摘要：We introduce the notion of sensible fuzzy ideals of BCK-algebras
with respect to a t-conorm and investigate some of their
properties. We give the conditions for a sensible fuzzy subalgebra
with respect to a t-conorm to be a sensible fuzzy ideal with
respect to a t-conorm. Some properties of the direct product and
S
-product of fuzzy ideals of BCK-algebras with respect to a
t-conorm are also discussed.
