Title: Integral hyperplane arrangements
Time: 2:30 PM, Monday, September 12, 2016
Place: Malott 206
Abstract: Consider an arrangement of linear hyperplanes integral with
respect to a given lattice. The lattice gives rise to a torus and the
arrangement to a subdivision of the torus. We are interested in the
combinatorics of this subdivision. We will describe questions and
results for particular lattices associated to root systems and
arrangements associated to graphs. This is joint work with Swee Hong Chan (Cornell).
