Abstract

The main purpose of this paper is to generalize the concept of (L,M)-fuzzy @s-algebras defined by Shi [F.G. Shi, (L,M)-fuzzy @s-algebras, International Journal of Mathematics and Mathematical Sciences. doi:10.1155/2010/356581] from L-fuzzy sets to intuitionistic fuzzy sets; the notions of L-intuitionistic fuzzy @s-algebras and L-intuitionistic fuzzy measurable functions are introduced; the relationships among L-intuitionistic fuzzy @s-algebras, (I,I)-fuzzy @s-algebras and I-fuzzifying @s-algebras are studied. Then we give the definition of the product of L-intuitionistic fuzzy @s-algebras; some of their elementary properties are discussed. By use of the concept of I-fuzzifying @s-algebras, the notion of generated L-intuitionistic fuzzy @s-algebras is proposed. Finally, the properties of the generated functor I@z from the category of I-fuzzifying @s-algebras and I-fuzzifying measurable functions to the category of L-intuitionistic fuzzy @s-algebras and L-intuitionistic fuzzy measurable functions are proved.
