Bundles of chiral blocks and boundary conditions in CFT
arXiv:hep-th/0001005
Abstract
Various aspects of spaces of chiral blocks are discussed. In particular, conjectures about the dimensions of irreducible sub-bundles are reviewed and their relation to symmetry breaking conformal boundary conditions is outlined.
