D-Brane Charges in Gepner Models

High Energy Physics - Theory 2015-06-26 v3

Abstract

We construct Gepner models in terms of coset conformal field theories and compute their twisted equivariant K-theories. These classify the D-brane charges on the associated geometric backgrounds and therefore agree with the topological K-theories. We show this agreement for various cases, in particular the Fermat quintic.
