Multiplicative and Exponential Variations of Orthomorphisms of Cyclic Groups

Evan Chen

An orthomorphism is a permutation $I ¨ $ of ${1, \dots, n - 1}$ for which $x + I ¨ (x) mod n$ is also a permutation on ${1, \dots, n - 1}$ . Eberhard, Manners, MrazoviÄ, showed that t…

Avoiding algebraic integers of bounded house in orbits of rational functions over cyclotomic closures

Evan Chen

Let $k$ be a number field with cyclotomic closure $k^{cyc}$ , and let $h \in k^{cyc} (x)$ . For $A \geq 1$ a real number, we show that \[ \{ Î±\in k^{\mathrm{cyc}} :…
