Using the realization of a discrete series A(\*) of a semi-simple symmetric space GÂH as a space of boundary values in the dual space G d ÂK d , we construct an explicit embedding of A(\*) in a principal series Ind and & uses the properties of what we call a ``fundamental system of roots.'' 2001 Ac

✦ Synopsis
It is well known that, on R n ; every smooth function annihilated by a finite codimensional ideal in the algebra of constant coefficient differential operators, is a linear combination of polynomial exponential functions, PðxÞe lðxÞ ; l 2 HomðR n ; CÞ: Furthermore, the polynomial functions are obtained by applying to the exponential functions e lðxÞ some constant coefficient differential operator in the parameter l: We generalize this fact to the reductive symmetric spaces' case, the role of the exponential functions being taken by the Eisenstein integrals.
