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.
