Geometric Group Theory Seminar - Jingyin Huang
Title: Uniform lattices acting on RAAG complexes
Speaker: Jingyin Huang (McGill University)
Abstract: It is a classical result by Bieberbach that uniform lattices acting on Euclidean spaces are virtually free abelian. On the other hand, uniform lattices acting on trees are virtually free. This motivates the study of commensurability classification of uniform lattices acting on RAAG complexes, which are cube complexes that "interpolate" between Euclidean spaces and trees. We show the tree times tree obstruction is the only obstruction for commmensurability of label-preserving lattices acting on RAAG complexes.
