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…

Eigenspaces of Newforms with Nontrivial Character

Markos Karameris

Let $S_{k} (Γ_{0} (N), χ)$ denote the space of holomorphic cuspforms with Dirichlet character $χ$ and modular subgroup $Γ_{0} (N)$ . We will characterize the space of newforms $S_{k}^{new}(…
