Abstract

We investigate the string-inspired action for two-dimensional gravity with the addition of dynamical torsion and obtain the most general static black hole solutions. We also consider the Hamiltonian formulation of the model and discuss its symmetries, showing that it can be considered as a gauge theory of a nonlinear generalization of the two-dimensional Poincare algebra. Finally, we briefly discuss the quantization of the theory in the Dirac formalism.
