Two-Dimensional Quantum Gravity
We show equivalence between the standard weak coupling regime c > 25 of the the two-dimensional quantum gravity and regime h < 1/2 of the original geometric approach of Polyakov [1, 2], developed in [3, 4, 5]. 1 In this letter I shall demonstrate the equivalence of two approaches to the twodimensional quantum gravity. The first approach, called geometric, goes back to Polyakov’s original discov...
متن کاملScaling Functions for Baby Universes in Two-Dimensional Quantum Gravity
We apply the recently proposed transfer matrix formalism to 2-dimensional quantum gravity coupled to (2, 2k − 1) minimal models. We find that the propagation of a parent universe in geodesic (Euclidean) time is accompanied by continual emission of baby universes and derive a distribution function describing their sizes. The k → ∞ (c → −∞) limit is generally thought to correspond to classical ge...
متن کاملCorrelation Functions in Two-Dimensional Dilaton Gravity
The Liouville approach is applied to the quantum treatment of the dilaton gravity in two dimensions. The physical states are obtained from the BRST cohomology and correlation functions are computed up to three-point functions. For the N = 0 case (i.e., without matter), the cosmological term operator is found to have the discrete momentum that plays a special role in the c = 1 Liouville gravity....
متن کاملTwo-Dimensional Quantum Gravity in Temporal Gauge
We propose a new type of gauge in two-dimensional quantum gravity. We investigate pure gravity in this gauge, and find that the system reduces to quantum mechanics of loop length l. Furthermore, we rederive the c=0 string field theory which was discovered recently. In particular, the pregeometric form of the Hamiltonian is naturally reproduced. To be published in Nuclear Physics B ∗ e-mail addr...
متن کاملDiscrete States in Two-Dimensional Quantum Gravity∗
We review the recent developments in the two-dimensional (super)gravity coupled to c(ĉ) ≤ 1 (super)conformal matter in the conformal gauge. Starting from a pedagogical account of the conformal anomaly in such a system, we show how the system is transformed into the representation in terms of the (free) Liouville field. Some perturbative justification is given to this procedure. The physical sta...
