4D Palatini-Cartan Gravity in Hamiltonian Form
Giovanni Canepa, Alberto S. Cattaneo
In this note the Hamiltonian formulation of four-dimensional gravity, in the Palatini-Cartan formalism, is recovered by elimination of an auxiliary field appearing as part of the c…

BV Pushforward of Palatini-Cartan gravity
Giovanni Canepa, Alberto S. Cattaneo
The goal of this note is to show that the standard BV formulation of gravity in the Palatini-Cartan formalism is equivalent, using a BV pushforward, to an AKSZ-like version compati…

Gravitational Constraints on a Lightlike boundary
Giovanni Canepa, Alberto S. Cattaneo, Manuel Tecchiolli
We analyse the boundary structure of General Relativity in the coframe formalism in the case of a lightlike boundary, i.e., when the restriction of the induced Lorentzian metric to…
