Super-approximation, II: the p-adic and bounded power of square-free integers cases

Alireza Salehi Golsefidy

Let $Ω$ be a finite symmetric subset of GL $_{n} (Z [1/ q_{0}])$ , and $Γ := ⟨ Ω ⟩$ . Then the family of Cayley graphs ${Cay (π_{m} (Γ), π_{m} (Ω))}_{m}$ is a family of expan…

Super-approximation, I: p-adic semisimple case

Alireza Salehi Golsefidy

Let $k$ be a number field, $Ω$ be a finite symmetric subset of $GL_{n_{0}} (k)$ , and $Γ = ⟨ Ω ⟩$ . Let \[ C(Γ):=\{\mathfrak{p}\in V_f(k)|\hspace{1mm} Γ\text{is a boun…
