Analytic continuations of 3-point functions of the conformal field theory

It is shown that the general 3-point function 〈ΦcΦbΦa〉〈ΦcΦbΦa〉, with continuous values of charges a,b,ca,b,c of a statistical model operators, and the 3-point function of the Liouville model, could all be obtained by successive analytical continuations starting from the 3-point function of the minimal model.
