Abstract

We consider the open moduli space M 2,1 of complex curves of genus 2 with one marked point. Using the language of chord diagrams, we describe the cell structure of M 2,1 and cell adjacency. This allows us to construct matrices of boundary operators and compute Betty numbers of M 2,1 over ℚ.
