T. Branson et al., SPECTRUM GENERATING OPERATORS AND INTERTWINING-OPERATORS FOR REPRESENTATIONS INDUCED FROM A MAXIMAL PARABOLIC SUBGROUP, Journal of functional analysis, 135(1), 1996, pp. 163-205
We present a new method of calculating intertwining operators between
principal series representations of semisimple Lie groups G. Working i
n the compact realization we find the eigenvalues of the operators on
the K-types, and give several examples. Among the advantages of our me
thod is its applicability to bundle-valued cases. (C) 1996 Academic Pr
