An algorithm for twisted fusion rules
T. Quella, I. Runkel, C. Schweigert
We present an algorithm for an efficient calculation of the fusion rules of twisted representations of untwisted affine Lie algebras. These fusion rules appear in WZW orbifold theo…

Lie algebra automorphisms in conformal field theory
J. Fuchs, C. Schweigert
The role of automorphisms of infinite-dimensional Lie algebras in conformal field theory is examined. Two main types of applications are discussed; they are related to the enhancem…

D-brane conformal field theory and bundles of conformal blocks
J. Fuchs, C. Schweigert
Conformal blocks form a system of vector bundles over the moduli space of complex curves with marked points. We discuss various aspects of these bundles. In particular, we present…
