摘    要:对任意正整数n,Pd(n)定义为n的所有正因子的乘积,gd(n)定义为n的所有小于n的正因子的乘积。若n=p1^a1p2^a2…px^as是n的标准分解式,算数函数Ω(n)=a1+a2+…+as。用解析的方法研究关于Smarandache序列Pd(n)、qd(n)与Q(n)的混合均值,并给出两个较好的渐近公式。

关 键 词:Smarandache序列Pd(n)  qd(n)  函数Ω(n)  混合均值  渐近公式

Abstract:For any positive integer n, Pd(n) denotes the product of all positive divisors of n, qd (n) denotes the product of all positive divisors which are less than n. n = p1^a1p2^a2…px^as is the standard factorization of n and arithmetic function is Ω(n) = a1+a2+…+as, The main purpose of the paper is to use the analytic methods to study the hybrid mean value problem involving those two sequences and function Ω(n) , and give two sharper asymptotic formulas.
Keywords:sequences Pd (n) and qd (n)  function Ω(n)  hybrid mean value  asymptotic formula
