D-branes in N=2 coset models and twisted equivariant K-theory

Abstract

The charges of D-branes in Kazama-Suzuki coset models are analyzed. We provide the calculation of the corresponding twisted equivariant K-theory, and in the case of Grassmannian cosets, su(n+1)/u(n), compare this to the charge lattices that are derived from boundary conformal field theory.
