Abstract: The parameter space $ \mathcal{S}_p$ for monic centered cubic polynomial maps with a marked critical point of period $ p$ is a smooth affine algebraic curve whose genus increases rapidly with $ p$. Each $ \mathcal{S}_p$ consists of a compact connectedness locus together with finitely many escape regions, each of which is biholomorphic to a punctured disk and is characterized by an essentially unique Puiseux series. This note will describe the topology of $ \mathcal{S}_p$, and of its smooth compactification, in terms of these escape regions. In particular, it computes the Euler characteristic. It concludes with a discussion of the real sub-locus of $ \mathcal{S}_p$.
