Correlation Functions and Vertex Operators of Liouville Theory
arXiv:hep-th/0311202 · doi:10.1016/j.physletb.2003.11.067
Abstract
We calculate correlation functions for vertex operators with negative integer exponentials of a periodic Liouville field, and derive the general case by continuing them as distributions. The path-integral based conjectures of Dorn and Otto prove to be conditionally valid only. We formulate integral representations for the generic vertex operators and indicate structures which are related to the Liouville S-matrix.
