On invariants of discrete series representations of classical p-adic groups

To an irreducible square integrable representation ?? of a classical p-adic group, M?glin has attached invariants Jord(??), ?? _cusp and ${\epsilon_\pi}$ . These triples classify square integrable representations modulo cuspidal data (assuming a natural hypothesis). The definition of these invariants in M?glin (J Eur Math Soc 4(2):143?C200, 2002) is rather simple??in terms of induced representations, except at one case when a coherent normalization of standard intertwining operators is required. In this paper we show how one can define this case also in terms of induced representations.
