Explore the concept of outer spaces in virtually free groups through this 51-minute lecture by Rylee Lyman. Delve into the definition of virtually free groups and their characterization through the Karrass, Pietrowski, and Solitar theorem. Learn about the deformation space of trees with finite stabilizers and finite quotients, known as Outer Space. Examine the relationship between this Outer Space and that of the free subgroup of finite index. Gain insights into advanced topics in geometric group theory as part of the Workshop on Geometry of Subgroups hosted by the Centre de recherches mathématiques (CRM).
