$(s,ms\pm1)$-核分区的算盘结构

Abaci structures of $(s,ms\pm1)$-core partitions

Rishi Nath, James A. Sellers

AI总结:

本文通过$ms$-abaci几何方法研究$(s,ms\pm1)$-核分区,给出了若干计数结果的新证明,计算了最大$(s,ms-1,ms+1)$-核分区权重,并用2-核分区枚举了自共轭核分区。

摘要:

我们开发了一种几何方法,通过相关的$ms$-abaci研究$(s,ms-1)$-核和$(s,ms+1)$-核分区。这一视角为H. Xiong和A. Straub(最初由T. Amdeberhan提出)关于具有不同部分的$(s,s+1)$和$(s,ms-1)$-核分区计数的结果提供了新证明,并对具有不同部分的$(s,ms+1)$-核进行了计数。此外,我们计算了具有最多部分的$(s,ms-1,ms+1)$-核分区的权重。最后,我们使用2-核分区来枚举具有不同部分的自共轭核分区。核心思想是,极大$(s,ms\pm1)$-核的$ms$-abaci可以优雅地从$(s,s\pm1)$-核的$s$-abaci构建而成。

英文摘要:

We develop a geometric approach to the study of $(s,ms-1)$-core and $(s,ms+1)$-core partitions through the associated $ms$-abaci. This perspective yields new proofs for results of H. Xiong and A. Straub (originally proposed by T. Amdeberhan) on the enumeration of $(s, s+1)$ and $(s,ms-1)$-core partitions with distinct parts. It also enumerates the $(s, ms+1)$-cores with distinct parts. Furthermore, we calculate the weight of the $(s, ms-1,ms+1)$-core partition with the largest number of parts. Finally we use 2-core partitions to enumerate self-conjugate core partitions with distinct parts. The central idea is that the $ms$-abaci of maximal $(s,ms\pm1)$-cores can be built up from $s$-abaci of $(s,s\pm 1)$-cores in an elegant way.
