensions.

• First-principle considerations in QFT force generalized symmetries to appear in dual pairs.
• Verifying this prediction helps us find the full set of non-trivial conserved charges -- associated, in equal parts, with 2-form and $(D-2)$-form currents.
• Their total number is $D(D+1)$.
