Wednesday, April 21 Geometry and Topology Time: 11:30 Room: Zoom Meeting ID: 958 6908 4555 Speaker: Andres F. Fontalvo Orozco (ETH Zurich) Title: Traces and Link Invariants Ribbon categories can be used to produce invariants of framed links via the Reshetikhin-Turaev construction. We will examine this construction and use it to motivate a generalization of the categorical trace known as the module trace. We will then examine a few examples, and basic properties. We will finish discussing partial results regarding existence and uniqueness. |
