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

An exact formula that relates standard zeta functions and so-called hatted in all orders of perturbation theory is presented. This based on the Landau-Khalatnikov-Fradkin transformation

Using a complex representation of planar motions, we show that the dynamical conserved quantities associated to isotropic harmonic oscillator (Fradkin–Jauch–Hill tensor) and Kepler's pro...
