整数划分中Hook长度的分布

Distributions of Hook lengths in integer partitions

Michael Griffin, Ken Ono, Wei-Lun Tsai

摘要:

受钩长在数学中扮演的许多角色的启发,我们研究了$n$的分区中$t$ -钩数的分布。我们证明了极限分布是正态分布,其均值为$μ_t(n)\sim \frac{\sqrt{6n}}π-\frac{t}{2}$,方差为$σ_t^2(n)\sim \frac{(π^2-6)\sqrt{6n}}{2π^3}.$。此外,我们还证明了在$n$的划分中,为固定$t\geq 4$的倍数的钩长数的分布收敛于一个带参数$k=(t-1)/2$和尺度为$θ=\sqrt{2/(t-1)}.$的移位Γ分布

英文摘要:

Motivated by the many roles that hook lengths play in mathematics, we study the distribution of the number of $t$-hooks in the partitions of $n$. We prove that the limiting distribution is normal with mean $μ_t(n)\sim \frac{\sqrt{6n}}π-\frac{t}{2}$ and variance $σ_t^2(n)\sim \frac{(π^2-6)\sqrt{6n}}{2π^3}.$ Furthermore, we prove that the distribution of the number of hook lengths that are multiples of a fixed $t\geq 4$ in partitions of $n$ converge to a shifted Gamma distribution with parameter $k=(t-1)/2$ and scale $θ=\sqrt{2/(t-1)}.$
