Perturbative approach to the two-dimensional quantum gravity
Abstract
The main part of this presentation is a review of the previous original works on the perturbative covariant approach to the 2-dimensional quantum gravity. We discuss the renormalization of the two-dimensional dilaton gravity in a harmonic gauge, the form of the quantum corrections to the classical potential, and the conditions of Weyl invariance in a theory of string coupled to 2d quantum gravity.
