P-adic L-functions for GL(3)

David Loeffler, Chris Williams

AI总结:

本文构造了GL(3)的p进L函数,证明了相关猜想,并首次给出了非自对偶表示的p进L函数构造方法。

摘要:

设Π是一个GL_3(Q_A)的正则代数自射影自射影表示(RACAR)。当Π对于最大标准抛物面体Levi因子GL_1×GL_2是p-近正则时,我们构造了Π的p进L函数。更具体地说,我们构造了一个附加于Π的有界测度L_p(Π)在Z_p^×上,并证明它插值了Π在左半临界带中的所有临界值L(Π×η,-j)在p处(对于变化的η和j)。这证明了Coates-Perrin-Riou和Panchishkin的猜想在这种情况下的正确性。我们还证明了在临界带的右半部分也有相应结果,假设对于另一个最大标准抛物面体的近正则性。我们的构造使用了球面品种的理论来构建一个“贝蒂欧拉系统”,即在GL_3的局部对称空间的贝蒂上同调中的一组规范兼容的类。我们工作在任意上同调重量中,允许在Levi因子上的任意p-分支,且不作自对偶假设。因此,我们给出了第一个对于GL_n(Q_A)的RACARs的p进L函数的构造,这些RACARs为“一般类型”(即不作为函子提升出现的),对于任何n>2。

英文摘要:

Let $Π$ be a regular algebraic cuspidal automorphic representation (RACAR) of $\mathrm{GL}_3(\mathbb{A}_{\mathbb{Q}})$. When $Π$ is $p$-nearly-ordinary for the maximal standard parabolic with Levi $\mathrm{GL}_1 \times \mathrm{GL}_2$, we construct a $p$-adic $L$-function for $Π$. More precisely, we construct a (single) bounded measure $L_p(Π)$ on $\mathbb{Z}_p^\times$ attached to $Π$, and show it interpolates all the critical values $L(Π\timesη,-j)$ at $p$ in the left-half of the critical strip for $Π$ (for varying $η$ and $j$). This proves conjectures of Coates-Perrin-Riou and Panchishkin in this case. We also prove a corresponding result in the right half of the critical strip, assuming near-ordinarity for the other maximal standard parabolic. Our construction uses the theory of spherical varieties to build a "Betti Euler system", a norm-compatible system of classes in the Betti cohomology of a locally symmetric space for $\mathrm{GL}_3$. We work in arbitrary cohomological weight, allow arbitrary ramification at $p$ along the Levi factor of the standard parabolic, and make no self-duality assumption. We thus give the first constructions of $p$-adic $L$-functions for RACARs of $\mathrm{GL}_n(\mathbb{A}_{\mathbb{Q}})$ of 'general type' (i.e., those that do not arise as functorial lifts) for any $n > 2$.
