NAAPing Class Group

# Working group on Number theory, Arithmetic & Algebraic geometry, & Physics

• The aim of this working group is to meet regularly in order to work on problems on the interface of number theory, arithmetic geometry, algebraic geometry and physics. In addition to working group sessions, we will also have regular seminars/talks/lectures by members of the working group as well as external speakers.

• Seminars take place over Zoom; Working groups meet on Gather Town or Zoom breakout rooms.

• To sign up for this working group or to join the seminars mailing list, please fill out this form or please reach out to the email listed in Contact section below.

• If you would like to give a seminar within this working group or suggest a speaker, please email Abhiram (see Contact section below).
