Orbits of Second Order Linear Recurrences over Finite Fields

Chatchawan Panraksa, Naveen Somasunderam

Let $Q$ be the matrix $(a 1 b 0)$ in $G L_{2} (F_{q})$ where $F_{q}$ is a finite field, and let $G$ be the finite cyclic…

A dynamical system proof of Niven's theorem and its extensions

Chatchawan Panraksa, Detchat Samart, Songpon Sriwongsa

Niven's theorem asserts that ${cos (r π) ∣ r \in Q} \cap Q = {0, \pm 1, \pm 1/2} .$ In this paper, we use elementary techniques and results from arithmetic dynamic…

A Note on Average of Roots of Unity

Chatchawan Panraksa, Pornrat Ruengrot

We consider the problem of characterizing all functions $f$ defined on the set of integers modulo $n$ with the property that an average of some $n$ th roots of unity determined by $…
