对任意正整数n,著名的F.Smarandache LCM函数SL(n)定义为最小的正整数k,使得n|[1,2,…,k],其中[1,2,…,k]表示1,2,…,k的最小公倍数.利用初等方法研究一类包含F.Smarandache LCM函数与除数函数σα(n)的混合均值,给出一个较强的渐近公式.
For any positive integer n,the famous F.Smarandache LCM function SL(n) is defined as the smallest positive integer k such that n|[1,2,…,k],where [1,2,…,k] denotes the least common multiple of 1,2,…,k.The main purpose of this paper is using the elementary methods to study a hybird mean value problem involving the F.Smarandache LCM function and the divisor function,and give a sharper asympto-tic formula for it.
