Pythagorean Nanogeneralized Closed Sets with Application in Decision-Making

Abstract

Topology is studying the objects which are considered to be equal if they may also be continually deformed through other shapes as bending and twisting without tearing or glueing them. Topology is similar in geometrical structures and quantitatively equivalent. Nanotopology is the study of set. The main goal of this article is to propose the idea of generalized closed sets in Pythagorean nanotopological spaces. In addition, the concept of semigeneralized closed sets is also defined, and their properties are investigated. An application to MADM using Pythagorean nanotopology has been proposed and illustrated using a numerical example.

Normal spaces associated with fuzzy nano M -open sets and its application

“…Ramachandran and Stephan Antony Raj [16,17] proposed intuitionistic fuzzy nano topological spaces and extended to generalized closed sets. Ajay and Joseline [1,2] introduced pythagorean nano topological spaces and discussed their properties of pythagorean nanogeneralized closed sets with application in decision-making problem. El-Maghrabi and Al-Juhani [10] proposed the concept of M-open sets in topological spaces in 2011 and examined some of their features.…”
