    Maximal balleans 
    Protasova, Olga I. (Universitat Politècnica de València, 2006-10-01)
    [EN] A ballean is a set X endowed with some family of subsets of X which are called the balls. We postulate the properties of the family of balls in such a way that the balleans with the appropriate morphisms can be ...

    Connected metrizable subtopologies and partitions into copies of the Cantor set 
    Druzhinina, Irina (Universitat Politècnica de València, 2006-10-01)
    [EN] We prove under Martin’s Axiom that every separable metrizable space represented as the union of less than 2 ω zero-dimensional compact subsets is zero-dimensional. On the other hand, we show in ZFC that every separable ...

    Every infinite group can be generated by P-small subset 
    Dikranjan, Dikran; Protasov, Igor (Universitat Politècnica de València, 2006-10-01)
    [EN] For every infinite group G and every set of generators S of G, we construct a system of generators in S which is small in the sense of Prodanov.

    The ideal generated by σ-nowhere dense sets 
    Cao, Jiling; Greenwood, Sina (Universitat Politècnica de València, 2006-10-01)
    [EN] In this paper, we consider the ideal Iσ generated by all σ-nowhere dense sets in a topological space. Properties of this ideal and its relations with the Volterra property are explored. We show that Iσ is compatible ...

    Uniformly discrete hit-and-miss hypertopology. A missing link in hypertopologies 
    Di Maio, Giuseppe; Meccariello, Enrico; Naimpally, Somashekhar (Universitat Politècnica de València, 2006-10-01)
    [EN] Recently it was shown that the lower Hausdorff metric (uniform) topology is generated by families of uniformly discrete sets as hit sets. This result leads to a new hypertopology which is the join of the above topology ...
