    A characterization of pseudocompactness by Prabduh Ram Misra, Vinodkumar

    Published 1981-01-01
    “…It is proved here that a completely regular Hausdorff space X is pseudocompact if and only if for any continuous function f from X to a pseudocompact space (or a compact space) Y, f*ϕ is z-ultrafilter whenever ϕ is a z-ultrafilter on X.…”

    Schwarz-Pick Estimates for Holomorphic Mappings with Values in Homogeneous Ball by Jianfei Wang

    Published 2012-01-01
    “…Let BX be the unit ball in a complex Banach space X. Assume BX is homogeneous. The generalization of the Schwarz-Pick estimates of partial derivatives of arbitrary order is established for holomorphic mappings from the unit ball Bn to BX associated with the Carathéodory metric, which extend the corresponding Chen and Liu, Dai et al. results.…”

    A note on nonfragmentability of Banach spaces by S. Alireza Kamel Mirmostafaee

    Published 2001-01-01
    “…We use Kenderov-Moors characterization of fragmentability to show that if a compact Hausdorff space X with the tree-completeness property contains a disjoint sequences of clopen sets, then (C(X), weak) is not fragmented by any metric which is stronger than weak topology. …”
