Fuzzy Foldness of Ideals in BCK / BCI ��� Algebras

The study of BCK/BCI-algebras was initiated by Iséki to generalize the concept of set-theoretic difference and propositional calculus. Since then a great deal of theorems has been produced on the theory of BCK/BCI-algebras. In(1965) Zadeh has introduced the notion of a fuzzy subset of a set as a method for representing uncertainty. In 1991 Xi defined fuzzy subsets in BCK/BCI-algebras. In 2020Muhiuddin and Jun gave Further Results of Neutrosophic subalgebras in BCK/BCI -algebras based on Neutrosophic points. In 2019 Muhiuddin Kim and Jun defined Implicative N – ideals of BCK – algebras based on Neutrosophic N – structures.
