On denominators of consecutive -saturated Farey fractions

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

The sequence of -saturated Farey fractions was defined in our previous work by ${\mathscr S}_Q := \{ a/q \in {\mathbb Q} \cap…

Arithmetic Polygons and Sums of Consecutive Squares

Jack Anderson, Amy Woodall, Alexandru Zaharescu

We introduce and study arithmetic polygons. We show that these arithmetic polygons are connected to triples of square pyramidal numbers. For every odd , we prove that there…

Twisted aughts of alternating involutions

Raghavendra N. Bhat, Cristian Cobeli, Shuta Iwai +2

Let be the subgroup of generated by the particular involutions that are identical to the identity, except for a single line where and

On the distribution of -saturated Farey fractions

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

We consider the set of Farey fractions of order 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 be a fixed non-zero integer. For every and every prime , consider the angles between rays from an observer located at the point on the…
