    A note on weakly pseudocompact locales 
    Dube, Themba (Universitat Politècnica de València, 2017-04-03)
    [EN] We revisit weak pseudocompactness in pointfree topology, and show that a locale is weakly pseudocompact if and only if it is Gδ-dense in some compactification. This localic approach (in contrast with the earlier ...

    On the generalized asymptotically nonspreading mappings in convex metric spaces 
    Phuengrattana, Withun (Universitat Politècnica de València, 2017-04-03)
    [EN] In this article, we propose a new class of nonlinear mappings, namely, generalized asymptotically nonspreading mapping, and prove the existence of fixed points for such mapping in convex metric spaces. Furthermore, ...

    On cardinalities and compact closures 
    Krebs, Mike (Universitat Politècnica de València, 2017-04-03)
    [EN] We show that there exists a Hausdorff topology on the set R of real numbers such that a subset A of R has compact closure if and only if A is countable. More generally, given any set X and any infinite set S, we prove ...

    Fixed point theorems for simulation functions in $\mbox{b}$-metric spaces via the $wt$-distance 
    Mongkolkeha, Chirasak; Cho, Yeol Je; Kumam, Poom (Universitat Politècnica de València, 2017-04-03)
    [EN] The purpose of this article is to prove some fixed point theorems for simulation functions in complete b-metric spaces with partially ordered by using wt-distance which introduced by Hussain et al. Also, we ...

    A new cardinal function on topological spaces 
    Sari, Dewi Kartika; Zhao, Dongsheng (Universitat Politècnica de València, 2017-04-03)
    [EN] Using neighbourhood assignments, we introduce and study a new cardinal function, namely GCI(X), for every topological space X. We shall mainly investigate the spaces X with finite GCI(X). Some properties of this ...
