Regge Dilaton Gravity from BF Theory
Florian Girelli, Christopher Pollack
In this work we investigate the relation between gauge and geometric descriptions of two-dimensional dilaton gravity at the level of discrete path integrals. We develop a Regge dis…

A Covariant Formulation of Logarithmic Supertranslations at Spatial Infinity
Florian Girelli, Simon Langenscheidt, Giulio Neri +2
We investigate the asymptotic symmetries of asymptotically flat spacetimes at spatial infinity. We propose a new symplectic structure and conservative boundary conditions in a poly…
