Formal solutions and the first‐order theory of acylindrically hyperbolic groups

S André, J Fruchter - Journal of the London Mathematical …, 2022 - Wiley Online Library
We generalise Merzlyakov's theorem about the first‐order theory of non‐abelian free groups
to all acylindrically hyperbolic groups. As a corollary, we deduce that if GG is an …

In this paper we study the elementary theory of graph products of groups and show that
under natural conditions on the vertex groups we can recover (the core of) the underlying …
