Query: Boundary structure of General Relativity in tetrad variables   An explicit, geometric description of the first-class constraints and their
Poisson brackets for gravity in the Palatini-Cartan formalism (in space-time
dimension greater than three) is given. The corresponding Batalin-
Fradkin-Vilkovisky (BFV) formulation is also developed.
