We examine “partition zeta functions” analogous to the Riemann zeta function but summed over subsets of integer partitions. We prove an explicit formula for a family of partition zeta functions already shown to have nice properties — those summed over partitions of fixed length — which yields complete information about analytic continuation, poles and trivial roots of the zeta functions in the family. Then we present a combinatorial proof of the explicit formula, which shows it to be a zeta function analog of MacMahon’s partial fraction decomposition of the generating function for partitions of fixed length.

分区zeta函数的分析与组合

我们检查类似于黎曼 zeta 函数的“分区 zeta 函数”,但对整数分区的子集求和。我们证明了一个已证明具有良好性质的分区 zeta 函数族的显式公式——那些对固定长度的分区求和的函数——它产生了关于该族 zeta 函数的解析延拓、极点和平凡根的完整信息。然后我们给出了显式公式的组合证明,表明它是 MacMahon 对固定长度分区的生成函数的部分分数分解的 zeta 函数模拟。
