Tilings in topological spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
A tiling of a topological space X is a covering of X by sets (called tiles) which are the closures of their pairwise-disjoint interiors. Tilings of ℝ2 have received considerable attention (see [2] for a wealth of interesting examples and results as well ...

Examples of differentiable mappings into non-locally convex spaces

open access: yes, 2003
Examples of differentiable mappings into real or complex topological vector spaces with specific properties are given, which illustrate the differences between differential calculus in the locally convex and the non-locally convex case.

Motion planning algorithms, topological properties and affine approximation

open access: yesBulletin of Computational Applied Mathematics, 2015
The topological study of the so-called "motion planning algorithms" emerged in the 2003-2004 with the works of M. Farber. We focus here on the topological study of the set of these algorithms, when the configuration space is a normed vector space.

Differential geometric invariants for time-reversal symmetric Bloch-bundles II: The low dimensional "Quaternionic" case

open access: yes, 2018
This paper is devoted to the construction of differential geometric invariants for the classification of "Quaternionic" vector bundles. Provided that the base space is a smooth manifold of dimension two or three endowed with an involution that leaves ...

On almost \(s-\)topological vector spaces

open access: yesJournal of Advanced Studies in Topology, 2018
In this paper, we introduce the notion of almost \(s-\)topological vector spaces and present some examples and counterexamples of almost \(s-\)topological vector spaces. Some general properties of almost \(s-\)topological vector spaces are investigated.

Topological properties and matrix transformations of certain ordered generalized sequence spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
In this note, we carry out investigations related to the mixed impact of ordering and topological structure of a locally convex solid Riesz space (X,τ) and a scalar valued sequence space λ, on the vector valued sequence space λ(X) which is formed and ...

Extremal properties of the set of vector-valued Banach limits

open access: yesOpen Mathematics, 2015
In this manuscript we find another class of real Banach spaces which admit vector-valued Banach limits different from the classes found in [6, 7]. We also characterize the separating subsets of ℓ∞(X).

A Vector Supersymmetry Killing the Infrared Singularity of Gauge Theories in Noncommutative Space

open access: yes, 2006
We show that the "topological BF-type" term introduced by Slavnov in order to cure the infrared divergences of gauge theories in noncommutative space can be characterized as the consequence of a new symmetry.

Extending Topological Abelian Groups by the Unit Circle

open access: yesAbstract and Applied Analysis, 2013
A twisted sum in the category of topological Abelian groups is a short exact sequence 0→Y→X→Z→0 where all maps are assumed to be continuous and open onto their images. The twisted sum splits if it is equivalent to 0→Y→Y×Z→Z→0.
