Some Topological Properties of CbX

open access: yesJournal of Function Spaces, 2014
If X is a completely regular space, first we characterize those spaces CbX whose compact sets are metrizable. Then we use this result to provide a general condition for X to ensure the metrizability of compact sets in CbX.

One point compactification for generalized quotient spaces

open access: yesApplied General Topology, 2010
The concept of Generalized function spaces which were introduced and studied by Zemanian are further generalized as Boehmian spaces or as generalized quotient spaces in the recent literature.

Semi-basic 1-forms and Helmholtz conditions for the inverse problem of the calculus of variations

open access: yes, 2009
We use Fr\"olicher-Nijenhuis theory to obtain global Helmholtz conditions, expressed in terms of a semi-basic 1-form, that characterize when a semispray is locally Lagrangian.

Metrizability of Topology, Precompactness and Semi-Compatibal Mappings in Neutrosophic Metric Spaces [PDF]

open access: yesNeutrosophic Sets and Systems
In this manuscript, we discuss the metrizability of the topology produced by arbitrary neutrosophic metric space. Further, we demonstrate that the resulting topology is completely metrizable if the neutrosophic metric space is complete and a neutrosophic

Extensions defined using bornologies

open access: yesApplied General Topology, 2013
Many extensions of a space X such that the remainder Y is closed can be constructed as B-extensions, that is, by defining a topology on the disjoint union X [ Y , provided there exists a map, satisfying some conditions, from a basis of Y into the family ...

Simultaneous metrizability of coarse spaces

open access: yes, 2011
A metric space can be naturally endowed with both a topology and a coarse structure. We examine the converse to this. Given a topology and a coarse structure we give necessary and sufficient conditions for the existence of a metric giving rise to both of

Some critical remarks on the paper “A note on the metrizability of tvs-cone metric spaces” / Некоторые критические замечания о работе «Заметки о метризуемости твп-конических пространств» / Neke kritičke napomene o radu “Beleška o metrizabilnosti tvp-konusnih metričkih prostora” [PDF]

open access: yesVojnotehnički Glasnik, 2018
This short and concise note provides a detailed exposition of the approach and results established by (Lin et al, 2015, pp.271-279). We show that the obtained results are not particularly surprising and new.

Order-unit-metric spaces

open access: yes, 2013
We study the concept of cone metric space in the context of ordered vector spaces by setting up a general and natural framework for it.Comment: 10 ...
