The logical complexity of finitely generated commutative rings

Logic 2016-10-18 v1 Commutative Algebra

Abstract

We characterize those finitely generated commutative rings which are (parametrically) bi-interpretable with arithmetic: a finitely generated commutative ring AA is bi-interpretable with (N,+,×)(\mathbb N,{+},{\times}) if and only if the space of non-maximal prime ideals of AA is nonempty and connected in the Zariski topology and the nilradical of AA has a nontrivial annihilator in Z\mathbb Z. Notably, by constructing a nontrivial derivation on a nonstandard model of arithmetic we show that the ring of dual numbers over Z\mathbb Z is not bi-interpretable with N\mathbb N.
