Abstract
Let G be a connected, semisimple real Lie group with finite center, K a maximal compact subgroup of G. Assume rank G = rank K. Let be the Lie algebra of G, its complexification. If Gc is the simplyconnected complex analytic group corresponding to assume G is the real analytic subgroup of Gc corresponding to .

G always has discrete series representations. The characters of these representations are distributions on the group G, realizable as locally integrable functions. Formulas for these characters are known up to certain integer constants which have only been evaluated for a few special cases
