Macroscopic n - Loop Amplitude for Minimal Models Coupled to Two - Dimensional Gravity — Fusion Rules and Interactions —
We investigate the structure of the macroscopic n-loop amplitude obtained from the two-matrix model at the unitary minimal critical point (m+1, m). We derive a general formula for the n-resolvent correlator at the continuum planar limit whose inverse Laplace transform provides the amplitude in terms of the boundary lengths ℓ i and the renormalized cosmological constant t. The amplitude is found...
متن کاملFusion rules and macroscopic loops from discretized approach to two - dimensional gravity 1
We investigate the multi-loop correlators and the multi-point functions for all of the scaling operators in unitary minimal conformal models coupled to two-dimensional gravity from the two-matrix model. We show that simple fusion rules for these scaling operators exist, and these are summarized in a compact form as fusion rules for loops. We clarify the role of the boundary operators and discus...

I briefly summarize recent results on classical and quantum dilaton gravity in 1+1 dimensions.
متن کاملTwo-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 کاملTwo-Dimensional Dilaton Gravity
Actions for D = 2, N = 2 supergravity coupled to a scalar field are calculated, and it is shown that the most general power-counting renormalizable dilaton gravity action has an N = 2 locally supersymmetric extension. The presence of chiral terms in the action leads one to hope that non-renormalization theorems similar to those in global SUSY will apply; this would eliminate some of the renorma...
