Comments on D-branes on general group manifolds
Abstract
We investigate D-branes with maximal symmetry on general group manifolds in terms of boundary states and effective actions. We show that in large k limit boundary states with an suitable Wilson line form boundary states of the other types of D-branes, extending the known fact in SU(2) case. We also show that fluctuation mass spectrum around D-brane solutions of the effective action agrees with that of boundary CFT in large k limit.
