On the radii of Voronoi cells of rings of integers

Frauke M. Bleher, Ted Chinburg, Xuxi Ding +2

Since the time of Minkowski a basic problem in number theory has been to find lower bounds for the absolute value $I^ (K)$ of the discriminant of a number field $K$ in terms of the…

Explicit Approximations to Class Field Towers

Frauke M. Bleher, Ted Chinburg

We answer a question of Peikert and Rosen by giving for each $I^µ > 0$ an efficient construction of infinite families of number fields $N$ such that the root discriminant $D_N^{1/[N:…

Holomorphic differentials of alternating four covers

Frauke M. Bleher, Margarita Bustos Gonzalez

Suppose $k$ is an algebraically closed field of characteristic two, let $A_{4}$ be an alternating group on four letters, and let $H$ be the unique Sylow two-subgroup of $A_{4}$ . Let $X…

Triple Massey products for higher genus curves

Frauke M. Bleher, Ted Chinburg, Jean Gillibert

We study the vanishing of triple Massey products for absolutely irreducible smooth projective curves over a number field. For each genus $g > 1$ and each prime $ℓ > 3$ , we const…
