Abstract
A complete proof of the no-ghost theorem for bosonic and fermionic string t heories on AdS(3), or the group manifold of SU(1, 1), is given. It is then shown that the restriction on the spin (in terms of the level) that is nece ssary to obtain a ghost-free spectrum corresponds to the stringy exclusion principle of Maldacena and Strominger.
