Abstract

We propose an algebraic description of (untwisted) D-branes on compact group manifolds using quantum algebras related to $U_q(\mg)$. It reproduces the known characteristics of stable branes in the WZW models, in particular their configurations in , energies as well as the set of harmonics. Both generic and degenerate branes are covered.
