Classifying algebras for boundary conditions and traces on spaces of conformal blocks
C. Schweigert, J. Fuchs
The boundary conditions of a non-trivial string background are classified. To this end we need traces on various spaces of conformal blocks, for which generalizations of the Verlin…

D-brane conformal field theory
J. Fuchs, C. Schweigert
We outline the structure of boundary conditions in conformal field theory. A boundary condition is specified by a consistent collection of reflection coefficients for bulk fields o…
