Phase space path integral in curved space
arXiv:gr-qc/0009015 · doi:10.1142/S0217751X01005936
Abstract
Phase space path integral is worked out in a riemannian geometry, by employing a prescription for the infinitesimal propagator that takes riemannian normal coordinates and momenta on an equal footing. The operator ordering induced by this prescription leads to the DeWitt curvature coupling in the Schrodinger equation.
