Retracting the moduli space of curves
In this talk I will present Harer's mapping-class-group-equivariant spine of the Teichmueller space of a punctured surface. From this it follows that the rational Betti numbers of the moduli space of the surface start to vanish in degrees far lower than the topological dimension. Speaker(s): Bradley Zykoski (UM)
