On the Liouville three-point function
The recently proposed expression for the general three point function of exponential fields in quantum Liouville theory on the sphere is considered. By exploiting locality or crossing symmetry in the case of those four-point functions, which may be expressed in terms of hypergeometric functions, a set of functional equations is found for the general three point function. It is shown that the ex...
متن کاملThree-Point Function in Perturbed Liouville Gravity
Three-point correlation function in perturbed conformal field theory coupled to twodimensional quantum gravity (perturbed Liouville gravity) is explicitly computed by using the free field approach. The representation considered here is the one recently proposed in [1] to describe the string theory in AdS3 space. Consequently, this computation extends previous results which presented free field ...
متن کاملThree-point Functions in Sine-Liouville Theory
We calculate the three-point functions in the sine-Liouville theory explicitly. The same calculation was done in the (unpublished) work of Fateev, Zamolodchikov and Zamolodchikov to check the conjectured duality between the sine-Liouville and the SL(2,R)/U(1) coset CFTs. The evaluation of correlators boils down to that of a free-field theory with a certain number of insertion of screening opera...
متن کاملCorrelators in Timelike Bulk Liouville Theory
Liouville theory with a negative norm boson and no screening charge corresponds to an exact classical solution of closed bosonic string theory describing time-dependent bulk tachyon condensation. A simple expression for the two point function is proposed based on renormalization/analytic continuation of the known results for the ordinary (positive-norm) Liouville theory. The expression agrees e...
متن کاملFour-point function in Super Liouville Gravity
We consider the 2D super Liouville gravity coupled to the minimal superconformal theory. We analyze the physical states in the theory and give the general form of the n-point correlation numbers on the sphere in terms of integrals over the moduli space. The threepoint correlation numbers are presented explicitly. For the four-point correlators, we show that the integral over the moduli space re...
