Dynamical systems of finite-dimensional metric spaces and zero-dimensional covers

Y Ikegami, H Kato, A Ueda - Topology and its Applications, 2013 - Elsevier
In this paper, we assume that dimensions mean the large inductive dimension Ind and the
covering dimension dim. It is well known that IndX= dimX for each metric space XJ Kulesza …

On colorings of maps

MA van Hartskamp, J Vermeer - Topology and its Applications, 1996 - Elsevier
A fixed-point free map f: X→ X is said to be colorable with k colors if there exists a closed
cover C of X consisting of k elements such that C∩ f (C)=∅ for every C in C. It is shown that …

Eventual colorings of homeomorphisms

Y Ikegami, H Kato, A Ueda - Journal of the Mathematical Society of …, 2013 - jstage.jst.go.jp
In this paper, we study some dynamical properties of fixedpoint free homeomorphisms of
separable metric spaces. For each natural number p, we define eventual colorings within p …

[PDF][PDF] On eventual coloring numbers

Y Ikegami, H Kato, A Ueda - Topology Proceedings, 2016 - topology.nipissingu.ca
In [6], for each natural number p we defined eventual colorings within p of homeomorphisms
which are generalizations of colorings of fixed-point free homeomorphisms, and we …

Schauder's fixed point and amenability of a group

SA Bogatyi, VV Fedorchuk - 2007 - projecteuclid.org
A criterion for existence of a fixed point for an affine action of a given group on a compact
convex space is presented. From this we derive that a discrete countable group is amenable …

An addition theorem for the color number

J Aarts, R Fokkink - Proceedings of the American Mathematical Society, 2001 - ams.org
There is a close relation between the color number of a continuous map $ f\colon X\to X $
without fixed points and the topological dimension. If $ f $ is an involution, the color number …

Coincidence theorems for involutions

JM Aarts, RJ Fokkink, H Vermeer - Topology and its Applications, 1998 - Elsevier
Ščepin (1974) and Izydorek and Jaworowski (1995, 1996) showed that for each k and n
such that 2k> n there exists a contractible k-dimensional simplicial complex Y and a …

Coloring maps of period three

JM Aarts, RJ Fokkink, J Vermeer - Pacific journal of mathematics, 2002 - msp.org
We investigate the color number and genus for fixed-point free maps of order three. A result
that has the flavor of the Ljusternik-Schnirelmann theorem for involutions is established. The …

Intersection properties for coverings of G-spaces

JM Aarts, GA Brouwer, RJ Fokkink, J Vermeer - Topology and its …, 2002 - Elsevier
The Ljusternik–Schnirelmann–Borsuk theorem for antipodal maps on the sphere can be
stated as an intersection property of coverings of the sphere. We generalized this theorem to …
