Abstract/Media

We describe stable compactification of moduli spaces of bordered Riemann surfaces of any topological type, with boundary and interior marked points. Associahedra (also known as Stasheff polytopes) arise as moduli spaces of disks with no interior marked points; cyclohedra (also known as Bott-Taubes polytopes) arise as moduli spaces of disks with only one interior marked point; halohedra (introduced by Devadoss-Heath-Vipismakul) arise as moduli spaces of annuli with all the marked points on one of the boundary components.
