The homotopy momentum map of general relativity
arXiv:2103.07670 · doi:10.1093/imrn/rnac087
Abstract
We show that the action of spacetime vector fields on the variational bicomplex of general relativity has a homotopy momentum map that extends the map from vector fields to conserved currents given by Noether's first theorem to a morphism of -algebras.
