The exponential generating function of the number of standard Young tableaux of size n (or the number of involutions of n letters) is known to be , which coincides with the moment generating function of normal distribution . We apply Laplace's method to the moment integral to derive a new asymptotic formula of which is better than the known result. Meanwhile, by using of Can and Joyce's result in 2012, the number of skew product-type standard Young tableaux of size n is derived to be the n-th moment of normal distribution , where τ is geometric random variable. The generating function and the asymptotic formula of are obtained.

数的指数生成函数 已知大小为n(或n 个字母的对合次数)的标准 Young tableaux 为,与正态分布的矩生成函数一致 . 我们将拉普拉斯方法应用于矩积分以推导出新的渐近公式这比已知的结果要好。同时,利用 Can 和 Joyce 在 2012 年的结果,偏斜产品类型标准的大小为n 的Young tableaux导出为正态分布的第n个矩,其中τ是几何随机变量。的生成函数和渐近公式 获得。
