A criterion for sharpness of the Elekes-Szabó theorem in positive characteristic

Lucas Nistor
(École Normale Supérieure )
Abstract

We establish that a criterion based on ring-theoretic amenability is both necessary and sufficient for the abelian version of the Elekes-Szabó theorem to be sharp in the case of positive characteristic. Moreover, the criterion is always sufficient. We provide illustrative examples in the theories ACF_p and DCF_0.
