by R. Cignoli, A. Di Nola A. Lettieri It is shown that the construction and the properties of the functor β from the category of MV-algebras to the category of bounded residuated lattices has a natural interpretation in the contest of Priestley dualities.
In this paper it is shown that the prime ideal space of an MV-algebra is the disjoint union of prime ideal spaces of suitable local MV-algebras. Some special classes of algebras are defined and their spaces are investigated. The space of minimal prime ideals is studied as well.
