Abstract
This paper introduces a new construction of fuzzy topology on BCK-algebras
based on the notion of fuzzy ideals. By defining a fuzzy neighborhood system derived
from all fuzzy ideals that assign full membership to a given point, we construct a fuzzy
topological structure on a BCK-algebra (X, ∗, 0). A fuzzy set is declared open if it satisfies
a continuity-like condition with respect to this neighborhood system. We establish
fundamental properties of this topology, including the behavior of fuzzy open sets, the
relationship between fuzzy ideals and neighborhoods, and several structural theorems.
This work generalizes earlier approaches to topologizing algebraic structures using ideals
in the fuzzy setting and provides a framework for further exploration in fuzzy logical
algebras.
