Locally compact convergence groups and n-transitive actions [PDF]

open access: yes, 2012
All sigma-compact, locally compact groups acting sharply n-transitively and continuously on compact spaces M have been classified, except for n=2,3 when M is infinite and disconnected. We show that no such actions exist for n=2 and that these actions for

Finite Unions of D-Spaces and Applications of Nearly Good Relation

open access: yesDiscrete Dynamics in Nature and Society, 2013
Some results are obtained on finite unions of D-spaces. It is proved that if a space is the union of finitely many locally compact D-subspaces, then it is a D-space. It follows that a space is a D-space if it is the union of finitely many locally compact

Non-positive curvature and the Ptolemy inequality [PDF]

open access: yes, 2007
We provide examples of non-locally compact geodesic Ptolemy metric spaces which are not uniquely geodesic. On the other hand, we show that locally compact, geodesic Ptolemy metric spaces are uniquely geodesic.

Lifting Theorems for Continuous Order-Preserving Functions and Continuous Multi-Utility

open access: yesAxioms, 2023
We present some lifting theorems for continuous order-preserving functions on locally and σ-compact Hausdorff preordered topological spaces. In particular, we show that a preorder on a locally and σ-compact Hausdorff topological space has a continuous ...

A local characterization of Kazhdan projections and applications [PDF]

open access: yes, 2018
We give a local characterization of the existence of Kazhdan projections for arbitary families of Banach space representations of a compactly generated locally compact group $G$.

Dissipative conformal measures on locally compact spaces [PDF]

open access: yes, 2014
The paper introduces a general method to construct conformal measures for a local homeomorphism on a locally compact non-compact Hausdorff space, subject to mild irreducibility-like conditions.

On T-locally compact spaces

open access: yes, 2022
The aim of this paper is to introduce and give preliminary investigation of T-locally compact spaces. Locally compact and T-locally compact are independent of each other. Every Hausdorff, locally compact space is T-locally compact. T-locally compact is a topological property. T-locally compact is not preserved by the product topology.

Pairwise locally compact and compactification in

open access: yesJournal of Kufa for Mathematics and Computer, 2019
The concept of intuitionistic topological space was introduced by Çoker. The aim of this paper is to generalize notions between bitopological spaces and double topological spaces and also give a notion of pairwise locally compact and compactification ...

On Some Results in Fuzzy Length Space

open access: yesAl-Mustansiriyah Journal of Science, 2020
In this paper, depending on the notion of fuzzy length space we define the Cartesian product of two fuzzy length spaces. we proved that the Cartesian product of two fuzzy length spaces is a fuzzy length space.

Universal properties of group actions on locally compact spaces [PDF]

open access: yes, 2014
We study universal properties of locally compact G-spaces for countable infinite groups G. In particular we consider open invariant subsets of the \beta-compactification of G (which is a G-space in a natural way), and their minimal closed invariant ...
