These ideas have considerable scope for further development, and a list of problems and lines of research is included. Anderson: Hilbert space is homeomorphic to the countable infinite product of lines. A Brief Survey of Hyperspaces and a Construction of a Whitney Map Sean O’Neill Master of Science, Aug(B.S., Ohio University, 2006) 31 Typed Pages Directed by Michel Smith This paper is a brief survey of hyperspaces of topological spaces. It is also shown that every (not necessarily bounded geometry) metric space with straight finite decomposition complexity has metric sparsification property. This leads to new, elegant concepts (defined purely topologically) of self-similarity and fractality: in particular, the author shows that many invariant sets are "visually fractal", i.e. : Hyperspaces of Sets: A Text with Research Questions (Monographs and Textbooks in Pure and Applied Mathematics): 9780824767686: Sam B. As a corollary, the hyperspace of finite subsets of the real line is not coarsely embeddable into any uniformly convex Banach space.

Dugundji, Topology Allyn and Bacon Series in Advanced Mathematics 1976. The last and most original part of the book introduces the notion of a "view" as part of a framework for studying the structure of sets within a given space. R.Duda, On the hyperspace of subcontinua of a nite graph I, Fund. In this context, we consider the Zadeh’s extension f of f to F(X), the family of all. The text contains examples and exercises. Given a metric space (X,d), we deal with a classical problem in the theory of hyperspaces: how some important dynamical properties (namely, weakly mixing, transitivity and point-transitivity) between a discrete dynamical system f:(X,d)&rarr (X,d) and its natural extension to the hyperspace are related. Topics include the topology for hyperspaces, examples of geometric models for hyperspaces, 2x and C(X) for Peano continua X, arcs in hyperspaces, the shape and contractability of hyperspaces, hyperspaces and the fixed point property, and Whitney maps. Hutchinson's invariant sets (sets composed of smaller images of themselves) is developed, with a study of when such a set is tiled by its images and a classification of many invariant sets as either regular or residual. Presents hyperspace fundamentals, offering a basic overview and a foundation for further study. A major feature is that nonstandard analysis is used to obtain new proofs of some known results much more slickly than before. The first part of the book develops certain hyperspace theory concerning the Hausdorff metric and the Vietoris topology, as a foundation for what follows on self-similarity and fractality. Addressed to all readers with an interest in fractals, hyperspaces, fixed-point theory, tilings and nonstandard analysis, this book presents its subject in an original and accessible way complete with many figures.
