A bstractThe asymptotically flat structure of N=20$$ \mathcal{N}=\left(2,0\right) $$ supergravity in three spacetime dimensions is explored. The asymptotic symmetries are found to be spanned by an extension of the super-BMS3 algebra, endowed with two independent affine û(1) currents of electric and magnetic type. These currents are associated to U(1) fields being even and odd under parity, respectively. Remarkably, although the U(1) fields do not generate a backreaction on the metric, they… 
New $$ \mathcal{N} $$ = 2 SuperBMS3 algebra and invariant dual theory for 3D supergravity
Abstract We have constructed a two dimensional theory dual to 3D asymptotically flat Supergravity in presence of two supercharges with(out) internal R-symmetry. The duals in both the cases are

Superconformal Bondi-Metzner-Sachs Algebra in Three Dimensions.
An explicit canonical realization of the conformal extension of BMS_{3} is shown to emerge from the asymptotic structure of conformal gravity in three dimensions, endowed with a new set of boundary conditions.
