FUZZY NEUTROSOPHIC PRIME IDEALS OF BCK-ALGEBRAS

Abstract

In this research paper, we introduce and analyze the notion of fuzzy neutrosophic prime ideals (FNPIs) in a commutative BCK-algebra $\mathcal{K}$. It represents a further extension of prime ideals in the context of fuzzy neutrosophic sets. We provide an example that shows that not every fuzzy neutrosophic ideal of a commutative BCK-algebra $\mathcal{K}$ is a FNPI of $\mathcal{K}$. We also prove that a fuzzy neutrosophic set of $\mathcal{K}$ is a FNPI of $\mathcal{K}$ if, for all $a,b,c \in [0,1] $, the upper (a,b)-level cut and lower c-level cut are prime ideals of $\mathcal{K}$.
