The 2-linearity of the free group and the topology of the punctured disc

Presented by: 
Anthony Licata Australian National University
Thursday 27th April 2017 - 15:15 to 16:15
INI Seminar Room 2
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.
