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 ...

A compactification of locally compact spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
Every locally compact space X X has its topology determined by its 1-1 compact images and hence has a compactification

On θ-regular spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
In this paper we study θ-regularity and its relations to other topological properties. We show that the concepts of θ-regularity (Janković, 1985) and point paracompactness (Boyte, 1973) coincide.

Continuous functions with compact support

open access: yesApplied General Topology, 2004
The main aim of this paper is to investigate a subring of the ring of continuous functions on a topological space X with values in a linearly ordered field F equipped with its order topology, namely the ring of continuous functions with compact support ...

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 ...

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.

$L^p$-Conjecture on Hypergroups [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
In this paper, we study $L^p$-conjecture on locally compact hypergroups and by some technical proofs we give some sufficient and necessary conditions  for a weighted Lebesgue space  $L^p(K,w)$ to be a convolution Banach algebra, where ...

A Note on Characteristic Functions [PDF]

open access: yesThe Egyptian Statistical Journal, 1960
In this article, we considered (1.1) a family of proper functions H = (fᵢ) defined in a locally compact-space E and separating its points. The moments of a measure μ on E relative to the proper injection f = (fᵢ) are defined as the integrals μ (eₚ) where

Computably Based Locally Compact Spaces [PDF]

open access: yesLogical Methods in Computer Science, 2006
ASD (Abstract Stone Duality) is a re-axiomatisation of general topology in which the topology on a space is treated, not as an infinitary lattice, but as an exponential object of the same category as the original space, with an associated lambda-calculus.

Compact and stable discontinuous Galerkin methods for convection-diffusion problems [PDF]

open access: yes, 2012
We present a new scheme, the compact discontinuous Galerkin 2 (CDG2) method, for solving nonlinear convection-diffusion problems together with a detailed comparison to other well-accepted DG methods.
