We extend de Finetti’s No-Dutch-Book Criterion to Gödel infinite-valued propositional logic.

We extend de Finetti's No-Dutch-Book Criterion to Gödel infinite-valued propositional logic.

We axiomatize the notion of state over finitely generated free NM-algebras, the Lindenbaum algebras of pure Nilpotent Minimum logic. We show that states over the free n -generated NM-algebra exactly correspond to integrals of elements of with respect to Borel probability measures.

Gödel algebras form the locally finite variety of Heyting algebras satisfying the prelinearity axiom =. In 1969, Horn proved that a Heyting algebra is a Gödel algebra if and only if its set of prime filters partially ordered by reverse inclusion–i.e. its prime spectrum–is a forest. Our main result characterizes Gödel algebras that are free over some finite distributive lattice by an intrisic property of their spectral forest.

In this paper we give a representation of the free MV-algebra over one generator as a structure of functions having finite domain.
