On countable connected Hausdorff spaces in which the intersection of every pair of connected subsets in connected

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
We prove that a countable connected Hausdorff space in which the intersection of every pair of connected subsets is connected, cannot be locally connected, and also that every continuous function from a countable connected, locally connected Hausdorff ...

Compactifications of Hausdorff Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1969
1. Introduction. In this paper, we describe methods of imbedding a Hausdorff space X in a compact space X so that each function in a given family of continuous functions on X has a continuous extension to X and the family of extensions separates the points of X -X. In particular, if X is completely regular but not locally compact, then we shall exhibit

Compact and extremally disconnected spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
Viglino defined a Hausdorff topological space to be C-compact if each closed subset of the space is an H-set in the sense of Veličko. In this paper, we study the class of Hausdorff spaces characterized by the property that each closed subset is an S-set ...

A Note on Equivalence of G-Cone Metric Spaces and G-Metric Spaces

open access: yesJournal of New Theory, 2023
This paper contains the equivalence between tvs-G cone metric and G-metric using a scalarization function $\zeta_p$, defined over a locally convex Hausdorff topological vector space. This function ensures that most studies on the existence and uniqueness

On nearly Hausdorff compactifications

open access: yesApplied General Topology, 2006
We introduce and study here the notion of nearly Hausdorffness, a separation axiom, stronger than T1 but weaker than T2. For a space X, from a subfamily of the family of nearly Hausdorff spaces, we construct a compact nearly Hausdorff space rX containing

On quasi-orbital space

open access: yesApplied General Topology, 2017
Let G be a subgroup of the group Homeo(E) of homeomorphisms of a Hausdorff topological space E. The class of an orbit O of G  is the union of all orbits having the same closure as O.

Icing Mitigation by MEMS-Fabricated Surface Dielectric Barrier Discharge

open access: yesApplied Sciences, 2021
Avoiding ice accumulation on aerodynamic components is of enormous importance to flight safety. Novel approaches utilizing surface dielectric barrier discharges (SDBDs) are expected to be more efficient and effective than conventional solutions for ...

On a generalization of Hausdorff space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
Here, a new separation axiom as a generalization of that of Hausdorff is introduced. Its simple consequences and relations with some other known separation axioms are studied. That a non-indiscrete topological group satisfies this axiom is shown.

A Simple Proof of Dvoretzky-Type Theorem for Hausdorff Dimension in Doubling Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2022
The ultrametric skeleton theorem [Mendel, Naor 2013] implies, among other things, the following nonlinear Dvoretzky-type theorem for Hausdorff dimension: For any 0 < β < α, any compact metric space X of Hausdorff dimension α contains a subset which is ...

Hausdorff operators on homogeneous spaces of locally compact groups

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2020
Hausdorff operators on the real line and multidimensional Euclidean spaces originated from some classical summation methods. Now it is an active research area. Hausdorff operators on general groups were defined and studied by the author since 2019.
