Parahoric Spherical Whittaker Functions

Markos Karameris

Let $F$ be a non-archimedean local field and let $K_{μ}$ be a standard parahoric subgroup of $G L_{n} (F)$ . We express the diagonal values of normalized parahoric Whittaker eigenfunction…

Iwahori Spherical Whittaker Functions for Steinberg Representations

Markos Karameris, Ehud Moshe Baruch

Let $G (F)$ be a split reductive group over a $p$ -adic field $F$ and let $(π_{S t}, V)$ be a (generalized) Steinberg representation of $G (F)$ . It is known that the space of Iwahori fi…

Whittaker functions for Steinberg representations of $G L (n)$ over a $p$ -adic field

Ehud Moshe Baruch, Markos Karameris

Let $G = G L_{n} (F)$ and let $(π_{S t}, V)$ be a (generalized) Steinberg representation of $G$ . It is well known that the space of Iwahori fixed vectors in $V$ is one dimensional. The I…
