Hecke Subalgebras and Local Newforms for the Metaplectic Double Cover of $SL_{2} (Q_{p})$

Ehud Moshe Baruch, Markos Karameris, Soma Purkait

Let $p$ be an odd prime, and let $SL_{2} (Z_{p})$ and $K_{0} (p^{n})$ denote the inverse images of $SL_{2} (Z_{p})$ and the congruence su…

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…

Strong contraction, the mirabolic group and the Kirillov conjecture

Eyal M. Subag, Ehud Moshe Baruch

We lift any (infinitesimal) unitary irreducible representation of $G L_{n} (R)$ to a family of representations that strongly contracts to a certain type of (infinitesimal) uni…

Newforms of half-integral weight: the minus space of S_{k+1/2}(Γ_0(8M))

Ehud Moshe Baruch, Soma Purkait

We compute generators and relations for a certain $2$ -adic Hecke algebra of level $8$ associated with the double cover of $SL_{2}$ and a $2$ -adic Hecke algebra of level $4$ …
