FUZZY SUBALGEBRAS WITH THRESHOLDS IN BCK/BCI-ALGEBRAS Jun, Young-Bae;
Using the belongs to relation () and quasi-coincidence with relation (q) between fuzzy points and fuzzy sets, the concept of ()-fuzzy subalgebras where are any two of with was introduced, and related properties were investigated in . As a continuation of the paper , in this paper, the notion of a fuzzy subalgebra with thresholds is introduced, and its characterizations are obtained. Relations between a fuzzy subalgebra with thresholds and an ()-fuzzy subalgebra are provided.
