Supersymmetric 3D gravity with torsion: asymptotic symmetries
arXiv:gr-qc/0702121 · doi:10.1088/0264-9381/24/15/011
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.
