The theme of the seminar is to work through articles/arXiv preprints which represent important current developments,
at least initially in algebraic combinatorics. The seminar will meet (via zoom) on Tuesdays and Thursdays from
12-1pm Philadelphia time (unless otherwise noted in the schedule below). Each seminar session will have a "host" who will be responsible for presenting
material, but the degree to which the seminar will be a series of lectures or more of a group discussion
may vary from week to week. If you wish to attend the talks email me or Anna to get the zoom link
(jhaglund "at symbol" math.upenn.edu, annapunying "at symbol" gmail.com).
Recordings of the talks will be made if the host is agreeable.
The first paper we will be working through this summer is "Towards Butler's Conjecture" by Donghyun Kim, Seung Jin Lee, and Jaeseong Oh,
available on the arXiv. The seminar will run from early June
to late August.
See the table below for our schedule for the 2023 Summer Season. (Note the first series of talks occur at 9pm Philadelphia time).
