Finite compactifications of $\omega^* \setminus \{x\}$

General Topology 2013-11-22 v1

Abstract

We prove that under [CH], finite compactifications of ω{x}\omega^* \setminus \{x\} are homeomorphic to ω\omega^*. Moreover, in each case, the remainder consists almost exclusively of PP-points, apart from possibly one point. Similar results are obtained for other, related classes of spaces, amongst them SκS_\kappa, the κ\kappa-Parovi\v{c}enko space of weight κ\kappa. Also, some parallels are drawn to the Cantor set and the Double Arrow space.
