The Distributivity of Extended Operations on Fuzzy Truth Values
Zhi-Qiang Liu and Xue-Ping Wang
In this paper we give necessary and sufficient conditions for the distributivity of extended operations on fuzzy truth values. Applications are given to the distributivity problem of extended t-norms and t-conorms.
