    F-points in countably compact spaces 
    Bella, Angelo; Malykhin, V.I. (Universitat Politècnica de València, 2001-04-01)
    [EN] Answering a question of A.V. Arhangel'skii, we show that any extremally disconnected subspace of a compact space with countable tightness is discrete.

    Few remarks on maximal pseudocompactness 
    Bella, Angelo (Universitat Politècnica de València, 2018-04-02)
    [EN] A pseudocompact space is maximal pseudocompact if every strictly finer topology is no longer pseudocompact. The main result here is a counterexample which answers a question rised by Alas, Sanchis and Wilson.

    Iterated starcompact topological spaces 
    Kim, Junhui (Universitat Politècnica de València, 2004-04-01)
    [EN] Let P be a topological property. A space X is said to be k-P-starcompact if for every open cover U of X, there is a subspace A C X with P such that stk(A,U) = X. In this paper, we consider k-P- starcompactness for ...

    Spaces whose Pseudocompact Subspaces are Closed Subsets 
    Dow, Alan; Porter, Jack R.; Stephenson, R.M.; Grant Woods, R. (Universitat Politècnica de València, 2004-10-01)
    [EN] Every first countable pseudocompact Tychonoff space X has the property that every pseudocompact subspace of X is a closed subset of X (denoted herein by “FCC”). We study the property FCC and several closely related ...

    The character of free topological groups I 
    Nickolas, Peter; Tkachenko, Mikhail (Universitat Politècnica de València, 2005-04-01)
    [EN] A systematic analysis is made of the character of the free and free abelian topological groups on uniform spaces and on topological spaces. In the case of the free abelian topological group on a uniform space, expressions ...

    The character of free topological groups II 
    Nickolas, Peter; Tkachenko, Mikhail (Universitat Politècnica de València, 2005-04-01)
    [EN] A systematic analysis is made of the character of the free and free abelian topological groups on metrizable spaces and compact spaces, and on certain other closely related spaces. In the first case, it is shown that ...
