This paper has as its primary purpose a clear exposition of the idea in [21]
which we describe as transfer between real forms of a semi-simple Lie group over $\bb{C}$.
The basic point is that there are representations of one real form that can be more
easily understood in the context of another real from. An interesting example
is a minimal representation (that is annihilated by the Joseph ideal) of a split group over $\bb{R}$.
In the case when the complexi.cation admits a Hermitian symmetric real form,
minimal representations of that real form are part of the
"analytic continuation of the holomorphic discrete series"(cf.[5]) ...
