Selection principles and bitopological hyperspaces [PDF]
, 2023 [EN] In this paper we continue to research relationships between closure-type properties of hyperspaces over a space X and covering properties of X. For a Hausdorff space X we denote by 2 X the family of all closed subsets of X.

ON SOME CONVERGENCE PROPERTIES OF HYPERSPACES WITH HIT-AND-MISS TOPOLOGY [PDF]
, 2022 In this paper the relationships between closure type properties of hyperspaces over a space $X$ with that of covering properties of $X$ are being investigated. Our main focus here is to study $\alpha_{_{i}}$-properties of $X$ and that of hyperspaces with

Vietoris hyperspaces of scattered Priestley spaces [PDF]
, 2021 We study Vietoris hyperspaces of closed and closed final sets of Priestley spaces. We are particularly interested in Skula topologies. A topological space is \emph{Skula} if its topology is generated by differences of open sets of another topology.

Topology change and context dependence [PDF]
, 1999 The nonclassical features of quantum mechanics are reproduced using models constructed with a classical theory-general relativity. The inability to define complete initial data consistently and independently of future measurements, nonlocality, and the ...

Disconnectedness properties of hyperspaces [PDF]
, 2011 summary:Let $X$ be a Hausdorff space and let $\mathcal H$ be one of the hyperspaces $CL(X)$, $\mathcal K(X)$, $\mathcal F(X)$ or $\mathcal F_n(X)$ ($n$ a positive integer) with the Vietoris topology. We study the following disconnectedness properties for

Convexity in quasi-metric spaces [PDF]
, 2012 Includes abstract.Includes bibliographical references.The principal aim of this thesis is to investigate the existence of an injective hull in the categories of T-quasi-metric spaces and of T-ultra-quasi-metric spaces with nonexpansive ...

Cellular structures in Topology [PDF]
, 1990 This book describes the construction and the properties of CW-complexes. These spaces are important because firstly they are the correct framework for homotopy theory, and secondly most spaces that arise in pure mathematics are of this type.

Hyperspaces and Function Graphs in Digital Topology
, 2023 We adapt the study of hyperspaces and function spaces from classical topology to digital topology. We define digital hyperspaces and digital function graphs, and study some of their relationships and graphical ...

The hyperspaces Cn(X) for finite ray-graphs [PDF]
, 2013 In this paper we consider the hyperspace Cn(X) of non-empty and closed subsets of a base space X with up to n connected components. The class of base spaces we consider we call finite ray-graphs, and are a noncompact variation on finite graphs.
