Supersymmetric 3D gravity with torsion: asymptotic symmetries
Abstract:
We study the structure of asymptotic symmetries in N=1+1
supersymmetric extension of three-dimensional gravity with torsion.
Using a natural generalization of the bosonic anti-de Sitter
asymptotic conditions, we show that the asymptotic Poisson bracket
algebra of the canonical generators has the form of two independent
super-Virasoro algebras with different central charges.
