Several Inequalities of Frechet Spaces [PDF]

open access: yes, 2005
Several inequalities of Frechet spaces are given in this paper, which can be regarded as the Frechet spaces versions of the well-known polarization identity occurring in Hilbert spaces. Our results generalize many inequalities in Banach spaces.

On Characterizations of ∗-Hyperconnected Ideal Topological Spaces

open access: yesJournal of Mathematics, 2020
In the present paper, some characterizations of ∗-hyperconnected ideal topological spaces are investigated. Moreover, we introduce the notion of S∗-ℐ-hyperconnected ideal topological spaces.

Two preservation results for countable products of sequential spaces [PDF]

open access: yes, 2007
We prove two results for the sequential topology on countable products of sequential topological spaces. First we show that a countable product of topological quotients yields a quotient map between the product spaces.

A Study on Continuity functions in Neutro-Topological Spaces [PDF]

open access: yesNeutrosophic Sets and Systems
The specific purpose of this study is to define continuity of mappings in neutro-topological spaces using neutro-open and neutro-closed sets and analyze the properties of continuous functions that are true in classical topological spaces in the neutro ...

On Neutrosophic Crisp Topology via N-Topology [PDF]

open access: yesNeutrosophic Sets and Systems, 2018
In this paper, we extend the neutrosophic crisp topological spaces into N-neutrosophic crisp topological spaces (Nnc-topological space). Moreover, we introduced new types of open and closed sets in N-neutrosophic crisp topological spaces. We also present

Topological Up-Algebras

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
In this paper, we introduce the notion of topological UP-algebras and several types of subsets of topological UP-algebras, and prove the generalization of these subsets.

On some spaces via topological ideals

open access: yesOpen Mathematics, 2023
Our main purpose is to introduce and investigate the concepts of some forms of spaces via topological ideals. Some characterizations of some forms of spaces via topological ideals are established.

Compactly Generated Domain Theory [PDF]

open access: yes, 2006
We propose compactly generated monotone convergence spaces as a well-behaved topological generalisation of directed-complete partial orders (dcpos). The category of such spaces enjoys the usual properties of categories of 'predomains' in denotational ...

α-Topological Vector Spaces

open access: yesScience Journal of University of Zakho, 2017
The main objective of this paper is to present the study of α-topological vector spaces. α-topological vector spaces are defined by using α-open sets and α-irresolute mappings.
