Twist-field representations of W-algebras, exact conformal blocks and character identities

Abstract We study the twist-field representations of W-algebras and generalize construction of the corresponding vertex operators to D- and B-series. It is shown, how the computation of characters of these representations leads to nontrivial identities involving lattice theta-functions. We also prop...
