Dear all, This is a gentle reminder of the CART seminar by Hunter Spink (University of Toronto) on 10:30 - 11:30 am tomorrow (in Korea time). Hope to see you at the seminar! Best regards, Sin-Myung Lee -----------------------원본 메세지----------------------- 보낸사람: "이신명"<sinmyunglee(a)kias.re.kr> 받는사람: "이신명" <sinmyunglee(a)kias.re.kr> 보낸날짜: 2025-09-03 21:47:12 GMT +0900 (Asia/Seoul)제목: CART Seminar announcement (Hunter Spink, Sep 11 (Thu), 10:30AM) Dear all, The CART seminar is coming back, with the first talk scheduled for Sep 11th (Thu), 10:30 - 11:30 (Korea time). [Note: this fall we plan to organize most of our seminars on Thursdays!] We will welcome Hunter Spink from University of Toronto, who will tell us about: Title: The Coxeter flag variety: A toric complex on noncrossing partitions paved by clusters Abstract: (Joint with Nantel Bergeron, Lucas Gagnon, and Vasu Tewari) In this talk I will introduce a new toric complex we call the "Coxeter flag variety" in G/B, defined as the vanishing of Plucker coordinates away from the subset of the Weyl group called the "c-noncrossing partitions" for c a standard Coxeter element. The combinatorics of this variety encodes the geometry of certain Richardson varieties R_{w,wc}, each of which has a distinguished affine chart whose characters correspond to positive clusters. You can join the seminar via the following Zoom link: https://us06web.zoom.us/j/82283035487?pwd=r25KFTmr0hhVNKjvqUjHPvyTL6mVaN.1 ID: 822 8303 5487 password: 395575 Please feel free to forward this to anyone who might be interested.
