1795. Olga Kharlampovich and Christopher Natoli On countable elementary free groups E-mail: Submission date: 3 June 2020 Abstract: We prove that if a countable group is elementarily equivalent to a non-abelian free group and all of its finitely generated abelian subgroups are cyclic, then the group is a union of a chain of regular NTQ groups (i.e., hyperbolic towers).
