(d, H)-Equality of Fuzzy Sets
Irina Georgescu
The Cai d-equality of fuzzy sets corresponds to the Lukasiewicz t-norm. In this paper we study the notion of ( H ,d )-equality, a concept which generalizes the d-equality to the case of the fuzzy set theory based on an arbitrary continuous t-norm H. We investigate the robustness of some fuzzy implication operators in terms of ( H ,d )-equality.
