目的研究一个包含Smarandache函数S(n)及Smarandache LCM函数SL(n)的混合均值问题。方法利用初等及解析方法以及组合技巧。结果证明了在一个给定区间[1,x]上,满足S(n)≠SL(n)的正整数的个数与x相比,是一个高阶无穷小。给出了一个混合均值公式。结论函数S(n)与SL(n)的值几乎处处相等。
Aim To study a hybrid mean value problem involving the Smarandache function S(n) and the Smarandache LCM function SL(n).Methods Using the elementary and analytic methods,and some combinational skill.Results It was proved that in the interval ,n:S(n)≠SL(n)=O(x).Given an interesting hybrid mean value formula.Conclusion This shows that the value of S(n) is almost equal to SL(n).
