New Types of Topologies and Neutrosophic Topologies (Improved Version) [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
In this paper we recall the six new types of topologies, and their corresponding topological spaces, that we introduced in the last years (2019-20223), such as: NeutroTopology, AntiTopology, Refined Neutrosophic Topology, Refined Neutrosophic Crisp ...

ON bi- INTUITIONSTIC TOPOLOGICAL SPACE

open access: yesTikrit Journal of Pure Science, 2023
In this paper we introduce a new definition is called bi- intuitionistic topological space and from this concept we present some kinds of closed set (semi –closed, pre-closed ,β-closed ,α-closed) setes in bi- intuitionistic topological space, define ...

On the gamma spectrum of multiplication gamma acts

open access: yesKuwait Journal of Science, 2021
In this paper we introduce the concept of topological gamma act as a generalization of Zariski   topology .  Some topological   properties of  this topology   are studied.

Topological Quasilinear Spaces [PDF]

open access: yesAbstract and Applied Analysis, 2012
We introduce, in this work, the notion of topological quasilinear spaces as a generalization of the notion of normed quasilinear spaces defined by Aseev (1986). He introduced a kind of the concept of a quasilinear spaces both including a classical linear spaces and also nonlinear spaces of subsets and multivalued mappings. Further, Aseev presented some

Separation axioms in neutrosophic supra topological space and neutrosophic supra bi-topological space [PDF]

open access: yesNeutrosophic Sets and Systems, 2022
In this paper, as a new separation axioms in neutrosophic supra topological space, NS-Ti- space (i=0,1,2) is built in this space. Moreover, SN.T1T2-open(closed) sets are defined in neutrosophic supra bi-topological spaces. Also SNBi-Ti-space (i=0,1,2) is

Constructions and Properties of Quasi Sigma-Algebra in Topological Measure Space

open access: yesAxioms, 2022
The topological views of a measure space provide deep insights. In this paper, the sigma-set algebraic structure is extended in a Hausdorff topological space based on the locally compactable neighborhood systems without considering strictly (metrized ...

Topological nodal line semimetals in holography

open access: yesJournal of High Energy Physics, 2018
We show a holographic model of a strongly coupled topological nodal line semimetal (NLSM) and find that the NLSM phase could go through a quantum phase transition to a topologically trivial state.

Topological invariants for holographic semimetals

open access: yesJournal of High Energy Physics, 2018
We study the behavior of fermion spectral functions for the holographic topological Weyl and nodal line semimetals. We calculate the topological invariants from the Green functions of both holographic semimetals using the topological Hamiltonian method ...

Countable Fuzzy Topological Space and Countable Fuzzy Topological Vector Space

open access: yesJournal of Mathematical and Fundamental Sciences, 2015
This paper deals with countable fuzzy topological spaces, a generalization of the notion of fuzzy topological spaces. A collection of fuzzy sets F on a universe X forms a countable fuzzy topology if in the definition of a fuzzy topology, the condition of

A New Perspective On Soft Topology

open access: yesHittite Journal of Science and Engineering, 2018
In this paper, we approach the concept of soft topology with a different perspective. We define a soft topological space over given initial topological universe as a parameterization of subspaces of a topological space.
