Abstract

top
We prove that the cardinality of power homogeneous Hausdorff spaces X is bounded by d ( X ) π χ ( X ) . This inequality improves many known results and it also solves a question by J. van Mill. We further introduce Δ-power homogeneity, which leads to a new proof of van Douwen’s theorem.
