    On density and π-weight of Lp(βN,R, μ) 
    Iurato, Giuseppe (Universitat Politècnica de València, 2012-04-01)
    [EN] The new topological concept of selective separability is able to give some estimates for density and π-weight of the Lebesgue space Lp(βN,R, μ) with 1 ≤ p < +∞. In particular, we deduce a purely topological proof of ...

    Hausdorff closed extensions of pre-uniform spaces 
    García-Máynez, Adalberto; Mancio-Toledo, Rubén (Universitat Politècnica de València, 2012-04-01)
    [EN] The family of densely finite open covers of a Hausdorff space X determines a completable pre-uniformity on X and the canonical completion X is Hausdorff closed. We compare X with the Katetov extension kX of X and give ...

    Extending maps between pre-uniform spaces 
    García-Máynez, Adalberto; Mancio-Toledo, Rubén (Universitat Politècnica de València, 2012-04-01)
    [EN] We give sufficient conditions on a uniformly continuous map f: (X,U) → (Y, V ) between completable T1-pre-uniform spaces (X,U), (Y, V ) to have a continuous or a uniformly continuous extension f:X → Y between the ...

    Some results and examples concerning Whyburn spaces 
    Alas, Ofelia T.; Madriz-Mendoza, Maira; Wilson, Richard G. (Universitat Politècnica de València, 2012-04-01)
    [EN] We prove some cardinal inequalities valid in the classes of Whyburn and hereditarily weakly Whyburn spaces and we construct examples of non-Whyburn and non-weakly Whyburn spaces to illustrate that some previously known ...

    On cofree S-spaces and cofree S-flows 
    Khosravi, Behnam (Universitat Politècnica de València, 2012-04-01)
    [EN] Let S-Tych be the category of Tychonoff S-spaces for a topological monoid S. We study the cofree S-spaces and cofree S-flows over topological spaces and we prove that for any topological space X and a topological ...
