| Title: | Seeking Exceptional Collections for Non-Exceptional Groups |
| Speaker: | Aaron Betram, University of Utah |
| Abstract: | |
| Castravet and Tevelev found a symmetric exceptional collection of line bundles and \r\ntorsion sheaves on the Losev-Manin space of pointed rational curves, which is naturally the compactificationof the maximal torus in PGL(n+1). With Alicia Lamarche, we have been working on a generalization to the other non-exceptional root systems, where we have found some surprises that I want to share with you. | |
