Dimensional reduction of AdS3 Chern-Simons gravity: Schwarzian and affine boundary theories

Goffredo Chirco, Lucio Vacchiano, Patrizia Vitale

We study a symmetry-reduced sector of $Ad{S}_3$ gravity formulated as an $SO(2,2)$ Chern--Simons theory on a three-dimensional manifold with toroidal boundary. The reduction is imple…
