The framework of the T-spherical fuzzy set is a recent development in fuzzy set theory that
can describe imprecise events using four types of membership grades with no restrictions …

This study focuses on the development and application of Aczel–Alsina (AA) aggregation
operators (AOs) in the context of r, s, t-spherical fuzzy set (SPFS) for multi-criteria decision …

Spherical fermatean interval valued fuzzy soft set is a more well organized, workable and
generalized soft model to deal with uncertainty, as compared to fermatean interval valued …

Uncertainty is the unavoidable part of the life. In almost all circumstances, we regularly find
ourselves in a state of uncertainty. Several reasons can lead to uncertainty, such as …

Fuzzy sets have been widely concerned due it can better deal with more complex and
uncertain problems. To expand the application of fuzzy sets, Yager proposed Pythagorean …

In the present manuscript, a novel concept of T-spherical fuzzy soft set is introduced with
various important operations and properties. In the eld of information theory, an aggregation …

In this article, it is pointed out that the existing intuitionistic fuzzy and T‐spherical fuzzy
Einstein averaging and geometric operators have some limitations. To overcome these …

Spherical fuzzy set (SFS) is a modified version of fuzzy set (FS) to cope with uncertainty and
complicated data in real-decision theory. In this article, some similarity measures, called …

In this paper, we first introduce the concept of T-spherical hesitant fuzzy set (T-SHFS) on the
basis of the combination of T-spherical fuzzy sets (T-SFSs) and hesitant fuzzy sets (HFSs) …

To cope with awkward and unreliable information in daily life issues, the theory of interval‐
valued picture fuzzy set (IVPFS) is a useful idea to manage unpredictable and vague …
