The regularization of Dotsenko–Fateev integrals
The regularization of Dotsenko–Fateev integrals
Abstract We discuss the regularization of certain hypergeometric integrals appearing in 2D CFT, a step needed in the construction of the BPZ minimal models via the Coulomb gas formalism. The method is a generalization of Pochhammer’s regularization of the Euler Beta-function. The constructions of the relevant homology classes are inspired …
