D-branes in the Euclidean AdS3 and T-duality

We show that D-branes in the Euclidean AdS3 can be naturally associated to the maximally isotropic subgroups of the Lu-Weinstein double of SU(2). This picture makes very transparent the residual loop group symme- try of the D-brane congurations and gives also immediately theD-branes shapes and the sigma-model boundary conditions in the de Sitter T-dual of the SL(2,C)=SU(2) WZW model.
