Expansion in $SL_{2} (Z / q Z)$ and Zaremba's conjecture

Xin Zhang

We establish an expansion theory for $SL_{2} (Z / q Z)$ . Incorporating this into a framework recently developed by Shkredov, we confirm Zaremba's conjecture.

On Representation of Integers from Thin Subgroups of SL(2,Z) with Parabolics

Xin Zhang

Let $Λ < S L (2, Z)$ be a finitely generated, non-elementary Fuchsian group of the second kind, and $v, w$ be two primitive vectors in $Z^{2} - (0, 0)$ . We consider the set…
