Abstract: A discussion of two moduli spaces and their awkward topologies: first the space of divisors on the Riemann sphere modulo the action of Moebius automophisms; and second the (compactified) space of curves in the complex projective plane modulo projective automorphisms.This is joint work with Araceli Bonifant.
