Constructive treatment demonstrates categorical equivalence without subdirect representation in MV-algebras, indicating a new methodology.
Good sequences are central to Mundici’s categorical equivalence between MV-algebras and unital ℓ -groups. We eliminate the reliance on Chang’s subdirect representation theorem traditionally used in the proof, replacing it with an entirely constructive argument based on entailment relations.
