Let X and Y be two
holomorphically induced representations for an irreducible Hermitian symmetric pair
(G,K) with integral highest weights. Then Hom(X,Y ) equals either C or zero. In
this article we give formulas for Hom(X,Y ) when the infinitesmial character of X
and Y is integral and either regular or semi-regular. One formula is given in terms of
the highest weight of X and the other in terms of the highest weight of
Y .
