Duality symmetry and dynamics on finite null boundaries
Gianfranco De Simone
In this work, we derive a set of boost-weighted functionals of the metric, with , which transform semi-covariantly under the action of the near-horizon sym…

Near-Horizon Symmetries in Einstein-Maxwell theory
Gianfranco De Simone
This manuscript aims to provide a comprehensive derivation of the Einstein-Maxwell charges and fluxes in the near-horizon region of a four-dimensional non-extremal black hole, with…
