A Novel Decision-Making Approach under Complex Pythagorean Fuzzy Environment
Mathematical and Computational Applications, 2019 A complex Pythagorean fuzzy set (CPFS) is an extension of a Pythagorean fuzzy set that is used to handle the vagueness with the degrees whose ranges are enlarged from real to complex subset with unit disc.

Decision-Making Approach under Pythagorean Fuzzy Yager Weighted Operators
Mathematics, 2020 In fuzzy set theory, t-norms and t-conorms are fundamental binary operators. Yager proposed respective parametric families of both t-norms and t-conorms. In this paper, we apply these operators for the analysis of Pythagorean fuzzy sets. For this purpose,

Pythagorean Fuzzy Digraphs and Its Application in Healthcare Center
Journal of Mathematics, 2021 The notion of fuzzy set is introduced to deal with uncertainty, whereas the conventional sets are used for certainty. The extensions of fuzzy set theory such as intuitionistic fuzzy set (IFS) and Pythagorean fuzzy sets (PyFS) were introduced to overcome ...

Information, 2018 As a generalization of the intuitionistic fuzzy set (IFS), a Pythagorean fuzzy set has more flexibility than IFS in expressing uncertainty and fuzziness in the process of multiple criteria group decision-making (MCGDM). Meanwhile, the prominent advantage

Journal of Intelligent Systems, 2018 In this paper, we introduce the concept of the Pythagorean hesitant fuzzy set (PHFS), which is the generalization of the intuitionistic hesitant fuzzy set under the restriction that the square sum of its membership degrees is ≤1.

A new similarity measure for Pythagorean fuzzy sets [PDF]
Complex & Intelligent Systems, 2019 One of the methods of studying on two sets is to calculate the similarity of two sets. Triangular norms and conorms generalize the basic connectives between fuzzy sets, intuitionistic fuzzy sets, Pythagorean fuzzy sets. In this paper we used triangular conorms (S-norm).

Rough Pythagorean Fuzzy Sets in UP-Algebras
European Journal of Pure and Applied Mathematics, 2022 This paper aims to apply the concept of rough sets to Pythagorean fuzzy sets in UP-algebras. Then we introduce fifteen types of rough Pythagorean fuzzy sets in UP-algebras and study their generalization. In addition, we will also discuss $t$-level subsets of rough Pythagorean fuzzy sets in UP-algebras to study the relationships between rough ...
