On (strong) α-favorability of the Wijsman hyperspace

open access: yes, 2010
The Banach–Mazur game as well as the strong Choquet game are investigated on the Wijsman hyperspace from the nonempty player's (i.e. α's) perspective.

On the property of Kelley for Hausdorff continua

open access: yesRevista Integración, 2020
We introduce the concepts Hausdorff maximal limit continuum and Hausdorff strong maximal limit continuum, for Hausdorff continua; these definitions extend the concepts of maximal limit continuum and strong maximal limit continuum, respectiveley ...

Continua whose hyperspace and suspension are homeomorphic

open access: yes, 1978
Let X be a (nonempty metric) continuum. By the hyperspace of X we mean C(X)={A:A is a nonempty subcontinuum of X} with the Hausdorff metric. The suspension S(X) of X is the quotient space (X×[-1, +1])R, where X×[-1, +1] is the cartesian product of X and ...

Concerning the Cone = Hyperspace Property

open access: yes, 1983
In this paper it is shown that a sufficient condition for a continuum X to have the cone = hyperspace property is that there exists a selection for C(X)\{X} which, for some Whitney map for C(X), maps each nondegenerate Whitney level homeomorphically onto

Application of a Selection Theorem to Hyperspace Contractibility

open access: yes, 1985
For X a metric continuum, 2X denotes the hyper space of all nonempty subcompacta, with the topology induced by the Hausdorff metric H, and C(X) ⊂ 2X the hyperspace of subcontinua. These hyperspaces are continua, in fact are arcwise-connected, since there

On First Countability of a New Hyperspace Topology

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2014
In this paper the notion of first countability of the hyperspace (θ (X), τ ) has been studied and being compared with that of X.

On the n-fold hyperspace suspension of continua, II

open access: yes, 2006
We continue our study of n-fold hyperspace suspensions. We show that n-fold hyperspace suspensions of contractible continua are contractible. We prove that n-fold hyperspace suspensions are zero-dimensional aposyndetic.
