    Topological groups: local versus global 
    Arhangelskii, A.V.; Uspenskij, Vladimir V. (Universitat Politècnica de València, 2006-04-01)
    [EN] It is well known that locally compact groups are paracompact. We observe that this theorem can be generalized as follows: every locally paracompact group is paracompact. We prove a more general version of this statement ...

    On i-topological spaces: generalization of the concept of a topological space via ideals 
    Zvina, Irina (Universitat Politècnica de València, 2006-04-01)
    [EN] The aim of this paper is to generalize the structure of a topological space, preserving its certain topological properties. The main idea is to consider the union and intersection of sets modulo “small” sets which are ...

    Criteria of strong nearest-cross points and strong best approximation pairs 
    Pan, Wenxi; Xu, Jingshi (Universitat Politècnica de València, 2006-04-01)
    [EN] The concept of strong nearest-cross point (strong n.c. point) is introduced, which is the generalization of strong uniqueness of best approximation from a single point. The relation connecting to localization is ...

    Weakly metrizable pseudocompact groups 
    Dikranjan, Dikran; Giordano Bruno, Anna; Milan, Chiara (Universitat Politècnica de València, 2006-04-01)
    [EN] We study various weaker versions of metrizability for pseudocompact abelian groups G: singularity (G possesses a compact metrizable subgroup of the form mG, m > 0), almost connectedness (G is metrizable modulo the ...
