Let \(k\geqslant 2\) be a fixed natural number and \(d_k(n)\) denote the number of ways n can be written as a product of k positive integers. We use \(\Delta _k(x)\) to denote the error term in the asymptotic formula of the summatory function of \(d_k(n).\) The aim of this paper is to study the hybrid moments of \(\Delta _2(x)\) and \(\Delta _3(x)\). The higher power moments of \(\Delta _2(x)\) are also studied.

在$$ \ Delta _2(x)$$Δ2(x)和$$ \ Delta _3(x)$$Δ3(x)的混合矩上

\(k \ geqslant 2 \)是一个固定的自然数,而\(d_k(n)\)表示n可以写为k个正整数的乘积的方式的数目。我们使用\(\ Delta _k(x)\)来表示\(d_k(n)。}的求和函数的渐近公式中的误差项本文的目的是研究\(\ Delta _2(x)\)\(\ Delta _3(x)\)。还研究了\(\ Delta _2(x)\)的较高功率矩。
