5次幂上Ω SPT同余族的单变量证明

A Single-Variable Proof of the Omega SPT Congruence Family Over Powers of 5

Nicolas Allen Smoot

摘要:

在2018年,Liuquan Wang和Yifan Yang证明了对应于三阶模拟θ函数$ω(q)$的最小部分函数的无穷族同余的存在性。他们的证明采取了需要20个初始关系的归纳法的形式,并利用了同构于自由秩2 $\mathbb{Z}[X]$ -模的模函数空间。这种证明策略最初是由Paule和Radu开发的,用于研究亏格为1的模曲线的同余族。我们表明,王和杨的家庭的同余,这是与一个属0模曲线,可以证明使用单变量的方法,通过环的模函数同构的本地化$\mathbb{Z}[X]$。据我们所知,这是第一次,这样的代数结构已被应用到理论的划分同余。我们的归纳法更复杂,并且依赖于表现出有点不规则的5进增长的函数序列。然而,证明最终取决于只有10个初始关系的直接验证,并且类似于Ramanujan和Watson的经典方法。

英文摘要:

In 2018 Liuquan Wang and Yifan Yang proved the existence of an infinite family of congruences for the smallest parts function corresponding to the third order mock theta function $ω(q)$. Their proof took the form of an induction requiring 20 initial relations, and utilized a space of modular functions isomorphic to a free rank 2 $\mathbb{Z}[X]$-module. This proof strategy was originally developed by Paule and Radu to study families of congruences associated with modular curves of genus 1. We show that Wang and Yang's family of congruences, which is associated with a genus 0 modular curve, can be proved using a single-variable approach, via a ring of modular functions isomorphic to a localization of $\mathbb{Z}[X]$. To our knowledge, this is the first time that such an algebraic structure has been applied to the theory of partition congruences. Our induction is more complicated, and relies on sequences of functions which exhibit a somewhat irregular 5-adic growth. However, the proof ultimately rests upon the direct verification of only 10 initial relations, and is similar to the classical methods of Ramanujan and Watson.
