Two theorems for intuitionistic fuzzy sets
The paper deals with intuitionistic fuzzy sets, which are characterized by two functions expressing the degree of membership and the degree of non-membership of an element of the universe of the fuzzy set. Both functions take values in the interval \([0,1]\) and their sum is not greater than 1. The main results characterise the relation between some operators over the intuitionistic fuzzy sets.
