In this paper, we present two explicit expressions of the moments of the Kesten distribution in terms of Catalan's triangles and Shapiro's Catalan triangles , respectively. As a corollary, we provide a generalization of the identity, due to Eplett, between the Catalan number and the triangles . As an application, we obtain an asymptotic formula on as k tends to infinity.

关于 Kesten 分布矩的注释
在本文中,我们提出了矩的两个显式表达式 以加泰罗尼亚三角形表示的 Kesten 分布 和夏皮罗的加泰罗尼亚三角形 , 分别。作为推论,由于 Eplett,我们提供了加泰罗尼亚数之间的恒等式的概括 和三角形 . 作为应用,我们得到了一个渐近公式因为k趋于无穷大。
