Subtraction algebras and $BCK$-algebras [PDF]
Mathematica Bohemica, 2003 Summary: In this note we show that a subtraction algebra is equivalent to an implicative BCK-algebra, and a subtraction semigroup is a special case of a BCI-semigroup.

Cubic Pythagorean Fuzzy Graphs
Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022 The purpose of the study is to explore graph theory based on cubic Pythagorean fuzzy sets. The concept of cubic Pythagorean fuzzy graphs (CuPFGs) is introduced in this research work. In addition, we define certain fundamental operations on CuPFGs including semistrong product, lexicographical product, and symmetric difference of two CuPFGs and ...

Pure submodules of BCK-modules [PDF]
Journal of Hyperstructures, 2014 In this paper by considering the notion of BCK-module, we introduce pure BCK- submodules and we prove some results by it. In particular, we show that if X is a BCK- algebra, M is a cyclic BCK-module and N a prime BCK- submodule of M, then N is a pure BCK-

Some Results about Weak UP‐algebras
Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022 We introduce a new class of algebras, weak UP‐algebras, briefly written as WUP‐algebras, as a wider class than the classes of UP‐algebras and KU‐algebras. We investigate fundamental aspects including maximal elements, branches and the subalgebra consisting of maximal elements of a WUP‐algebra.

Algebraic Properties of (ω, θ)‐Complex Fuzzy Subgroups
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 This paper defined the notion of (ω, θ)‐complex fuzzy sets, (ω, θ)‐complex fuzzy subgroupoid, and (ω, θ)‐complex fuzzy subgroups and described important examples under (ω, θ)‐complex fuzzy sets. Additionally, we discussed the conjugacy class of group with respect to (ω, θ)‐complex fuzzy normal subgroups.

Kannan Nonexpansive Operators on Variable Exponent Cesàro Sequence Space of Fuzzy Functions
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 In general, we have constructed the operator ideal generated by extended s‐fuzzy numbers and a certain space of sequences of fuzzy numbers. An investigation into the conditions sufficient for variable exponent Cesàro sequence space of fuzzy functions furnished with the definite function to create pre‐quasi‐Banach and closed is carried out.

Interval Valued m-polar Fuzzy BCK/BCI-Algebras
International Journal of Computational Intelligence Systems, 2021 The notion of interval-valued m-polar fuzzy sets (abbreviated IVmPF) is much wider than the notion of m-polar fuzzy sets. In this paper, we apply the theory of IVmPF on BCK/BCI-algebras.

Fuzzy Set Theoretic Approach to Generalized Ideals in BCK/BCI-Algebras
Journal of Function Spaces, 2022 This paper deals with the study of generalizations of fuzzy subalgebras and fuzzy ideals in BCK/BCI-algebras. In fact, the notions of ∈,∈∨κ~∗,qκ~-fuzzy subalgebras, ∈,∈∨κ~∗,qκ~-fuzzy ideals, and ∈∨κ~∗,qκ~,∈∨κ~∗,qκ~-fuzzy ideals in BCK/BCI-algebras are ...
