# Mangoldt

$\large \dfrac 1{\gamma} \sum\limits_{n=1}^{\infty} \frac{\Lambda(n)-1}{n}= \, ?$

Notations:

• $$\gamma$$ denotes the Euler–Mascheroni constant, $$\displaystyle\gamma = \lim_{n\to\infty} \left( - \ln(n) + \sum_{k=1}^n \dfrac1k \right) \approx 0.5772$$.

• $$\Lambda$$ denotes the Von Mangoldt function.
