Abstract
We consider the inclusion of brane charges in 5-d AdS superalgebras that contain the maximal central extension of the super-Poincare' algebra on the AdS boundary. For theories with N supersymmetries on the boundary, the maximal extension is OSp(1/8N), which contains the group Sp(8N,R) as extension of the conformal group. An "intermediate" extension to U(2N,2N/1) is also presented. BPS conditions on boundary states are studied in some details.
