Mangoldt function

(Definition)

The Mangoldt function $\Lambda$ is defined by

$\begin{displaymath}\Lambda (n) = \begin{cases} \ln p, &\text{if $n=p^k$, where $... ...a natural number $\geq 1$}\ 0, &\text{otherwise} \end{cases} \end{displaymath}$

The Moebius Inversion Formula leads to the identity $\Lambda (n) = \sum_{d|n} \mu (n/d) \ln d = - \sum_{d|n} \mu (d) \ln d$ .
