Abstract: | The goal of this talk will be to describe a rather basic linear action of the free group on a finitely-generated triangulated category, and describe two proofs of the faithfulness of this action. I will also describe some of the geometric group theory and topology that is visible from the lens of this faithful 2-representation.
