Riemann says that the zeta function doesn't have zeros on the half plane [itex]\{z\in\mathbb{C}\;|\;\textrm{Re}(z)>1\}[/itex], because the sum(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\log(\zeta(z)) = \log\Big(\frac{1}{\underset{p\in\mathbb{P}}{\prod}\big(1 - \frac{1}{p^z}\big)}\Big) = -\sum_{p\in\mathbb{P}}\log\big(1 - \frac{1}{p^z}\big)

[/tex]

remains finite. Well, why does that sum remain finite? Doesn't look quite obvious to me.

hmhmh... what kind of set is the set

[tex]

\zeta(\{z\in\mathbb{C}\;|\;\textrm{Re}(z)>1\})\subset\mathbb{C}?

[/tex]

Does it fit in a domain of some logarithm, or does it wind around the origo?
