Continua with unique symmetric product
, 2009 summary:Let $X$ be a metric continuum. Let $F_{n}(X)$ denote the hyperspace of nonempty subsets of $X$ with at most $n$ elements. We say that the continuum $X$ has unique hyperspace $F_{n}(X)$ provided that the following implication holds: if $Y$ is a ...

The Scientific romances of Charles Howard Hinton : the fourth dimension as hyperspace, hyperrealism and protomodernism [PDF]
, 2007 This thesis examines the epistemological, socio-cultural and aesthetic impact of the hyperspace philosophy of Charles Howard Hinton, as expressed within his two-volume collection of Scientific Romances (1884-1896).

Concerning n-mutual aposyndesis in hyperspaces
, 2012 Given a metric continuum X, let 2X denote the hyperspace of nonempty closed subsets of X. We prove that 2X is n-mutually aposyndetic for each n≥ 1. That is, given n distinct elements of 2X, there are n disjoint subcontinua of 2X, each containing one of ...

THE HYPERSPACE OF CLOSED CONNECTED SUBSETS OF A EUCLIDEAN SPACE
, 2014 . Let R n denote n-dimensional Euclidean space and C(R n) denote the hyperspace of closed connected subsets of R n, with the Vietoris topology. The following results are obtained: (1) C(R 1) is homeomorphic to R 1 × [0, 1] and hence is locally compact ...

Efficacy of a map on search, orientation and access behaviour in a hypermedia system
, 2000 Many researchers have proposed hypertext and hypermedia as superior learning environments over traditional linear-based approaches. At the same time, reports of disorientation amongst students working in these environments has become a topic of major ...

Selections and hyperspaces of finite sets
, 2010 It is demonstrated that the hyperspace of at most (n+1)-point sets has a Vietoris continuous selection if both the hyperspace of at most n-point sets and that of exactly (n+1)-point sets have Vietoris continuous selections.

Implicit Measures of Lostness and Success in Web Navigation [PDF]
, 2007 In two studies, we investigated the ability of a variety of structural and temporal measures computed from a web navigation path to predict lostness and task success. The user’s task was to find requested target information on specified websites. The web
