Schur $σ$ -groups of type $(3, 3)$ for $p = 3$

Eric Ahlqvist, Richard Pink

For any imaginary quadratic field $K$ , the Galois group $G_{K}$ of its maximal unramified pro- $3$ -extension is a Schur $σ$ -group. If this has Zassenhaus type $(3, 3)$ , there are 13 po…

Weil representations associated to isocrystals over function fields

Maxim Mornev, Richard Pink

Every Anderson $A$ -motive $M$ over a field determines a compatible system of Galois representations on its Tate modules at almost all primes of $A$ . This adapts easily to $F$ -isocr…

Schur $σ$ -groups of type (3,3)

Richard Pink

For any odd prime $p$ , the Galois group of the maximal unramified pro- $p$ -extension of an imaginary quadratic field is a Schur $σ$ -group. But Schur $σ$ -groups can also be construct…

A Cohen-Lenstra Heuristic for Schur $σ$ -Groups

Richard Pink, Luca Ángel Rubio

For any odd prime $p$ and any imaginary quadratic field $K$ , the $p$ -tower group $G_{K}$ associated to $K$ is the Galois group over $K$ of the maximal unramified pro- $p$ -extension of…

Reduction of Hyperelliptic Curves in Residue Characteristic 2

Tim Gehrunger, Richard Pink

Consider a hyperelliptic curve of genus $g$ over a field $K$ of characteristic zero. After extending $K$ we can view it as a marked curve with its $2 g + 2$ Weierstrass points. We pre…

Local Kummer theory for Drinfeld modules

Maxim Mornev, Richard Pink

Let $ϕ$ be a Drinfeld $A$ -module of finite residual characteristic $p ˉ$ over a local field $K$ . We study the action of the inertia group of $K$ on a modified adelic…

Reduction of Hyperelliptic Curves in Characteristic $\neq = 2$

Tim Gehrunger, Richard Pink

Let $K$ be the quotient field of a discrete valuation ring $R$ with residue characteristic $\neq = 2$ , and let $C$ be a hyperelliptic curve over $K$ . We assume that all geometric bra…
