Abstract

Abstract The 2D model of gravity with zweibeins e a and the Lorentz connection one-form ω a b as independent gravitational variables is considered and it is shown that the classical equations of motion are exactly integrated in a coordinate system determined by the components of the 2D torsion. The metric can be written in a Schwarzschild-like form. The general solution describes a black hole of charged type in asymptotic de Sitter space-time. The ADM mass and the Hawking temperature of the black hole are calculated.
