  We connect the dual adjunction between MV-algebras and Tychonoff spaces with
the general theory of natural dualities, and provide a number of applications.
In doing so, we simplify the aforementioned construction by observing that
there is no need of using presentations of MV-algebras in order to obtain the
adjunction. We also provide a description of the dual maps that is
intrinsically geometric, and thus avoids the syntactic notion of definable map.
Finally, we apply these results to better explain the relation between
semisimple tensor products and coproducts of MV-algebras, and we extend beyond
the finitely generated case the characterisations of strongly semisimple and
polyhedral MV-algebras.
