Event description: 

Let G be a semisimple Lie group H be a closed unimodular connected subgroup,and V be the Hilbert space of square integrable functions on the homogeneous space G/HI will explain an easy-to-check necessary and sufficient condition under which the unitary representation of G in V is tempered.Joint work with T. Kobayashi.
