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.
