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 $Δ (K)$ of the discriminant of a number field $K$ in terms of the d…

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…

Explicit Approximations to Class Field Towers

Frauke M. Bleher, Ted Chinburg

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

Holomorphic differentials of Klein four covers

Frauke M. Bleher, Nicholas Camacho

Let $k$ be an algebraically closed field of characteristic two, and let $G$ be isomorphic to $Z /2 \times Z /2$ . Suppose $X$ is a smooth projective irreducible curve…

The Galois module structure of holomorphic poly-differentials and Riemann-Roch spaces

Frauke M. Bleher, Adam Wood

Suppose $X$ is a smooth projective geometrically irreducible curve over a perfect field $k$ of positive characteristic $p$ . Let $G$ be a finite group acting faithfully on $X$ over…
