艾森斯坦级数、$p$进模函数与过收敛,II

Eisenstein series, $p$-adic modular functions, and overconvergence, II

Ian Kiming, Nadim Rustom

AI总结:

本研究延续同题前期工作,用统一方法证明了一类由归一化艾森斯坦级数与$p$进Frobenius算子构造的模函数的显式过收敛速率,拓展至素数2、3并改进了已有结果,还优化了$p\neq5$情形的相关结论。

摘要:

设$p$为素数。延续并拓展我们此前同标题的论文,我们证明了形如$\frac{E_k^{\text{*}}}{V(E_k^{\text{*}})}$的模函数的显式过收敛速率,其中$E_k^{\text{*}}$是$\text{Γ}_0(p)$上的经典归一化艾森斯坦级数,$V$为$p$进Frobenius算子。我们特别将此前的研究拓展至素数2和3。对于这些素数,我们的主定理在一定程度上改进了Emerton、Buzzard与Kilford以及Roe的早期结果,并从我们的视角对这些早期结果进行了详细讨论。我们还对论文中素数$p\neq5$的相关内容做了一些改进。除了取得这些改进外,我们的主要目的还在于证明所有这些结果都可通过统一方法得到,即论证的核心要点对所有素数均一致。我们通过若干数值示例对结果进行了说明。

英文摘要:

Let $p$ be a prime number. Continuing and extending our previous paper with the same title, we prove explicit rates of overconvergence for modular functions of the form $\frac{E_k^{\ast}}{V(E_k^{\ast})}$ where $E_k^{\ast}$ is a classical, normalized Eisenstein series on $Γ_0(p)$ and $V$ the $p$-adic Frobenius operator. In particular, we extend our previous paper to the primes $2$ and $3$. For these primes our main theorem improves somewhat upon earlier results by Emerton, Buzzard and Kilford, and Roe. We include a detailed discussion of those earlier results as seen from our perspective. We also give some improvements to our earlier paper for primes $p\ge 5$. Apart from establishing these improvements, our main purpose here is also to show that all of these results can be obtained by a uniform method, i.e., a method where the main points in the argumentation is the same for all primes. We illustrate the results by some numerical examples.
