2D-gravity and the Hamilton-Jacobi formalism
arXiv:gr-qc/0211092
Abstract
Hamilton-Jacobi formalism is used to study 2D-gravity and its SL(2, R) hidden symmetry. If the contribution of the surface term is considered the obtained results coincide with those given by the Dirac and Faddeev-Jackiw approaches.
