Abstract: (Elsevier)

Some aspects of the geometry on the moduli space of CFT are discussed. The two-point function of the moduli is the metric on the space, the connection appears as a contact term and the four-point function determines the Riemann tensor. The relation between the OPE of moduli and the curvature is examined, and a condition for homogeneity is obtained.
