Abstract
In their paper on the Szegö map, Knapp and WaJlach [KW] remarked that in the case of those discrete series representations of SU(2, 1) which occur as the subquotient of three principal series representations, their methods provided only two of these. That is, the Szegö map built from the highest weight vector misses some occurrences of discrete series represen- · tations as quotients. In this note we use the extension of Szegö maps due to Gilbert, Stanton, Kunze, and Tomas [GKST] to investigate these further cases.
