BRST cohomology ring in 2D gravity coupled to minimal models
The ring structure of Lian-Zuckerman states for (q, p) minimal models coupled to gravity is shown to beR = R0⊗C[w,w] where R0 is the ring of ghost number zero operators generated by two elements and w is an operator of ghost number −1. Some examples are discussed in detail. For these models the currents are also discussed and their algebra is shown to contain the Virasoro algebra. † Address aft...
متن کاملCorrelation Functions of (2k−1, 2) Minimal Matter Coupled to 2D Quantum Gravity
We compute N -point correlation functions of non-unitary (2k−1, 2) minimal matter coupled to 2D quantum gravity on a sphere using the continuum Liouville field approach. A gravitational dressing of the matter primary field with the minimum conformal weight is used as the cosmological operator. Our results are in agreement with the correlation functions of the one-matrix model at the k-th critic...
متن کاملCanonical Theory of 2D Gravity Coupled to Conformal Matter
A canonical quantization for two dimensional gravity models, including a dilaton gravity model, is performed in a way suitable for the light-cone gauge. We extend the theory developed by Abdalla et.al.[1] and obtain the correlation functions by using the screening charges of the symmetry algebra. It turns out that the role of the cosmological constant term in the Liouville theory is played by t...
متن کاملExact Solution Of 2D Poincaré Gravity Coupled To Fermion Matter
The 2D model of gravity with zweibeins ea and the Lorentz connection one-form ω a b as independent gravitational variables coupled to 2d massless Dirac matter is considered. It is shown that the classical equations of motion are exactly integrated in the case of chiral fermions. ∗ e-mail: [email protected]
متن کاملA Topological Model for Two-dimensional Gravity Coupled to Matter
Starting from a topological gauge theory in two dimensions with symmetry groups ISO(2, 1), SO(2, 1) and SO(1, 2) we construct a model for gravity with non-trivial coupling to matter. We discuss the equations of motion which are connected to those of previous related models but incorporate matter content. We also discuss the resulting quantum theory and finally present explicit formulæ for topol...
