3D gravity with torsion as a Chern-Simons gauge theory
arXiv:gr-qc/0307078 · doi:10.1103/PhysRevD.68.104023
Abstract
We show that topological 3D gravity with torsion can be formulated as a Chern-Simons gauge theory, provided a specific parameter, known as the effective cosmological constant, is negative. In that case, the boundary dynamics of the theory corresponding to anti-de Sitter boundary conditions is described by a conformal field theory with two different central charges.
