与$r$阶因子有关的函数

Functions concerned with divisors of order $r$

Andrew V. Lelechenko

摘要:

N. Minculete引入了$r$阶约数的概念:整数$d=p_1^{b_1}\cdots p_k^{b_k} $称为$n=p_1^{a_1}\cdots p_k^{a_k}$的$r$阶约数,如果$d \mid n$和$b_j\in\{r, a_j\}$用于$j=1,\ldots,k$。可以考虑相应的除数函数$τ^{(r)}$和除数和函数$σ^{(r)}$。本文研究了$\sum_{n\le x} τ^{(r)}(n)$和$\sum_{n\le x} σ^{(r)}(n)$的渐近行为.在Riemann假设下,我们也给出了条件估计。

英文摘要:

N. Minculete has introduced a concept of divisors of order $r$: integer $d=p_1^{b_1}\cdots p_k^{b_k} $ is called a divisor of order $r$ of $n=p_1^{a_1}\cdots p_k^{a_k}$ if $d \mid n$ and $b_j\in\{r, a_j\}$ for $j=1,\ldots,k$. One can consider respective divisor function $τ^{(r)}$ and sum-of-divisors function $σ^{(r)}$. In the present paper we investigate the asymptotic behaviour of $\sum_{n\le x} τ^{(r)}(n)$ and $\sum_{n\le x} σ^{(r)}(n)$. We also provide conditional estimates under Riemann hypothesis.
