On β*-supra topological spaces

Journal of Discrete Mathematical Sciences & Cryptography, 2023
In this paper, a new type of supra closed sets is introduced which we called supra β*-closed sets in a supra topological space. A new set of separation axioms is defined, and its many properties are examined. The relationships between supra β*-Ti –spaces

On - continuous in topological spaces of neutrosophy

Journal of Interdisciplinary Mathematics, 2021
This paper mainly focuses on incorporating the idea of continuous functions in neutrosophic topological spaces. We are also studying their features and looking at their properties.

Triangulating topological spaces

Proceedings of the tenth annual symposium on Computational geometry - SCG '94, 1994
Given a subspace [Formula: see text] and a finite set S⊆ℝd, we introduce the Delaunay complex, [Formula: see text], restricted by [Formula: see text]. Its simplices are spanned by subsets T⊆S for which the common intersection of Voronoi cells meets [Formula: see text] in a non-empty set. By the nerve theorem, [Formula: see text] and [Formula: see text]

Ultracomplete Topological Spaces

Acta Mathematica Hungarica, 2001
If \(X\) is a set and \(\Sigma\) is a set of coverings of \(X\), then we can consider \((X,\Sigma)\) to be a generalized uniform space. This point of view originates from the work of \textit{J. W. Tukey} [Convergence and uniformity in topology, Princeton (1940)] who used \((X,\Sigma)\), where \(\Sigma\) fulfills some appropriate conditions, as another ...

A model of a human heart via graph nano topological spaces

International Journal of Biomathematics, 2019
In this paper, new forms of nano topological spaces through a neighborhood system of vertices for a digraph will be presented and studied. We apply the connection between digraph theory and nano topological spaces in the human heart as an example in real

Topological Shift Spaces

advg, 2005
Abstract Two of the problems listed in [14, 74.17] ask to prove or disprove the following statements: A) For each differentiable planar map ƒ : IR2 → IR2 the set of all differentials defines a ...

Topology and Topological Spaces

1997
We have now seen four different proofs of the Fundamental Theorem of Algebra. The first two were purely analysis, while the second pair involved a wide collection of algebraic ideas. However, we should realize that even in these algebraic proofs we did not totally leave analysis.

Topological spaces

1994
Abstract The purpose of this chapter is to provide the theoretical background for a rigorous discussion of knots and surfaces, against which the vaguely expressed ideas lying behind our previous discussion can be made precise. The central notion is that of a topological space.
