Speh表示是相对离散的
Speh representations are relatively discrete
摘要:
设$F$是特征为零且剩余特征为奇的$p$ -adic域。令$\mathbf{Sp}_{2n}(F)$表示定义在$F$上的辛群,其中$n\geq 2$。我们证明了Speh表示$\mathcal{U}(δ,2)$,其中$δ$是$\mathbf{GL}_n(F)$的离散级数表示,位于$p$ -adic对称空间$\mathbf{Sp}_{2n}(F) \backslash \mathbf{GL}_{2n}(F)$的离散谱中.
英文摘要:
Let $F$ be a $p$-adic field of characteristic zero and odd residual characteristic. Let $\mathbf{Sp}_{2n}(F)$ denote the symplectic group defined over $F$, where $n\geq 2$. We prove that the Speh representations $\mathcal{U}(δ,2)$, where $δ$ is a discrete series representation of $\mathbf{GL}_n(F)$, lie in the discrete spectrum of the $p$-adic symmetric space $\mathbf{Sp}_{2n}(F) \backslash \mathbf{GL}_{2n}(F)$.
