Mots et discours de science dans la science-fiction
Socio, 2019 Science fiction has close ties with science, as we know, but this article focuses more specifically on the words of science, the scientific vocabulary, which we often find in science fiction texts and, in particular, on the enlightening way in which ...

On some cardinal invariants of space of finite subsets
Lietuvos Matematikos Rinkinys, 2005 In article is investigated relationships between some cardinal invariants of topological space and it’s space of finite subsets with Vietoris topology. In generalwe note coincidence of them.

Dynamic to Quotients of Hyperspaces
Zurnal matematiceskoj fiziki, analiza, geometrii, 2022 Summary: Let \((X,d)\) be a compact metric space and let \(n\) be a positive integer. Let \(\mathcal{C}_n(X)\) be the space of all nonempty closed subsets of \(X\) with at most \(n\) components and let \(\mathcal{F}_1(X)\) be the space of singletons of \(X\). Given a map \(f : X \rightarrow X\), we consider the induced map \(\mathcal{C}_n(f) : \mathcal{

The hyperspace of totally disconnected sets
, 2020 In this paper we study the hyperspace of all nonempty closed totally disconnected subsets of a space, equipped with the Vietoris topology. We show results of compactness, connectedness and local connectedness for this hyperspace.

Higher spins in hyperspace [PDF]
, 2014 We consider the Sp(2n) invariant formulation of higher spin fields on flat and curved backgrounds of constant curvature. In this formulation an infinite number of higher spin fields are packed into single scalar and spinor master fields (hyperfields ...

The lifting property for classes of mappings
International Journal of Mathematics and Mathematical Sciences, 2000 The lifting property of continua for classes of mappings is defined. It is shown that the property is preserved under the inverse limit operation. The results, when applied to the class of confluent mappings, exhibit conditions under which the induced ...

Lifting Dynamical Properties to Hyperspaces
Applied General Topology, 2014 For a dynamical system (X,f), the passage of various dynamical properties such as transitivity, total transitivity, weakly mixing, mixing, topological exactness, topological conjugacy, to the hyperspace C(X) of X consisting of nonempty closed connected ...

Selection principles and bitopological hyperspaces
Applied General Topology, 2023 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 2X the family of all closed subsets of X.

Quality and Reliability Engineering International, EarlyView.ABSTRACT We propose a practical procedure to quantify the time varying influence of parameters on hazard functions for power series compounded lifetime models. The procedure combines likelihood based fitting with a two stage sensitivity analysis and applies to a range of baselines and compounding laws.
