An Approach to Quantum 2D Gravity (2206.05172v1)
Published 10 Jun 2022 in hep-th
Abstract: We consider a model of 2D gravity with the action quadratic in curvature and represent path integrals as integrals over the SL(2, R) invariant Gaussian functional measure. We reduce these path integrals to the products of Wiener path integrals and calculate the correlation function of the metric in the first perturbative order.
