    Some problems on selections for hyperspace topologies 
    Gutev, Valentin; Nogura, Tsugunori (Universitat Politècnica de València, 2004-04-01)
    [EN] The theory of hyperspaces has attracted the attention of many mathematicians who have found a large variety of its applications during the last decades. The theory has taken also its natural course and has yielded ...

    The topological structure of (homogeneous) spaces and groups with countable cs∗-character 
    Banak, Taras; Zdomskyi, Lubomyr (Universitat Politècnica de València, 2004-04-01)
    [EN] In this paper we introduce and study three new cardinal topological invariants called the cs∗-, cs-, and sb-characters. The class of topological spaces with countable cs∗-character is closed under many topological ...

    Representations of ordered semigroups and the Physical concept of Entropy 
    Candeal, Juan C.; de Miguel, Juan R.; Induráin, Esteban; Mehta, Ghansyam B. (Universitat Politècnica de València, 2004-04-01)
    [EN] The abstract concept of entropy is interpreted throughthe concept of numerical representation of a totally preordered set sothat the concept of composition of systems or additivity of entropy canbe analyzed through ...
