关于含整部函数的一些求和

On some sums involving the integral part function

Kui Liu, Jie Wu, Zhishan Yang

摘要:

用$τ$ k(n)、$ω$(n)和$μ$ 2(n)分别表示n作为k个自然数的乘积的表示的数目、n的不同素因子的数目和无平方整数的特征函数。设[t]是实数t的整数部分。对f = $ω$,2 $ω$,$μ$ 2,$τ$ k,我们证明了nxfxn = xd 1 f(d)d(d + 1)+ O $ε$对于x $\rightarrow$ $\infty$,(x $θ$ f + $ε$),其中$θ$ $ω$ = 53 110,$θ$ 2 $ω$ = 9 19,$θ$ $μ$ 2 = 2 5,$θ$ $τ$ k = 5 k-1 10 k-1且$ε$ > 0是任意小的正数。这改进了Bordell{è}s的相应结果.

英文摘要:

Denote by $τ$ k (n), $ω$(n) and $μ$ 2 (n) the number of representations of n as product of k natural numbers, the number of distinct prime factors of n and the characteristic function of the square-free integers, respectively. Let [t] be the integral part of real number t. For f = $ω$, 2 $ω$ , $μ$ 2 , $τ$ k , we prove that n x f x n = x d 1 f (d) d(d + 1) + O $ε$ (x $θ$ f +$ε$) for x $\rightarrow$ $\infty$, where $θ$ $ω$ = 53 110 , $θ$ 2 $ω$ = 9 19 , $θ$ $μ$2 = 2 5 , $θ$ $τ$ k = 5k--1 10k--1 and $ε$ > 0 is an arbitrarily small positive number. These improve the corresponding results of Bordell{è}s.
