Title: A 2-Categorical Perspective on Braided Fusion 1-Categories

Abstract: I will review the definition of a fusion 2-category. In particular, I will explain how one can associate a fusion 2-category to any braided fusion 1-category. Then, I will introduce the concept of Morita equivalence between fusion 2-categories, and examine some examples. Specifically,  I will explain how the notion of Morita equivalence between fusion 2-categories recovers the notion of Witt equivalence between arbitrary braided fusion 1-categories introduced by Davydov, Nikshych, and Ostrik.
