摘    要:设n是正整数,ur(n)表示不小于n的最小r角形数部分数列,vr(n)表示大于n 的最大r角形数部分数列,a(n)=n-ur(n),b(n)=vr(n)-n.研究了2个Smarandache函数S(n)和SL(n)分别与a(n)和b(n)的混合均值,并用解析方法得到几个较强的渐近公式.

关 键 词:Smarandache  函数  r角形数  均值  渐近公式

Abstract:Let n be a positive integer,ur(n) be the smallest r angular number greater than or equal to n,and vr(n) be the largest r angular number less than or equal to n.Let:a(n)=n-ur(n),b(n)=vr(n)-n.The hybrid mean value formulas involving two Smarandache functions S(n) and SL(n) with a(n) and b(n) are studied,and several sharper asymptotic formulas are given by using the analytic methods.
