Neutrosophic Nano Semi-Frontier [PDF]

Neutrosophic Sets and Systems, 2020
Smarandache presented and built up the new idea of Neutrosophic set from the Intuition istic fuzzy sets. A.A. Salama presented Neutrosophic topological spaces by utilizing the Neutro sophic sets.

The topological fundamental group and free topological groups [PDF]

, 2010
The topological fundamental group $\pi_{1}^{top}$ is a homotopy invariant finer than the usual fundamental group. It assigns to each space a quasitopological group and is discrete on spaces which admit universal covers.

Reduced Coproducts of Compact Hausdorff Spaces [PDF]

, 1987
By analyzing how one obtains the Stone space of the reduced product of an indexed collection of Boolean algebras from the Stone spaces of those algebras, we derive a topological construction, the reduced coproduct , which makes sense for indexed ...

Nearly Soft Menger Spaces

Journal of Mathematics, 2020
In this paper, we define a weak type of soft Menger spaces, namely, nearly soft Menger spaces. We give their complete description using soft s-regular open covers and prove that they coincide with soft Menger spaces in the class of soft regular⋆ spaces ...

Strictly convex norms and topology

, 2010
We introduce a new topological property called (*) and the corresponding class of topological spaces, which includes spaces with $G_\delta$-diagonals and Gruenhage spaces.

On separating axioms and similarity of soft topological spaces

Soft Computing - A Fusion of Foundations, Methodologies and Applications, 2019
We will consider soft topologies defined on the same universe X with E as the set of parameters. It is shown that soft topologies are not equivalent to the general topologies defined on X.

The Rice-Shapiro theorem in Computable Topology

, 2017
We provide requirements on effectively enumerable topological spaces which guarantee that the Rice-Shapiro theorem holds for the computable elements of these spaces.

On the Weight of a Topological Space [PDF]

Proceedings of the American Mathematical Society, 1974
The main result in this paper states that the weight of a regular space is the product of three cardinal functions, namely the Lindelöf degree, the pluming degree, and the point separating weight.

N-Closure and N-Interior in Neutrosophic Topological Spaces

Neutrosophic Sets and Systems
Topology greatly benefits from the concept of δ-cloure. Its quiet nature to extended its proper-ties in other topological spaces. So, with the concept of quasi-coincidence Ganguly and Saha pioneered and extensively examined the notion of δ-closure ...
