    On spaces with the property (wa) 
    Song, Yan-Kui (Universitat Politècnica de València, 2006-04-01)
    [EN] A space X has the property (wa) (or is a space with the property (wa)) if for every open cover U of X and every dense subspace D of X, there exists a discrete subspace F C D such that St(F, U) = X. In this paper, we ...

    On nearly Hausdorff compactifications 
    Shah, Sejal; Das, T.K. (Universitat Politècnica de València, 2006-04-01)
    [EN] We introduce and study here the notion of nearly Hausdorffness, a separation axiom, stronger than T1 but weaker than T2. For a space X, from a subfamily of the family of nearly Hausdorff spaces, we construct a compact ...

    Making group topologies with, and without, convergent sequences 
    Comfort, W.W.; Raczkowski, S.U.; Trigos-Arrieta, F.J. (Universitat Politècnica de València, 2006-04-01)
    [EN] (1) Every infinite, Abelian compact (Hausdorff) group K admits 2|K|- many dense, non-Haar-measurable subgroups of cardinality |K|. When K is nonmetrizable, these may be chosen to be pseudocompact. (2) Every infinite ...

    Tightness of function spaces 
    Lin, Shou (Universitat Politècnica de València, 2006-04-01)
    [EN] The purpose of this paper is to give higher cardinality versions of countable fan tightness of function spaces obtained by A. Arhangel’skiı. Let vet(X), ωH(X) and H(X) denote respectively the fan tightness, ω-Hurewicz ...

    On RG-spaces and the regularity degree 
    Raphael, R.; Woods, R.G. (Universitat Politècnica de València, 2006-04-01)
    [EN] We continue the study of a lattice-ordered ring G(X), associated with the ring C(X). Following, X is called RG when G(X) = C(Xδ). An RG-space must have a dense set of very weak P-points. It must have a dense set of ...
