Abstract: In the paper the so-called dφ-intuitionistic fuzzy set (dφ-IFS), over the non-empty universe E, are considered for the case when dφ is R2-metric induced by an arbitrary fixed absolute normalized R2-norm φ. Using a bijective isomorphism between the class of all such sets and the class of all intuitionistic fuzzy sets over E, any operator acting over one of the mentioned classes produces a similar operator acting on the other. Some of the operators defined over the intuitionistic fuzzy sets and their corresponding similar operators are considered and studied in this paper and important limit theorems are established.
Keywords: Intuitionistic fuzzy set, d-intuitionistic fuzzy set, dφ-intuitionistic fuzzy set, Norm, Absolute norm, Normalized norm, Absolute normalized norm, Similar operator.
