Abstract
Let k, l be non-negative integers and \(\zeta ^{(k)}(s)\) denote the kth derivative of the Riemann zeta function \(\zeta (s).\) Further let \(d_{(k,l)}(n)\) be the nth coefficient of the Dirichlet series \(\zeta ^{(k)}(s)\zeta ^{(l)}(s)=\sum _{n=1}^{\infty }\frac{d_{(k,l)}(n)}{n^{s}}\) for \(\mathfrak {R}s>1,\) and \(\Delta _{(k,l)}(x)\) be the error term of \(\sum _{n\le x}d_{(k,l)}(n).\) In this paper, we will study some properties of \(\Delta _{(k,l)}(x)\), including its “truncated Voronoï formula” , the mean square formula and the higher-power moments.
