论文摘要
我们考虑（2+1）维度的最小超级重力背景。我们修复了重力田场的下降条件，以固定渐近相空间。然后，使用Chern-Simons公式，我们为该理论得出了渐近的对称代数。下降条件对相位空间施加了约束，这将Chern Simons理论降低为WZW模型。进一步的约束将其减少到边界上的超级liouville理论。这可以将其视为批量超级实力理论的经典双重。
We consider minimal supergravity on (2+1)dimensional de-Sitter background. We fix the fall-off conditions for gravitini fields in order to fix the asymptotic phase space. Using the Chern-Simons formulation, we then derive the asymptotic symmetry algebra for this theory. The fall-off conditions impose constraints on the phase space which reduces the Chern Simons theory to a WZW model. Further constraints reduce it to a super-Liouville theory at the boundary. This can be treated as a classical dual for the supergravity theory in the bulk.
