CHAOS ON HYPERSPACE

International Journal of Bifurcation and Chaos, 2013
In this paper, the chaotic behavior of a set-valued mapping F : X → 2X, where X is a compact space, is investigated. The existence of the generalized shadowing property in the hyperspace 2X is proved. Based on the generalized shadowing property of the set-valued mappings F and the assumption of the existence of an unstable chain recurrent point of the

Existence of selections and disconnectedness properties for the hyperspace of an ultrametric space

Topology and Its Applications, 1998
We characterize the separable complete ultrametric spaces whose Wijsman hyperspace admits a continuous selection; such an investigation is closely connected to a similar result of V. Gutev about the Ball hyperspace.

Scouts in hyperspace

Computers & Graphics, 1989
Abstract A one-person, checkers-like pegboard game in n -space is described. The goal of the game is to advance a peg as far as possible from an initial configuration of pegs. Using an argument based on the golden mean, we demonstrate bounds for how far a peg can travel as well as how many pegs are needed to achieve a particular goal.

Intelligent mapping of hyperspace

Proceedings IEEE/WIC International Conference on Web Intelligence (WI 2003), 2004
We address some particular issues related to the difficult task of automatically structuring information available in illstructured environments, through a distributed hypermedia system like the Web. We present an original approach to this problem, which coordinates different aspects of automatic computation of relations between nodes in hyperspace ...

Covering Hyperspace with Hypercurves

Mathematical Logic Quarterly, 1991
In 1962, Davies showed that for each sequence \(\langle L_ i\rangle_{i\in\omega}\) of pairwise distinct lines in the plane each of which goes through the origin, there is a covering \(\langle E_ i\rangle_{i\in\omega}\) of the plane s.t. \(\forall i\in\omega\), every line parallel to \(L_ i\) intersects \(E_ i\) in exactly one point.

A Note on Ultracomplete Hyperspaces

Bulletin of the Iranian Mathematical Society, 2022
The hyperspace of all non-empty compact subsets of a given space \(X\), equipped with the Vietoris topology, is denoted by \(K(X)\). A space \(X\) is \(\omega\)-hyperbounded if the closure of any \(\sigma\)-compact subspace of \(X\) is compact, a notion introduced in [\textit{J. Angoa} et al., Mat. Vesn. 65, No. 3, 306--318 (2013; Zbl 1313.54026)].

The hyperspace of a compact space, I

Topology and Its Applications, 1996
We investigate the properties monolithic and d-separable for the hyperspace H(X) of all nonempty closed subsets of a compact Hausdorff space X. A. Arhangelskii has asked whether H(X) monolithic is equivalent to X metrizable. We answer this with: Let X be
