$\mathrm{GL}_n$尖点表示的外平方伽玛因子:有限域类似物和零级表示

Exterior square gamma factors for cuspidal representations of $\mathrm{GL}_n$: finite field analogs and level zero representations

Rongqing Ye, Elad Zelingher

摘要:

我们遵循Jacquet-Shalika,Matringe和Cogdell-Matringe定义外部平方伽玛因子的$\mathrm{GL}_n(\mathbb{F}_q)$的不可约尖点表示。这些外部平方伽马因子用贝塞尔函数表示,或者用与尖点表示相关联的正则字符表示。我们还涉及到我们的外部平方伽马因子在有限域的局部域通过零级表示。

英文摘要:

We follow Jacquet-Shalika, Matringe and Cogdell-Matringe to define exterior square gamma factors for irreducible cuspidal representations of $\mathrm{GL}_n(\mathbb{F}_q)$. These exterior square gamma factors are expressed in terms of Bessel functions, or in terms of the regular characters associated with the cuspidal representations. We also relate our exterior square gamma factors over finite fields to those over local fields through level zero representations.
