Expanding Pythagorean fuzzy sets with distinctive radii: disc Pythagorean fuzzy sets

Complex & Intelligent Systems, 2023
This article presents the circular Pythagorean fuzzy set (C-PFS) model, a generalization of the circular intuitionistic fuzzy set model that improves its performance thanks to the acclaimed extension of intuitionistic fuzzy sets to Pythagorean fuzzy sets.

(inf, sup)-Hesitant Fuzzy Ideals of BCK/BCI-Algebras

International Journal of Analysis and Applications, 2022
In this paper, we introduce the concept of (inf, sup)-hesitant fuzzy ideals, which is a generalization of the concept of interval-valued fuzzy ideals, in BCK/BCI-algebras and its related properties are investigated. The concept is established in terms of
