Cubic rational expressions over a finite field

  title={Cubic rational expressions over a finite field},
  author={Sandro Mattarei and Marco Pizzato},
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. 


Finite subgroups of PGL(2,K)
We classify, up to conjugacy, the finite subgroups of PGL2(K) of order prime to char(K).

Some Problems Concerning Polynomials over Finite Fields, or Algebraic Divertissements
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.
Rational functions with given ramification in characteristic p
Using limit linear series and a result controlling degeneration from separable maps to inseparable maps, we give a formula for the number of rational functions (up to automorphism of the target) on
The Arithmetic of Elliptic Curves
This research focuses on 9 specific elliptic curves E over Q, each with complex multiplication by the maximal order in an imaginary quadratic field, defined by the generators ω1, ω2 ∈ C of the period lattice.

The Probability of Relatively Prime Polynomials
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
