چکیده
We determine test vectors and explicit formulas for all Bessel models for those Iwahori-spherical representations of GSp4 over a p-adic field that have non-zero vectors fixed under the Siegel congruence subgroup.

Se p 20 09 Steinberg representation of GSp 4 : Bessel models and integral representation of L - functions
Abstract. We obtain explicit formulas for the test vector in the Bessel model and derive the criteria for existence and uniqueness for Bessel models for the unramified, quadratic twists of the Steinberg representation π of GSp 4 (F ), where F is a non-archimedean local field of characteristic zero. We also give precise criteria for the Iwahori spherical vector in π to be a test vector. We apply...
متن کاملOn Siegel modular forms of degree 2 with square-free level
In contrast to this situation, there is currently no satisfactory theory of local newforms for the group GSp(2, F ). As a consequence, there is no analogue of Atkin–Lehner theory for Siegel modular forms of degree 2. In this paper we shall present such a theory for the “square-free” case. In the local context this means that the representations in question are assumed to have nontrivial Iwahori...
متن کاملM ay 2 00 5 Whittaker and Bessel functors for G S p 4
The theory of Whittaker functors for GLn is an essential technical tools in Gaitsgory’s proof of the Vanishing Conjecture appearing in the geometric Langlands correspondence ([5]). We define Whittaker functors for GSp 4 and study their properties. These functors correspond to the maximal parabolic subgroup of GSp 4 , whose unipotent radical is not commutative. We also study similar functors cor...
متن کاملIwahori–spherical representations of GSp(4) and Siegel modular forms of degree 2 with square-free level
A theory of local old– and newforms for representations of GSp(4) over a p–adic field with Iwahori– invariant vectors is developed. The results are applied to Siegel modular forms of degree 2 with square-free level with respect to various congruence subgroups. Introduction For representations of GL(2) over a p–adic field F there is a well-known theory of local newforms due to Casselman, see [Ca...
متن کاملS ep 2 00 8 Bessel models for lowest weight representations of GSp ( 4 , R )
We prove uniqueness and give precise criteria for existence of split and non-split Bessel models for a class of lowest and highest weight representations of the groups GSp(4,R) and Sp(4,R) including all holomorphic and anti-holomorphic discrete series representations. Explicit formulas for the resulting Bessel functions are obtained by solving systems of differential equations. The formulas are...
