On soft topological space via semiopen and semiclosed soft sets [PDF]

, 2012
This paper introduces semiopen and semiclosed soft sets in soft topological spaces. The notions of interior and closure are generalized using these sets.

Relative Smooth Topological Spaces

Advances in Fuzzy Systems, 2009
In 1992, Ramadan introduced the concept of a smooth topological space and relativeness between smooth topological space and fuzzy topological space in Chang's (1968) view points. In this paper we give a new definition of smooth topological space.

Topological Rough Groups

Topological Algebra and its Applications, 2016
The concept of topological group is a simple combination of the concepts of abstract group and topological space. The purpose of this paper is to combine the concepts of topological space and rough groups; called topological rough groups on an ...

GTI-space : the space of generalized topological indices [PDF]

, 2008
A new extension of the generalized topological indices (GTI) approach is carried out torepresent 'simple' and 'composite' topological indices (TIs) in an unified way.

Closed subsets of compact-like topological spaces

Applied General Topology, 2020
We investigate closed subsets (subsemigroups, resp.) of compact-like topological spaces (semigroups, resp.). We show that each Hausdorff topological space is a closed subspace of some Hausdorff ω-bounded pracompact topological space and describe open ...

Door spaces on N-topology

Ratio Mathematica, 2023
In this article, we explore the idea of door space on -topological space. Here, we discuss which door spaces in this space are related with  submaximal. The equivalent conditions shows how it connects a -topological property. Also, we derive various door

The character of free topological groups I

Applied General Topology, 2005
A systematic analysis is made of the character of the free and free abelian topological groups on uniform spaces and on topological spaces. In the case of the free abelian topological group on a uniform space, expressions are given for the character in ...

Z2-topology in nonsymmorphic crystalline insulators: Mobius twist in surface states [PDF]

, 2015
It has been known that an anti-unitary symmetry such as time-reversal or charge conjugation is needed to realize Z2 topological phases in non-interacting systems. Topological insulators and superconducting nanowires are representative examples of such Z2

Magnetic topological quantum chemistry [PDF]

Nature Communications, 2020
For over 100 years, the group-theoretic characterization of crystalline solids has provided the foundational language for diverse problems in physics and chemistry.

A Hybrid Approach to Micro Vague Topological Space via Neutrosophic Topological Space [PDF]

Neutrosophic Sets and Systems
Plenty of topologists are exploring and discovering multiple forms of topological spaces. The chief objective of the current enquiry is to establish and evaluate an original hybrid topological space named Neutrosophic Micro Vague Topological Space. When
