Spherical unitary dual of general linear group over non-archimedean local field (Q759832)

Let F be a local non-archimedean field. The set of all equivalence classes of irreducible spherical representations of GL(n,F) is described in the first part of the paper. In particular, it is shown that each irreducible spherical representation is parabolically induced by an unramified character. Bernstein's result on the irreducibility of the parabolically induced representations of GL(n,F) by irreducible unitary ones, and Ol'shanskij's construction of complementary series give directly a description of all equivalence classes of irreducible unitary spherical representations of GL(n,F).
