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.
