正曲柄矩和正秩矩的渐近不等式

Asymptotic inequalities for positive crank and rank moments

Kathrin Bringmann, Karl Mahlburg

摘要:

Andrews、Chan和Kim最近引入了一个修正的曲柄矩和秩矩的定义,允许研究偶数和奇数矩。在本文中,我们证明了这些时刻在所有情况下的渐近行为,我们的主要结果表明,而这两个家庭的力矩函数是渐近相等的,曲柄时刻总是渐近大于秩矩。Andrews,Chan和Kim主要集中在一种情况下,并证明了更强的结果,即对于所有分区,第一曲柄矩严格大于第一秩矩,通过显示差值等于他们命名为ospt函数的分区上的组合统计量。因此,我们的主要结果也给出了ospt函数的渐近行为,我们进一步确定其模2的行为,通过将其奇偶性与Andrews spt函数联系起来。

英文摘要:

Andrews, Chan, and Kim recently introduced a modified definition of crank and rank moments for integer partitions that allows the study of both even and odd moments. In this paper, we prove the asymptotic behavior of these moments in all cases, and our main result states that while the two families of moment functions are asymptotically equal, the crank moments are always asymptotically larger than the rank moments. Andrews, Chan, and Kim primarily focused on one case, and proved the stronger result that the first crank moment is strictly larger than the first rank moment for all partitions by showing that the difference is equal to a combinatorial statistic on partitions that they named the ospt-function. Our main results therefore also give the asymptotic behavior of the ospt-function, and we further determine its behavior modulo 2 by relating its parity to Andrews spt-function.
