  • GENERAL PROPERTIES OF PSEUDO-CONTRACTIBILITY 
    CAPULIN PEREZ, FELIX; OROZCO ZITLI, FERNANDO; JUAREZ VILLA, LEONARDO (TOPOLOGY AND ITS APPLICATION, 2018-07-26)
    General facts about pseudo-homotopies and pseudo-contractibilit topological spaces and continua. As a consequence of these, ditions that obstruct pseudo-contractibility and we present contractible continua and ...
  • Ri-SETS, PSEUDOCONTRACTIBILTY AND WEAK CONTRACTIBILITY ON HYPERSPACES OF CONTINUA 
    CAPULIN PEREZ, FELIX; OROZCO ZITLI, FERNANDO; JUAREZ VILLA, LEONARDO (GLANIK MATEMATICKI, 2018-11-01)
    In this paper we discuss the notions of pseudo-contractibility and weak contractibility on hyperspaces of (Hausdorff) continua. Also we prove that if a continuum X contains an R i -set then it is not pseudocontractible. As ...
  • SEQUENTIAL DECREASING STRONG SIZE PROPERTIES 
    CAPULIN PEREZ, FELIX; OROZCO ZITLI, FERNANDO; LARA MEJÍA, MIGUEL ANGEL (MATHEMATICA SLOVAKA, 2018-12-07)
    Let X be a continuum. The n-fold hyperspace Cn(X), n < 1, is the space of all nonempty closed subsets of X with at most n components. (t). In this paper we show that the following properties are sequential decreasing ...
