Natural dualities for varieties generated by finite positive MV-chains (2309.16998v2)
Published 29 Sep 2023 in math.RA and math.LO
Abstract: We provide a simple natural duality for the varieties generated by the negation- and implication- free reduct of a finite MV-chain. We study these varieties through the dual equivalence thus obtained. For example, we fully characterize their algebraically closed, existentially closed and injective members. We also explore the relationship between this natural duality and Priestley duality in terms of distributive skeletons and Priestley powers.
