p-adic域上一般线性群通有表示的区别和Asai $L$ -函数

Distinction and Asai $L$-functions for generic representations of general linear groups over p-adic fields

Nadir Matringe

摘要:

设$K/F$是$p$ -adic域的二次扩张,$n$是正整数.称群$GL(n,K)$的光滑不可约表示是可区分的,如果它在其空间上允许非零的$GL(n,F)$ -不变线性形式。在目前的工作中,我们分类群$GL(n,K)$的一般区别表示的诱导准平方可积表示。因此,Rankin-Selberg型Asai $L$ -函数的类属表示和Asai $L$ -函数的朗兰兹参数之间的预期相等性是真实的。

英文摘要:

Let $K/F$ be a quadratic extension of $p$-adic fields, and $n$ a positive integer. A smooth irreducible representation of the group $GL(n,K)$ is said to be distinguished, if it admits on its space a nonzero $GL(n,F)$-invariant linear form. In the present work, we classify genric distinguished representations of the group $GL(n,K)$ in terms of inducing quasi-square-integrable representations. This has as a consequence the truth of the expected equality between the Rankin-Selberg type Asai $L$-function of a generic representation, and the Asai $L$-function of its Langlands parameter.
