A classification of 3+1D topological orders and non-degenerate unitary braided fusion 2-category

Abstract: I will discuss the microscopic definition of topological orders in 3d space and its connection with non-degenerate unitary braided fusion 2-categories (or unitary fusion 3-categories with trivial center). Then I will discuss a "physical" classification of 3+1D topological orders (and non-degenerate unitary braided fusion 2-categories or unitary fusion 3-categories with trivial center).
