Constraints in two-dimensional Dilaton Gravity with Fermions
arXiv:hep-th/0512267
Abstract
Generalized Dilaton Theories in two dimensions coupled to Dirac fermions are subjected to constraint analysis. Three first class secondary constraints are found, corresponding to one local Lorentz symmetry and two diffeomorphisms. Moreover, the system also yields second class constraints from the fermions. The algebra of first class constraints is calculated in some detail, and is found to be related to the classical Virasoro algebra.
