Spectrum of Two-Dimensional (Super)Gravity∗
نویسندگان
چکیده
We review the BRST analysis of the system of a (super)conformal matter coupled to 2D (super)gravity. The spectrum and its operator realization are reported. In particular, the operators associated with the states of nonzero ghost number are given. We also discuss the ground ring structure of the super-Liouville coupled to ĉ = 1 matter. In appendices, hermiticities, states for c < 1 conformal matter coupled to gravity and the proof for the spectrum are discussed. Submitted to: Progress of Theoretical Physics Supplement An expanded version of the talk given at the workshop on Developments in String Theory and New Field Theories, Yukawa Institute for Theoretical Physics, Kyoto University, September 9–12, 1991.

General treatment of anomalies in ( 1 , 0 ) and ( 1 , 1 ) two - dimensional super - gravity
In this paper we discuss the interplay among (super-)coordinate, Weyl and Lorentz anomaly both in chiral and non-chiral super-gravity represented by (1, 0) and (1, 1) two-dimensional models. It is shown that for this purpose two regu-larization dependent parameters are needed in the effective action. We discuss in full generality the regularization ambiguities of the induced effective action an...
متن کاملFivebranes from gauge theory
We study theories with sixteen supercharges and a discrete energy spectrum. One class of theories has symmetry group SU(2|4). They arise as truncations of N = 4 super Yang Mills. They include the plane wave matrix model, 2+1 super Yang Mills on R × S2 and N = 4 super Yang Mills on R × S/Zk. We explain how to obtain their gravity duals in a unified way. We explore the regions of the geometry tha...
متن کاملSpherically Symmetric Solutions in a New Braneworld Massive Gravity Theory
In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
متن کاملChiral gravity in two dimensions
It is shown that conformal matter with cL 6= cR can be consistently coupled to two-dimensional ‘frame’ gravity. The theory is quantized, following David, and Distler and Kawai, using the derivation of their ansatz due to Mavromatos and Miramontes, and D’Hoker and Kurzepa. New super-selection rules are found by requiring SL(2,C) invariance of correlation functions on the plane. There is no analo...
متن کاملIrreversibility of the Renormalization Group Flow in Two Dimensional Quantum Gravity
We argue that the torus partition sum in 2d (super) gravity, which counts physical states in the theory, is a decreasing function of the renormalization group scale. As an application we chart the space of (ĉ ≤ 1) c ≤ 1 models coupled to (super) gravity, confirming and extending ideas due to A. Zamolodchikov, and discuss briefly string theory, where our results imply that the number of degrees ...
