en عمومى General پژوهشي Research paper <p>Using the notion of anti fuzzy points and its besideness to and non-quasi-coincidence with a fuzzy set, new concepts of an anti fuzzy subalgebras in BCK/BCI-algebras are introduced and their inter-relations and related properties are investigated in [3]. The notion of the new fuzzy subalgebra with thresholds are introduced and relationship between this notion and the new fuzzy subalgebra of a BCK/BCI-algebra of [3] are studied.</p> besides to, non-quasi coincident with, (α, β)∗-fuzzy subalgebra, fuzzy subalgebra with thresholds, fuzzifying subalgebra, t-implication-based subalgebra. 9 24 http://ijmsi.ir/browse.php?a_code=A-10-1-72&slc_lang=en&sid=1 Arsham Borumand Saeid 10031947532846002110 10031947532846002110 Yes
