Let F be a non-Archimedean local field of characteristic zero. Let G = GL(2, F ) and $3\widetildeG = \widetilde{GL}(2,F)$ be the metaplectic group. Let τ be the standard involution on G . A well-known theorem of Gelfand and Kazhdan says that the standard involution takes any irreducible admissible representation of G to its contragredient. In such a case, we say that τ is a dualizing involution. In this paper, we make some modifications and adapt a topological argument of Tupan to the metaplectic group $\widetildeG$ and give an elementary proof that any lift of the standard involution to $\widetildeG$ ; is also a dualizing involution.

METAPLECTIC GL(2) à la TUPAN 的双重化
让F 是特征为零的非阿基米德局部场。让G = GL(2,F ) 和$3\widetildeG = \widetilde{GL}(2,F)$ 是元理组。让τ 成为标准对合G . Gelfand 和 Kazhdan 的一个著名定理说,标准对合取G 与其相反。在这种情况下,我们说τ 是对偶对合。在本文中,我们进行了一些修改,并将 Tupan 的拓扑论证适用于 metaplectic 群$\宽波浪号G$ 并给出一个基本证明,证明标准对合的任何提升$\宽波浪号G$ ; 也是一个二元对合。
