Nonsymmetric distances and their associated topologies: about the origins of basic ideas in the area of asymmetric topology

HPA Künzi - Handbook of the history of general topology, 2001 - Springer
We begin with some remarks explaining the structure of this article. After some introductory
statements in the following paragraphs, we summarize the historic development of what is …

The Tukey order on compact subsets of separable metric spaces

P Gartside, A Mamatelashvili - The Journal of Symbolic Logic, 2016 - cambridge.org
One partially ordered set, Q, is a Tukey quotient of another, P, if there is a map (a Tukey
quotient)'s under Tukey quotients is investigated. Relative Tukey quotients are introduced …

On -Pseudocompactess and Uniform Homeomorphisms of Function Spaces

M Krupski - Results in Mathematics, 2023 - Springer
A Tychonoff space X is called κ-pseudocompact if for every continuous mapping f of X into R
κ the image f (X) is compact. This notion generalizes pseudocompactness and gives a …

On uniformly continuous surjections between -spaces over metrizable spaces

A Eysen, A Leiderman, V Valov - arXiv preprint arXiv:2408.01870, 2024 - arxiv.org
Let $ X $ and $ Y $ be metrizable spaces and suppose that there exists a uniformly
continuous surjection $ T: C_ {p}(X)\to C_ {p}(Y) $(resp., $ T: C_ {p}^*(X)\to C_ {p}^*(Y) $) …

Tukey order on sets of compact subsets of topological spaces

A Mamatelashvili - 2014 - search.proquest.com
A partially ordered set (poset), Q, is a Tukey quotient of a poset, P, written P≥ TQ, if there
exists a map, a Tukey quotient, &phis;: P→ Q such that for any cofinal subset C of P the …

On uniformly continuous surjections between function spaces

AE Eysen, V Valov - arXiv preprint arXiv:2404.00542, 2024 - arxiv.org
We consider uniformly continuous surjections between $ C_p (X) $ and $ C_p (Y) $(resp, $
C_p^*(X) $ and $ C_p^*(Y $)) and show that if $ X $ has some dimensional-like properties …

Internal descriptions of absolute Borel classes

P Holický, J Pelant - Topology and its Applications, 2004 - Elsevier
We present internal descriptions of spaces of absolute Borel classes with respect to
Tychonoff spaces. Complete sequences of covers is the basic tool for this description. We …

A relation between spaces implied by their t-equivalence

O Okunev - Topology and its Applications, 2011 - Elsevier
We prove that if X and Y are t-equivalent spaces (that is, if C p (X) and C p (Y) are
homeomorphic), then there are spaces Z n, locally closed subspaces B n of Z n, and locally …
