This offers a 15% discount on all items. Additionally, for every order placed using the discount code GREEN15, they will plant two trees instead of the one they usually plant on most purchases.

Division rings in the service of group theory
Abstract
Embedding the group algebra into a division ring has proven to be a powerful tool for detecting structural properties of the group, especially in relation to its homology. In this talk, we will show how division rings can be used to identify residual properties of groups, one-ended groups, and coherent groups. We will place special emphasis on the class of free-by-cyclic groups to provide a clear, explicit exposition.
