On the reversibility of uninorms and t-operators (Q1867639)

The paper deals with the concept of reverse for t-norms and their extension with some other associative operators, e.g., t-conorms, uninorms and t-operators. The main results characterize all continuous and reversible t-conorms, semi-continuous reversible uninorms, and all continuous reversible t-operators. Moreover, it is shown that the reversibility becomes a kind of transformation converting uninorms into t-operators and vice versa. The moderate growth of uninorms and t-operators is investigated as well.
