*Many odd zeta values are irrational*

### Abstract

Proving that a given number, like the value of Riemann's zeta function
\(\zeta(s)\) at an integer \(s\ge2\), is irrational may be challenging.
Especially, if \(s\) is an odd integer. In my talk I outline some very recent
(from 2018!) developments of the topic, some difficulties involved and some
generalisations followed. Hopefully, this is for general mathematics audience,
prior knowledge about how to prove that a number is irrational is not
required.
