I'm working through an example problem wherein this bound is used:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\left| \log \left( 1-\frac{1}{L^s}\right) \right| \leq L^{-\sigma},[/tex]

where [tex]s:=\sigma +it[/tex] and it is known that [tex]\sigma >1.[/tex] How do I prove this? Should I assume the principle brach is taken?
