First-order sentences in random groups II: $\forall\exists$-sentences

Logic 2022-12-23 v1 Group Theory

Abstract

We prove that a random group, in Gromov's density model with d<1/16d < 1/16 satisfies with overwhelming probability a universal-existential first-order sentence σ\sigma (in the language of groups) if and only if σ\sigma is true in a nonabelian free group.
