Riemann hypotheses

Must... start... writing... regularly, this is just a quick update about a talk I gave recently to try and ease myself into the swing of things.

I recently prepared a talk for the Warwick maths society on some analogues of the Riemann zeta function and associated statements about them that resemble the Riemann hypothesis. The talk was called "Riemann hypotheses", and there are some slides here.
It was a lot of fun to prepare and even though I only had time to discuss the Riemann, Ihara and Dedekind zeta functions in the end I think my message of "zeta functions are cool and varied objects that are fun to play with" came across at least a little bit.
