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…
