Resumen
- In a previous paper we have studied two classes of fuzzy bi-implications based on t-norms and r-implications, and shown that they constitute increasingly weaker subclasses of the Fodor-Roubens bi-implication. Now we prove that each of these three classes of bi-implications is closed under automorphisms.
