Asymptotic structure of the Pauli–Fierz theory in four spacetime dimensions
Abstract The asymptotic structure of the Pauli–Fierz theory at spatial infinity is investigated in four spacetime dimensions. Boundary conditions on the massless spin-2 field that are invariant under an infinite-dimensional group of non-trivial ‘improper’ gauge symmetries are given. The compatibility of these boundary conditions with invariance of the theory under …
