Gauge Formulation of the Spinning Black Hole in (2+1)-Dimensional Anti-de Sitter Space

arXiv:gr-qc/9211013 · doi:10.1103/PhysRevD.48.3606

Abstract

We compute the group element of SO(2,2) associated with the spinning black hole found by Bañados, Teitelboim and Zanelli in (2+1)-dimensional anti-de Sitter space-time. We show that their metric is built with SO(2,2) gauge invariant quantities and satisfies Einstein's equations with negative cosmological constant everywhere except at . Moreover, although the metric is singular on the horizons, the group element is continuous and possesses a kink there.
