Preliminary Arizona Winter School 2025: Mathematical cryptography and algorithms in number theory
The Preliminary Arizona Winter School (PAWS) is a virtual program on topics related to the upcoming AWS, with an intended audience of advanced undergraduate students and junior graduate students.
Registration is now closed; the deadline to apply was July 26th, 2025. Videos, notes, and problem sets will be available at this page for anyone who missed the registration deadline.
September 22nd — November 21st, 2025
PAWS 2025 consists of two concurrent lecture series.
Format: The program will run for 9 weeks, alternating between 5 weeks of lectures and 4 weeks of problem sets (with a TA session)
Each lecturer will be accompanied by graduate student assistants, who will be in charge of writing weekly problem sets and facilitating weekly, hour-long problem solving and discussion meetings with groups of students.
Introduction to mathematical cryptography will assume only a first undergraduate course in abstract algebra as a prerequisite. Analysis and implementation of algorithms in number theory will assume fluency with algebra at a beginning graduate level and familiarity with the basic objects of algebraic number theory (such as number fields and their rings of integers), but will not assume any prior experience with analysis of algorithms.
Organizers: Renee Bell, Brandon Levin and Padmavathi Srinivasan (main organizers)
with Anthony Várilly-Alvarado, Isabel Vogt and Hang Xue.
