Locally compact space and continuity

open access: yesBibechana, 2010
Topological spaces for being T0, T1, T2 and regular space have been discussed. The conditions for a topological space to be locally compact have also been studied. We have found that a continuous function preserves locally compactness.

On open well-filtered spaces [PDF]

open access: yesLogical Methods in Computer Science, 2020
We introduce and study a new class of $T_0$ spaces, called open well-filtered spaces. The main results we proved include (1) every well-filtered space is an open well-filtered space; (2) every core-compact open well-filtered space is sober.

The Hausdorff Algebra Fuzzy Distance and its Basic Properties [PDF]

open access: yesEngineering and Technology Journal, 2021
In this article we recall the definition of algebra fuzzy metric space and its basic properties. In order to introduced the Hausdorff algebra fuzzy metric from fuzzy compact set to another fuzzy compact set we define the algebra fuzzy distance between ...

A class of spaces containing all generalized absolutely closed (almost compact) spaces

open access: yesApplied General Topology, 2006
The class of θ-compact spaces is introduced which properly contains the class of almost compact (generalized absolutely closed) spaces and is strictly contained in the class of quasicompact spaces.

Tachyons in compact spaces [PDF]

open access: yesJournal of High Energy Physics, 2005
We discuss condensations of closed string tachyons localized in compact spaces. Time evolution of an on-shell condensation is naturally related to the worldsheet RG flow. Some explicit tachyonic compactifications of Type II string theory is considered, and some of them are shown to decay into supersymmetric theories known as the little string theories.

On CSO-Compact Space

open access: yesمجلة بغداد للعلوم, 2008
The aim of this paper is to introduces and study the concept of CSO-compact space via the notation of simply-open sets as well as to investigate their relationship to some well known classes of topological spaces and give some of his properties.

Blackfolds, Plane Waves and Minimal Surfaces [PDF]

open access: yes, 2015
Minimal surfaces in Euclidean space provide examples of possible non-compact horizon geometries and topologies in asymptotically flat space-time. On the other hand, the existence of limiting surfaces in the space-time provides a simple mechanism for ...

A note on Gromov-Hausdorff-Prokhorov distance between (locally) compact measure spaces [PDF]

open access: yes, 2012
We present an extension of the Gromov-Hausdorff metric on the set of compact metric spaces: the Gromov-Hausdorff-Prokhorov metric on the set of compact metric spaces endowed with a finite measure. We then extend it to the non-compact case by describing a

On Compact ∗ Spaces and Compactifications [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
The space β X \beta X of Z Z -ultrafilters on X X with the standard filter space topology is shown to be compact*. Without considering the reflection associated with compact* spaces, we also prove that products of compact* spaces are compact*, in response to a request for a direct ...

Almost periodic mild solutions for stochastic delay functional. differential equations driven by a fractional Brownian motion [PDF]

open access: yesRomanian Journal of Mathematics and Computer Science, 2014
In this paper we investigate the existence and stability of quadratic-mean almost periodic mild solutions to stochastic delay functional differential equations driven by fractional Brownian motion with Hurst parameter H > 1/2 , under some suitable ...
