If P = MN is a parabolic subgroup of G and V a smooth representation of G, its Jacquet module is its maximal N -trivial quotient VN . This is a smooth representation of M = P/N , and if V is anâ€¦ (More)

If G is a split reductive group and B a Borel subgroup then G is the disjoint union of the BwB as w ranges over the Weyl group of a maximal torus in B. The closure of BwB is the union of certainâ€¦ (More)
