Algebraic Geometry and Combinatorics Seminar: The geometry of algebras associated to hyperplane arrangements
Speaker: Matt Larson, Princeton University
Abstract: The space of sections of a line bundle on an equivariant compactification of a commutative algebraic group naturally has a coalgebra structure. We show that a well-studied family of algebras associated to hyperplane arrangements can be realized in this way. This allows us to apply powerful tools from sheaf cohomology to some combinatorial algebra problems. Joint work with Colin Crowle.
