In this paper, we show that the numbers of t -stack sortable n -permutations with k − 1 descents satisfy central and local limit theorems for t = 1, 2, n − 1 and n − 2. This result, in particular, gives an affirmative answer to Shapiro's question about the asymptotic normality of the Narayana numbers.

t-stack 可排序排列中的渐近正态性
在本文中,我们证明了吨 - 堆栈可排序n -排列与ķ − 1 下降满足中心和局部极限定理吨 = 1, 2,n − 1 和n − 2. 这个结果尤其对夏皮罗关于纳拉亚纳数的渐近正态性的问题给出了肯定的回答。
