Equivalence of BRST cohomologies for 2-d black hole and c = 1 Liouville theory
نویسنده
چکیده
We study the relation between the SL(2, R)/U(1) black hole and the c = 1 Liouville theory. A deformation, which interpolates the BRST operators of both models, is explicitly constructed. This interpolation is isomorphic, and the physical spectrum of the black hole is equivalent to that of the c = 1 model tensored by a topological U(1)/U(1) model. Some implications of the deformation are discussed. E-mail address: [email protected] E-mail address: [email protected]

The Spectrum of the 2d Black Hole
or Does the 2D black hole have tachyonic or W–hair? Abstract We solve the equations of motion of the tachyon and the discrete states in the background of Witten's semiclassical black hole and in the exact 2D dilaton-graviton background of Dijkgraaf et al. We find the exact solutions for weak fields, leading to conclusions in disagreement with previous studies of tachyons in the black hole. Dema...
متن کاملThe Ground Ring of N = 2 Minimal String Theory
We study the N = 2 string theory or the N = 4 topological string on the deformed CHS background. That is, we consider the N = 2 minimal model coupled to the N = 2 Liouville theory. This model describes holographically the topological sector of Little String Theory. We use degenerate vectors of the respective N = 2 Verma modules to find the set of BRST cohomologies at ghost number zero–the groun...
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 کاملLiouville Theory Perturbed by the Black - Hole Mass Operator
We discuss the properties of the Liouville theory coupled to the c = 1 matter when perturbed by an operator, the screening operator of the SL(2;R) current algebra, which is supposed to generate the mass of the two-dimensional black hole. Mimicking the standard KPZ scaling theory of the Liouville system perturbed by the cosmological constant operator, we develop a scaling theory of correlation f...
متن کاملDuality of the Fermionic 2d Black Hole and N = 2 Liouville Theory as Mirror Symmetry
We prove the equivalence of the SL(2,R)/U(1) Kazama-Suzuki model, which is a fermionic generalization of the 2d Black Hole, and N = 2 Liouville theory. We show that this duality is an example of mirror symmetry. The essential part of the derivation is to realize the fermionic 2d Black Hole as the low energy limit of a gauged linear sigma-model. Liouville theory is obtained by dualizing the char...
