The CAGE (Combinatorics, Algebra, and Geometry) Seminar
The 2024-2025 CAGE seminar is co-organized by
Jonah Blasiak of Drexel University,
Linda Chen of Swarthmore College,
Jim Haglund of Penn,
Alexander Diaz-Lopez of Villanova University,
Darij Grinberg of Drexel University,
Liz Milićević of Haverford College, and
Mark Skandera of Lehigh University.
Our seminar is back. We meet on Thursdays from 3:30-4:30 pm at either
UPenn (usually, but not always, in DRL 2C4 -- note the new room!) or Drexel (Korman 245).
Up-to-date information regarding the location and organization of the seminar will be sent out
through the CAGE seminar mailing list the morning of the seminar. To be
added to the list, email us at jhaglund "at" math.upenn.edu or darij.grinberg "at" drexel.edu.
See the table below for our schedule for the 2024-2025 Academic year.
