Departing from a twist–structure representation for De Morgan algebras, we construct an structure with more axes (2n + 2 axes actually) that shows to represent the Moisil operators more efficiently. With this representation, the theory of homomorphisms, filters and free algebras is simplified significantly. Finally, we complete this study with the presentation of a logic sound and complete with these new models.</p> <p><strong>MSC (2010):</strong> Primary 06D35, Secondary 03B60.</p> <p><strong>Key words:</strong> many valued logics, twist structures, Lukasiewicz–Moisil algebras.</p> Manuel Fidel, Martı́n Figallo ##submission.copyrightStatement## Wed, 20 Dec 2017 00:00:00 -0200
