چکیده

Research supported by the Natural Sciences and Engineering Research Council (Canada) and Fonds pour la Formation de Chercheurs et l'Aide a la Recherche (Qu ebec). The algebraic number fields of degree 6 having Galois group S5 and minimum discriminant are determined for signatures (0, 3), (2, 2) and (6, 0). The fields F0, F2, F6 are generated by roots of f0(t) = t 6 + 3t + 2t + 6t + 1, f2(t) = t 6 2t + 12t 16t + 8, and f6(t) = t 6 18t + 9t + 90t 70t 69 respectively. Each of these fields is unique up to isomorphism. This completes the enumeration of primitive sextic fields with minimum discriminant for all possible combinations of Galois group and signature.

5-stars of Low Weight in Normal Plane Maps with Minimum Degree 5

It is known that there are normal plane maps M5 with minimum degree 5 such that the minimum degree-sum w(S5) of 5-stars at 5-vertices is arbitrarily large. In 1940, Lebesgue showed that if an M5 has no 4-stars of cyclic type (5, 6, 6, 5) centered at 5-vertices, then w(S5) ≤ 68. We improve this bound of 68 to 55 and give a construction of a (5, 6, 6, 5)-free M5 with w(S5) = 48.

Constructing and tabulating dihedral function fields

We present algorithms for constructing and tabulating degree-` dihedral extensions of Fq(x), where q ≡ 1 mod 2`. We begin with a Kummertheoretic algorithm for constructing these function fields with prescribed ramification and fixed quadratic resolvent field. This algorithm is based on the proof of our main theorem, which gives an exact count for such fields. We then use this construction metho...

The Artin conjecture for some S5-extensions

We establish some new cases of Artin’s conjecture. Our results apply to Galois representations over Q with image S5 satisfying certain local hypotheses, the most important of which is that complex conjugation is conjugate to (12)(34). In fact, we prove the stronger claim conjectured by Langlands that these representations are automorphic. For the irreducible representations of dimensions 4 and ...

A classification of the extensions of degree p 2 over Q p whose normal closure is a p - extension par Luca CAPUTO

Let k be a finite extension of Qp and Ek be the set of the extensions of degree p over k whose normal closure is a p-extension. For a fixed discriminant, we show how many extensions there are in EQp with such discriminant, and we give the discriminant and the Galois group (together with its filtration of the ramification groups) of their normal closure. We show how this method can be generalize...

The Totally Real A6 Extension of Degree 6 with Minimum Discriminant

Research Council (Canada) and Fonds pour la Formation de Chercheurs et l'Aide a la Recherche (Qu ebec). The totally real algebraic number field F of degree 6 with Galois group A 6 and minimum discriminant is determined. It is unique up to isomorphy, and is generated by a root of the polynomial t 6 ? 24t 4 + 21t 2 + 9t + 1 over the rationals. We also give an integral basis and list the fundament...
