Flat Connection, Conformal Field Theory and Quantum Group
Recently many people1 are discussing general framework of rational conformai field theories (RCFT). There, one of the important concept is a connection matrix of conformai blocks. Once connection matrices are given for the conformai blocks, which are made from chiral vertex operators of a given chiral algebra by sandwitch-ing them with SL 2 invariant vacuum, then we can construct the physical correlation functions invariant under monodromy transformations and determine operator product expansion coefficients in principle.
