Abstract
The fuzzification of pseudo subalgebras/ideals in d-algebras and pseudo BCK-ideals is discussed. Several properties are investigated. Relations between fuzzy pseudo BCK-ideals and fuzzy pseudo d-ideals are established. Conditions for a fuzzy set to be a fuzzy pseudo BCK-ideal are considered. Using the notion of fuzzy points, a general form of fuzzy pseudo d-subalgebras is introduced, and several properties including their characterizations are investigated.
