Algebra Seminar: Nguyen -- Type A-admissible cells are Kazhdan-Lusztig

Van Minh Nguyen (University of Sydney) 

Friday 12 October, 12-1pm, Place: Carslaw 375 

Title: Type A-admissible cells are Kazhdan-Lusztig 

Abstract: This talk is based on recent preprint: Type A-admissible cells are
Kazhdan-Lusztig.  Specifically, I will show that in type A, admissible cells are
isomorphic to Kazhdan-Lusztig left cells, as conjectured by Stembridge in Admissible
W-graphs (Representation Theory 12 (2008)).  I will also explain how some details of the
proof provide us with an effective algorithm to compute W-graphs for left cells.
