Schur -groups of type for
Eric Ahlqvist, Richard Pink
For any imaginary quadratic field , the Galois group of its maximal unramified pro--extension is a Schur -group. If this has Zassenhaus type , there are 13 p…
Weil representations associated to isocrystals over function fields
Maxim Mornev, Richard Pink
Every Anderson -motive over a field determines a compatible system of Galois representations on its Tate modules at almost all primes of . This adapts easily to -isocr…
Schur -groups of type (3,3)
Richard Pink
For any odd prime , the Galois group of the maximal unramified pro--extension of an imaginary quadratic field is a Schur -group. But Schur -groups can also be constru…
A Cohen-Lenstra Heuristic for Schur -Groups
Richard Pink, Luca Ãngel Rubio
For any odd prime and any imaginary quadratic field , the -tower group associated to is the Galois group over of the maximal unramified pro--extension of…
Reduction of Hyperelliptic Curves in Residue Characteristic 2
Tim Gehrunger, Richard Pink
Consider a hyperelliptic curve of genus over a field of characteristic zero. After extending we can view it as a marked curve with its Weierstrass points. We pre…
