Combinatorics Date:  Friday, October 12, 2012 Location:  3866 East Hall (4:10 PM to 5:00 PM) Title:  Subalgebras of the Fomin-Kirillov algebra Abstract:   The Fomin-Kirillov algebra is a quadratic algebra that was introduced to study the cohomology of the flag variety. We define for any graph a subalgebra of the Fomin-Kirillov algebra and investigate its properties. In particular, we conjecture that these subalgebras have a surprising number of nice properties analogous to those of finite Coxeter groups and their corresponding nil-Coxeter algebras. This is joint work with Jonah Blasiak and Karola Meszaros. Speaker:  Ricky Liu Institution:  UM Event Organizer:        Edit this event (login required). Add new event (login required).
