Asymptotic dynamics in 3D gravity with torsion

We study the nature of boundary dynamics in teleparallel 3D gravity. The asymptotic field equations with anti de Sitter boundary conditions yield only two nontrivial boundary modes, associated with a conformal field theory with a classical central charge. After showing that the teleparallel gravity can be formulated as a Chern-Simons theory, we identify the dynamical structure at the boundary as the Liouville theory.
