Closure properties of function spaces

open access: yesApplied General Topology, 2003
In this paper we investigate some closure properties of the space Ck(X) of continuous real-valued functions on a Tychonoff space X endowed with the compact-open topology.

Axiomatic systems of Alexandrov spaces

open access: yesJournal of Hebei University of Science and Technology, 2017
In order to study internel axiomatic systems and ordered features of Alexandrov spaces, with the help of some existed results in topology and locale theory, by restricting the related structures into Alexandrov setting, some equivalent descriptions are ...

Exchange properties of combinatorial closure spaces [PDF]

open access: yes, 1986
Finite closure spaces with the Steinitz exchange property are characterized and the connection between the Steinitz and the MacLane exchange property and related exchange properties is discussed.

On the Closures of Dirichlet Type Spaces in the Bloch Space

open access: yesComplex Analysis and Operator Theory, 2017
Let $\mathbb{D}$ be the open unit disk in the complex plane, and let $\mathrm{Hol}(\mathbb{D})$ denote the space of holomorphic functions on the unit disk. A function $f\in\mathrm{Hol}(\mathbb{D})$ is said to belong to the Bloch space $\mathcal{B}$ if \[ \|f\|_{\mathcal{B}}=|f(0)|+\sup_{z\in\mathbf{D}}(1-|z|^2)|f^\prime (z)|-1$, the space $\mathcal{D ...

Closure conversion is safe for space [PDF]

open access: yesProceedings of the ACM on Programming Languages, 2019
We formally prove that closure conversion with flat environments for CPS lambda calculus is correct (preserves semantics) and safe for time and space, meaning that produced code preserves the time and space required for the execution of the source program.

A novel topological structure based on closure filter [PDF]

open access: yesMathematics and Computational Sciences
This research explores a closure Filter structure which generates a novel closure Filter topology and defines a new operator that satisfies Kuratowski's closure axioms.

ϱ- TOPOLOGICAL OPERATORS IN TOPOLOGICAL SPACES

open access: yesScience Journal of University of Zakho, 2023
Operation Approach on a new class of topological spaces with -open subsets was called a -open set. In this article, we examined some basic properties of open sets such as closure, , limit points, derived sets, neighbourhood, interior, exterior, boundary,

Interior and closure in anti-minimal and anti-biminimal spaces in the frame of anti-topology [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
The main goal of this project is to analyze the structure of anti-biminimal spaces through the lens of the notions of interior and closure. Anti-biminimal spaces can be considered as generalizations of anti-bitopological spaces that have been introduced ...

Another closure operator on preneighbourhood spaces [PDF]

open access: yesCategories and General Algebraic Structures with Applications
The notions of dense, proper, separated or perfect morphisms and hence of compact, Hausdorff or compact Hausdorff are all consequent to good properties of a family of closed morphisms is well known in literature.
