## Math Club - Francesco Cellarosi (Queen's University)

### Thursday, April 4th, 2019

**Time:** 5:30 - 6:30 p.m ** Place:** Jeffery Hall 118

**Speaker:** Francesco Cellarosi (Queen's University)

**Title:** The irrationality of $\zeta(3)$.

**Abstract:** This talk will discuss the famous theorem by R. Apéry who showed in 1978 that $\zeta(3)$ is irrational.

We will see a proof of this fact, due to F. Beuker in 1979, which only uses calculus.
