Cubic rational expressions over a finite field
@inproceedings{Mattarei2021CubicRE, title={Cubic rational expressions over a finite field}, author={Sandro Mattarei and Marco Pizzato}, year={2021} }
We classify the cubic rational expressions g(x)/h(x) over a finite field, having at most three ramification points, under an equivalence relation given by preand post-composition with independent Möbius transformations.

In this thesis we consider some problems concerning polynomials over finite fields.
The first topic is the action of some groups on irreducible polynomials. We describe orbits and stabilizers. …

The one sentence proof is that any number that divides a and b must also divide b and r (since r = a ? qb) and vice versa; hence, the pairs (a, b) and (b, r) have the exact same set of common…
