# Irrationality proofs for zeta values, moduli spaces and dinner parties

@article{Brown2014IrrationalityPF, title={Irrationality proofs for zeta values, moduli spaces and dinner parties}, author={Francis Brown}, journal={arXiv: Number Theory}, year={2014} }

A simple geometric construction on the moduli spaces $\mathcal{M}_{0,n}$ of curves of genus $0$ with $n$ ordered marked points is described which gives a common framework for many irrationality proofs for zeta values. This construction yields Ap\'ery's approximations to $\zeta(2)$ and $\zeta(3)$, and for larger $n$, an infinite family of small linear forms in multiple zeta values with an interesting algebraic structure. It also contains a generalisation of the linear forms used by Ball and… Expand
