Abstract
We find some exact solutions of the Knizhnik-Zamolodchikov equation for the four-point correlation functions that occur in the SL(2, R) WZNW model, Th ey exhibit logarithmic behaviour in both the Kac-Moody and Virasoro parts. We discuss their implication for the operator product expansion. We also ob serve the appearance of several symmetries of the correlation functions. (C ) 2001 Elsevier Science B.V.
