This particular form of the action reproduces the standard results of black hole thermodynamics and determines that the algebra of charges of diffeomorphisms at the horizon is the Virasoro algebra.enSupergravityGravitationBlack HolesCharges and the boundary in Chern-Simons gravityArtÃculoAttribution 4.0 International (CC BY 4.0)10.1103/PhysRevD.73.044023
