摘要:

朗兰兹提出的超越内窥法旨在通过分析迹公式建立泛函性原理。邓和埃斯皮诺萨通过从椭圆正则部分分离平凡表示的贡献推进了\(\mathrm{GL}_3(\mathbb{Q})\)的这个计划。他们的工作依赖于与三次序相关的\(L\)函数的一个推测性分解公式,该公式给出了完备\(L\)函数的函数方程。本文为三次数域中的每个戈伦斯坦序提供了这个函数方程的无条件证明。因此,他们对\(\mathrm{GL}_3(\mathbb{Q})\)平凡表示的分离变得完全无条件。

英文摘要:

The Beyond Endoscopy strategy, proposed by Langlands, aims to establish the principle of functoriality by analyzing the trace formula. Recently, Deng and Espinosa advanced this program for $\mathrm{GL}_3(\mathbb{Q})$ by isolating the contribution of the trivial representation from the elliptic regular part. Their work relies on a conjectural factorization formula for the $L$-function associated with a cubic order, which yields the functional equation for the completed $L$-function. In this paper, we provide an unconditional proof of this functional equation for every Gorenstein order in a cubic number field. As a consequence, their isolation of the trivial representation for $\mathrm{GL}_3(\mathbb{Q})$ becomes fully unconditional.
