Probing the mass-loss history of AGB and red supergiant stars from CO rotational line profiles - II. CO line survey of evolved stars: derivation of mass-loss rate formulae [PDF]

, 2010
We aim to (1) set up simple and general analytical expressions to estimate mass-loss rates of evolved stars, and (2) from those calculate estimates for the mass-loss rates of asymptotic giant branch (AGB), red supergiant (RSG), and yellow hypergiant ...

On Interval-Valued Intuitionistic Fuzzy Hyper BCK-Ideals of Hyper BCK Algebras [PDF]

, 2014
In this paper, we apply the concept of an interval-valued intuitionistic fuzzy set to hyper BCK-ideals in hyper BCK-algebras. The notion of an interval-valued intuitionistic fuzzification of (strong, weak, s-weak) hyper BCK-ideals is introduced,

Intuitionistic Fuzzy Soft Hyper BCK Algebras

Symmetry, 2019
Maji et al. introduced the concept of fuzzy soft sets as a generalization of the standard soft sets, and presented an application of fuzzy soft sets in a decision-making problem. Maji et al. also introduced the notion of intuitionistic fuzzy soft sets in

BCI/BCK- quantum algebra [PDF]

, 2021
The paper contains an investigation of the notion of BCI-algebras and BCK-algebras. The concept of quantale was created in 1984 to develop a framework for non-commutative spaces and quantum mechanics with a view toward non-commutative logic ...

Dual commutative hyper-K-idelas of type 1 in hyper K-algebras of order 3 [PDF]

, 2006
In this note we classify the bounded hyper K-algebras of order 3, which have D1 = {1}, D2 = {1, 2} and D3 = {0, 1} as a dual commutative hyper K-ideal of type 1.

Hyper Brk-Algebras [PDF]

, 2021
In this article, BRK-Algebras presents the idea of hyper structure and some related properties are discussed.  In addition, we present the concept of the hyper BRK-ideal of a hyper BRK-algebra. A few characteristics are obtained.

Some results on commutative BI-Algebras‎ [PDF]

, 2023
‎The notion of a (branchwise) commutative $BI$-algebra is presented, and some related properties are investigated. We show that the class of commutative $BH$-algebras is broader than the class of commutative $BI$-algebras.

On hyper BI-algebras

, 2021
In this paper, we introduce the notion of hyper BI-algebra and investigate some properties of it. Also, we state and prove some theorems which determine the relationship among $R/ C/ D/ T$ and V-hyper BI-algebras under some conditions.

New Type of Soft (Prime) Ideals in Commutative BCK-Algebras [PDF]

, 2022
The soft set theory is an important mathematical tool for dealing with uncertainty. By endowing a par-ameter set as a commutative BCK-algebra (that is commutative weak-BCI-algebra), the notions of a new type of soft prime ideals, annihilators of soft ...
