On the Jacquet functor of Symplectic groups

Let $\text{F}$ be a non-Archimedean local field.~Consider ${\text{G}}_n:={\text{Sp}}_{2n}(\text{F})$ and let $\text{M}:={\text{GL}}_l\times {\text{G}}_{n-l}$ be a maximal Levi subgroup of ${\text{G}}_n$.~This paper undertakes the computation of the Jacquet module of representations of ${\text{G}}_n$ with respect to the maximal Levi subgroup, belonging to a particular class. Finally, we conclude that for a subclass of representations of ${\text{G}}_n,$ multiplicity of the Jacquet module does not exceed 2.
