Women in Numbers 2: Research Directions in Number Theory

A co-publication of the AMS and Centre de Recherches Mathématiques
The second Women in Numbers workshop (WIN2) was held November 6–11,
2011, at the Banff International Research Station (BIRS) in Banff,
Alberta, Canada. During the workshop, group leaders presented open
problems in various areas of number theory, and working groups tackled
those problems in collaborations begun at the workshop and continuing
long after.
This volume collects articles written by participants of WIN2.
Survey papers written by project leaders are designed to introduce
areas of active research in number theory to advanced graduate
students and recent PhDs. Original research articles by the project
groups detail their work on the open problems tackled during and after
WIN2. Other articles in this volume contain new research on related
topics by women number theorists.
The articles collected here encompass a wide range of topics in
number theory including Galois representations, the Tamagawa number
conjecture, arithmetic intersection formulas, Mahler measures, Newton
polygons, the Dwork family, elliptic curves, cryptography, and
supercongruences.
WIN2 and this Proceedings volume are part of the Women in Numbers
network, aimed at increasing the visibility of women researchers'
contributions to number theory and at increasing the participation of
women mathematicians in number theory and related fields.
