AI中文摘要:

在任何特征为零的局部域上,我们发展了Jacquet-Shalika积分的局部理论,该积分最初由Jacquet和Shalika引入,用于研究GL_m的外平方局部L-因子。特别地,至少在阿基米德情形下,我们建立了匹配Artin局部ε-因子的完整函数方程。论证的核心是一种新的比较策略,用于对比Jacquet-Shalika积分与Shalika子群相关的开轨道积分。

英文摘要:

Over any local field of characteristic zero, we develop a local theory of Jacquet-Shalika integrals that were originally introduced by Jacquet and Shalika to study exterior square local $L$-factors for $GL_m$. In particular, at least in the archimedean case, we establish a complete functional equation matching Artin local $\varepsilon$-factors. Central to the argument is a novel comparison strategy between Jacquet-Shalika integrals and open-orbit integrals associated to the Shalika subgroup.
