    Alternate product adjacencies in digital topology 
    Boxer, Laurence (Universitat Politècnica de València, 2018-04-02)
    [EN] We study properties of Cartesian products of digital images, using a variety of adjacencies that have appeared in the literature.

    Fixed poin sets in digital topology, 1 
    Boxer, Laurence; Staecker, P. Christopher (Universitat Politècnica de València, 2020-04-03)
    [EN] In this paper, we examine some properties of the fixed point set of a digitally continuous function. The digital setting requires new methods that are not analogous to those of classical topological fixed point theory, ...

    Generalized Normal Product Adjacency in Digital Topology 
    Boxer, Laurence (Universitat Politècnica de València, 2017-10-02)
    [EN] We study properties of Cartesian products of digital images for which adjacencies based on the normal product adjacency are used. We show that the use of such adjacencies lets us obtain many "product properties" for ...

    Range-preserving AE(0)-spaces 
    Comfort, W.W.; Hager, A.W. (Universitat Politècnica de València, 2013-04-01)
    [EN] All spaces here are Tychonoff spaces. The class AE(0) consists of those spaces which are absolute extensors for compact zero-dimensional spaces. We define and study here the subclass AE(0)rp, consisting of those spaces ...
