Existential rank and essential dimension of diophantine sets
@inproceedings{Daans2021ExistentialRA, title={Existential rank and essential dimension of diophantine sets}, author={Nicolas Daans and Philip Dittmann and Arno Fehm}, year={2021} }
We study the minimal number of existential quantifiers needed to define a diophantine set over a field and relate this number to the essential dimension of the functor of points associated to such a definition.

We show that ${\mathbb Z}$ is definable in ${\mathbb Q}$ by a universal first-order formula in the language of rings. We also present an $\forall\exists$-formula for ${\mathbb Z}$ in ${\mathbb Q}$…

Matijasevic's theorem implies the existence of a diophantine equation U such that for all x and v, x ∈ W v is also recursively enumerable, and the nonexistence of such an algorithm follows immediately from theexistence of r.e. nonrecursive sets.
