On denominators of consecutive $SL (2, N)$ -saturated Farey fractions

Jack Anderson, Florin P. Boca, Cristian Cobeli +1

The sequence $(S_{Q})_{Q}$ of $SL (2, N)$ -saturated Farey fractions was defined in our previous work by ${\mathscr S}_Q := \{ a/q \in {\mathbb Q} \cap…

On the distribution of $SL (2, N)$ -saturated Farey fractions

Jack Anderson, Florin P. Boca, Cristian Cobeli +1

We consider the set $S_{Q}$ of Farey fractions $d / b$ of order $Q$ with the property that there exists a matrix $\left( \begin{smallmatrix} a & b \\ c & d \end{smallmatrix}…

Angular distribution towards the points of the neighbor-flips modular curve seen by a fast moving observer

Jack Anderson, Florin P. Boca, Cristian Cobeli +1

Let $h$ be a fixed non-zero integer. For every $t \in R_{+}$ and every prime $p$ , consider the angles between rays from an observer located at the point $(- t J_{p}^{2}, 0)$ on the…
