Abstract: If $$\Gamma $$Γ is an irreducible non-uniform higher-rank characteristic zero arithmetic lattice (for example $${{\,\mathrm{SL}\,}}_n({\mathbb {Z}})$$SLn(Z), $$n \ge 3$$n≥3) and $$\Lambda $$Λ is a finitely generated group that is elementarily equivalent to $$\Gamma $$Γ, then… read more here.
