Pseudo-dual pairs and branching of Discrete Series

Bent Ørsted, Jorge A. Vargas

For a semisimple Lie group , we study Discrete Series representations with admissible branching to a symmetric subgroup . This is done using a canonical associated symmetric…

Some branching laws for symmetric spaces

Bent Orsted, Birgit Speh

In this paper we consider the unitary symmetric spaces of the form X=U(p,q)/U(1)U(p,q-1) and their discrete series representations. Inspired by the work of A.Venkatesh and Y.Sekell…

Askey-Wilson Polynomials and Branching Laws

Allen Back, Bent Orsted, Siddhartha Sahi +1

Connection coefficient formulas for special functions describe change of basis matrices under a parameter change, for bases formed by the special functions. Such formulas are relat…

Generalized Laguerre functions and Whittaker vectors for holomorphic discrete series

Jan Frahm, Gestur Ólafsson, Bent Ørsted

We study degenerate Whittaker vectors in scalar type holomorphic discrete series representations of tube type Hermitian Lie groups and their analytic continuation. In four differen…

Classification of -type formulas for the Heisenberg ultrahyperbolic operator for and tridiagonal determinants for local Heun functions

Toshihisa Kubo, Bent Ørsted

The -type formulas of the space of -finite solutions to the Heisenberg ultrahyperbolic equation for the non-linear group are cla…

Branching laws for discrete series of some affine symmetric spaces

Bent Orsted, Birgit Speh

In this paper we study branching laws for certain unitary representations. This is done on the smooth vectors via a version of the {\it period integrals}, studied in number theory,…
