Pythagorean m-polar Fuzzy Neutrosophic Topology with Applications
Keywords:Pythagorean m-polar fuzzy neutrosophic set, Pythagorean m-polar fuzzy neutrosophic topology, TOPSIS; COVID-19
The overarching structures like intuitionistic fuzzy sets, Pythagorean fuzzy sets, m-polar fuzzy sets, and neutrosophic fuzzy sets etc. have their own inadequacies and impediments. These models are unable to do work because of their impediments in many real life situations. To overcome these deficiencies, in this paper, we introduce a set entitled Pythagorean m-polar fuzzy neutrosophic set (PmFNS), as a hybrid model of Pythagorean fuzzy set, m-polar fuzzy set and single-valued neutrosophic set. We define some notions related to PmFNS with the help of illustrations. We also present some concept of Pythagorean m-polar fuzzy neutrosophic topology alongside its leading characteristics. We render two applications of PmFNS of scarcity of water and
uplifting economy ruined due to COVID-19 using TOPSIS.
