In this paper, we establish the following two identities involving the Gamma<br />
function and Bernoulli polynomials, namely $$\sum_{k\leq x}\frac{1}{k^s}<br /> \sum_{j=1}^{k^s}\log\Gamma\left(\frac{j}{k^s}\right)<br /> \sum_{\substack{d|k \\ d^{s}|j } }f*\mu(d) \quad {\rm and } \quad \sum_{k\leq<br /> x}\frac{1}{k^s}\sum_{j=0}^{k^{s}-1}<br /> B_{m}\sum_{\substack{d|k \\ d^{s}|j } } f*\mu(d)$$ with any fixed integer $s&gt;<br /> 1$ and any arithmetical function $f$. We give asymptotic formulas for them with<br />
various multiplicative functions $f$. We also consider several formulas of<br />
Dirichlet series associated with the above identities. This paper is a<br />
continuation of an earlier work of the authors.
