Radiative Asymptotic Symmetries of 3D Einstein-Maxwell Theory
Jorrit Bosma, Marc Geiller, Sucheta Majumdar +1
We study the null asymptotic structure of Einstein-Maxwell theory in three-dimensional (3D) spacetimes. Although devoid of bulk gravitational degrees of freedom, the system admits…

BMS symmetry in gravity: Front form versus Instant form
Sudarshan Ananth, Sucheta Majumdar
In General Relativity, the allowed set of diffeomorphisms or gauge transformations at asymptotic infinity forms the BMS group, an infinite-dimensional extension of the Poincaré gro…
