AI总结:

本文研究超分割中上划线部分的奇偶和之差,定义OSOME(n)并求得生成函数闭式,利用q级数与模形式方法证明同余性质。

AI中文摘要:

最近,Garvan 和 Sarma 研究了超分割以及无重复奇数部分的分割中非上划线部分的和。在本文中,我们研究了上划线部分的相应统计量。我们将 $\mathrm{OSOME}(n)$ 定义为 $n$ 的超分割中所有奇数上划线部分之和减去所有偶数上划线部分之和。我们得到了其生成函数的闭式表达式,并利用初等 $q$-级数方法、半整数权模形式理论以及超分割函数的已知同余式,证明了同余性质。

英文摘要:

Recently, Garvan and Sarma studied sums of non-overlined parts in overpartitions and partitions without repeated odd parts. In this paper, we study the corresponding statistic for overlined parts. We define $\mathrm{OSOME}(n)$ as the sum of all odd overlined parts minus the sum of all even overlined parts in the overpartitions of $n$. We obtain a closed form for its generating function and use it to prove congruences by elementary $q$-series methods, the theory of half-integral weight modular forms, and known congruences for the overpartition function.
