The moduli space of genus 2 Riemann surfaces
Algebra and Topology seminar, 15th October 2013


Abstract An exploration of this moduli space using only nineteenth century mathematics and a small computer. We shall discover the most bizarre Riemann surface of them all.


The result is Theorem 5.2 of this article with Alexander Isaev
