Pairs A ⊂ B of local quantum field theories are studied, where A is a chiral conformal quantum field theory and B is a local extension, either chiral or two-dimensional. The local correlation functions of fields from B have an expansion with respect to A into conformal blocks, which are nonlocal in general. Two methods of computing characteristic invariant… (More)
