When is the space of semi-additive functionals an absolute (neighbourhood) retract?

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2022
In the present paper proved that if for a given compact Hausdorff space X the hyperspace exp(X) is a contractible compact space then the space OSf(X) is also a contractible compact space.

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.

H-Compact Space

open access: yesJournal of Kufa for Mathematics and Computer, 2011
Using the concept of H-open set, we introduce the concept of H-compact space. Several properties of H-compact spaces are proved , among these are: • H-closed subset of H-compact is      H-compact.

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.

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.

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.

Quantum stochastic convolution cocycles II [PDF]

open access: yes, 2008
Schurmann's theory of quantum Levy processes, and more generally the theory of quantum stochastic convolution cocycles, is extended to the topological context of compact quantum groups and operator space coalgebras.

Compact routing on the Internet AS-graph [PDF]

open access: yes, 2011
Compact routing algorithms have been presented as candidates for scalable routing in the future Internet, achieving near-shortest path routing with considerably less forwarding state than the Border Gateway Protocol.
