Revisiting Cauty′ s proof of the Schauder conjecture

T Dobrowolski - Abstract and applied analysis, 2003 - Wiley Online Library
The Schauder conjecture that every compact convex subset of a metric linear space has the
fixed‐point property was recently established by Cauty (2001). This paper elaborates on …

A noncompact Schauder fixed point theorem in random normed modules and its applications

T Guo, Y Wang, HK Xu, GX Yuan, G Chen - Mathematische Annalen, 2024 - Springer
Motivated by the randomized version of the classical Bolzano–Weierstrass theorem, in this
paper we first introduce the notion of a random sequentially compact set in a random …

“Lion–Man” and the fixed point property

G López-Acedo, A Nicolae, B Piątek - Geometriae Dedicata, 2019 - Springer

Weak compactness and fixed point property for affine bi-Lipschitz maps

CS Barroso, V Ferreira - Journal of Mathematical Analysis and Applications, 2021 - Elsevier
Let X be a Banach space and let C be a closed convex bounded subset of X. It is proved that
C is weakly compact if, and only if, C has the generic fixed point property (G-FPP) for the …

Linear Uniformalization of the Countable Family of Topological Properties

The well-known theorem on the uniformalization of topological properties [1] has been
strengthened and generalized to the case of a countable family of properties given by …

Approximation by light maps and parametric Lelek maps

T Banakh, V Valov - Topology and its Applications, 2010 - Elsevier
The class of metrizable spaces M with the following approximation property is introduced
and investigated: M∈ AP (n, 0) if for every ε> 0 and a map g: In→ M there exists a 0 …

Parametric bing and Krasinkiewicz maps

V Valov - Topology and its Applications, 2008 - Elsevier
It is shown that if f: X→ Y is a perfect map between metrizable spaces and Y is a C-space,
then the function space C (X, I) with the source limitation topology contains a dense Gδ …

TX Guo, YC Wang, HK Xu, XZ Yuan - arXiv preprint arXiv …, 2021 - academia.edu
Random normed modules (RN modules) are a random generalization of ordinary normed
spaces, which are usually endowed with the two kinds of topologies—the (ε, λ)–topology …
