  • AGUJEROS EN EL HIPERESPACIO DE SUBCONTINUOS DE CIERTOS CONTINUOS 
    Carranza Cruz, Rosa Isela; Maya Escudero, David; Orozco Zitli, Fernando; Anaya Ortega, José Guadalupe (Topology and its Applications, 2017-10-17)
    A continuum is a non-degenerate compact connected metric space. Let C(X) be the hyperspace of all subcontinua of X. An element A2C(X) makes a hole in C(X) ifC(X){A} is not unicoherent. In this paper, we characterize the ...
  • 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 ...
  • Hollowing the hyperspace of subcontinua of dendrites 
    ANAYA ORTEGA, JOSE GUADALUPE; Maya Escudero, David; Carranza Cruz, Rosa Isela; Orozco Zitli, Fernando (Elsevier, 2023-11-01)
    Let C(X) be the hyperspace of all subcontinua of a metric continuum X. An element A ∈ C(X) hollows to C(X) provided μ−1(μ(A)) − {A} is connected and non- unicoherent for each Whitney map μ for C(X). In this paper the ...
  • Lipschitz retractions on symmetric products of trees 
    Castañeda Alvarado, Enrique; Orozco Zitli, Fernando; Reyes Quiroz, Mónica Andrea (Indian national science academy, 2021-06-14)
    Given a continuum X and a positive integer n, Fn(X) denotes the hyperspace of non-empty subsets of X with at most n elements, endowed with the Hausdorff metric. In this article, given X a simple m-od, we prove that Fn-1(X) ...
  • 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 ...
  • The hyperspace F_n^K(X) 
    Castañeda Alvarado, Enrique; Mondragón, Roberto Carlos; Ordoñez Ramírez, Norberto; Orozco Zitli, Fernando (Springer, 2020-06-12)
    Given a metric continuum X and a positive integer n, Fn(X) denotes the hyperspace of all nonempty subsets of X with at most n points endowed with the Hausdorff metric. For any K ∈ Fn(X), we define Fn(K, X) as the collection ...
