Rachel Skipper (Ohio State): The Cantor-Bendixson rank of the Grigorchuk group

The space of subgroups of a group has a natural Polish topology and understanding this space can help to understand the group.
In this talk, we will consider the Cantor-Bendixson derivative and rank for the space of subgroups of the Grigorchuk group, using it to stratify the subgroups of this group.
