Spring 2022


The Columbia Algebraic Geometry Seminar takes place on Fridays at 3:30 pm in 417 Mathematics Hall on the Columbia campus. Some talks will be streamed on Zoom (password is the number of lines on a cubic surface).

The seminar is organized by Giulia Saccà, Will Sawin, and Akash Sengupta.
