Character sums over elements of extensions of finite fields with restricted coordinates

Siddharth Iyer, Igor Shparlinski

We obtain nontrivial bounds for character sums with multiplicative and additive characters over finite fields over elements with restricted coordinate expansion. In particular, we…

Counting elements of the congruence subgroup

Kamil Bulinski, Igor E. Shparlinski

We obtain asymptotic formulas for the number of matrices in the congruence subgroup \[ Γ_0(Q) = \left\{ A\in\mathrm{SL}_2(\mathbb Z):~c \equiv 0 \pmod Q\right\}, \] which are of na…
