Unfree gauge symmetry in the Hamiltonian formalism
arXiv:1911.11548 · doi:10.1016/j.physletb.2020.135208
Abstract
The constrained Hamiltonian formalism is worked out for the theories where the gauge symmetry parameters are unfree, being restricted by differential equations. The Hamiltonian BFV-BRST embedding is elaborated for this class of gauge theories. The general formalism is exemplified by the linearized unimodular gravity.
