Ultralocal energy density in massive gravity
arXiv:1106.5709
Abstract
We provide a space-time covariant Hamiltonian treatment for a finite-range gravitational theory. The Kuchar approach is used to demonstrate the bimetric picture of space-time in its most transparent form. This Hamiltonian formalism is applied for the straightforward realization of the Poincaré algebra in Dirac brackets. It uncovers the simplest form of the Poincaré generators expressed as spatial integrals of ultralocal quantities constructed pure algebraically by means of the two space-time metrics.
