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.

Cycle spaces in topological spaces [PDF]

open access: yesJournal of Graph Theory, 2008
AbstractWe develop a general model of edge spaces in order to generalize, unify, and simplify previous work on cycle spaces of infinite graphs. We give simple topological criteria to show that the fundamental cycles of a (generalization of a) spanning tree generate the cycle space in a connected, compact, weakly Hausdorff edge space.

On generalized topological molecular lattices [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
In this paper, we introduce the concept of the generalized topological molecular lattices as a generalization of Wang's topological molecular lattices,  topological spaces, fuzzy topological spaces, L-fuzzy topological spaces and soft topological spaces.

The Ingenuity of Neutrosophic Topology via N-Topology [PDF]

open access: yesNeutrosophic Sets and Systems, 2018
In this paper we desire to extend the neutrosophic topological spaces into N-neutrosophic topological spaces. Also we show that this theory can be deduced to N-intuitionistic and N-fuzzy topological spaces etc.

Convergence Classes of L-Filters in L,M-Fuzzy Topological Spaces

open access: yesJournal of Mathematics, 2021
An L,M-fuzzy topological convergence structure on a set X is a mapping which defines a degree in M for any L-filter (of crisp degree) on X to be convergent to a molecule in LX.

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.

Neutrosophic Vague Topological Spaces [PDF]

open access: yesNeutrosophic Sets and Systems, 2019
The term topology was introduced by Johann Beredict Listing in the 19th century. Closed sets are fundamental objects in a topological space. In this paper, we use neutrosophic vague sets and topological spaces and we construct and develop a new concept

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.
