一个p进算术内积公式

A $p$-adic arithmetic inner product formula

Daniel Disegni, Yifeng Liu

AI总结:

本文构造了偶秩拟分裂酉群上自守表示的分圆p进L-函数,证明其在平凡特征处消没阶为1时Selmer群秩至少为1,并利用酉Shimura簇上的特殊圈构造Selmer theta提升,建立了p进高度与p进L-函数导数之间的精确公式,即算术内积公式的p进类比。

摘要:

固定一个素数$p$,设$E/F$是数域的CM扩张,其中$p$相对分裂。设$π$是关于$E/F$的偶秩拟分裂酉群的自守表示,使得$π$在$p$上相对于Siegel抛物子群是普通的。我们构造了$π$的分圆$p$进$L$-函数,并证明在某些条件下,如果它在平凡特征处的消没阶为$1$,则与$π$相关联的$E$的Galois表示的Selmer群的秩至少为$1$。此外,在某个模性假设下,我们利用酉Shimura簇上的特殊圈构造了Selmer群中一些被称为Selmer theta提升的显式元素;并且我们证明了一个精确公式,将它们的$p$进高度与$p$进$L$-函数的导数联系起来。与Perrin-Riou的Gross--Zagier公式的$p$进类比相平行,我们的公式是Chao Li和第二作者最近建立的算术内积公式的$p$进类比。

英文摘要:

Fix a prime number $p$ and let $E/F$ be a CM extension of number fields in which $p$ splits relatively. Let $π$ be an automorphic representation of a quasi-split unitary group of even rank with respect to $E/F$ such that $π$ is ordinary above $p$ with respect to the Siegel parabolic subgroup. We construct the cyclotomic $p$-adic $L$-function of $π$, and show, under certain conditions, that if its order of vanishing at the trivial character is $1$, then the rank of the Selmer group of the Galois representation of $E$ associated with $π$ is at least $1$. Furthermore, under a certain modularity hypothesis, we use special cycles on unitary Shimura varieties to construct some explicit elements in the Selmer group called Selmer theta lifts; and we prove a precise formula relating their $p$-adic heights to the derivative of the $p$-adic $L$-function. In parallel to Perrin-Riou's $p$-adic analogue of the Gross--Zagier formula, our formula is the $p$-adic analogue of the arithmetic inner product formula recently established by Chao~Li and the second author.
