Łukasiewicz fuzzy ideals in BCK-algebras and BCI-algebras

2023
Summary: The notion of (closed) Łukasiewicz fuzzy ideal is introduced, and several properties are investigated. The relationship between Łukasiewicz fuzzy subalgebra and Łukasiewicz fuzzy ideal is discussed, and characterization of a Łukasiewicz fuzzy ideal is considered. Conditions for a Łukasiewicz fuzzy subalgebra to be a Łukasiewicz fuzzy ideal are

1987
We characterize positive implicative BCK-algebras in the language of left-maps and show that the set of all left-maps of a BCK-algebra X is also a BCK-algebra.
