DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SymSem/19/">
 A classification of 3+1D topological orders and non-degenerate unitary bra
 ided fusion 2-category</a>\nby Xiao-Gang Wen (MIT) as part of Symmetry Sem
 inar\n\n\nAbstract\nI will discuss the microscopic definition of topologic
 al orders in 3d space and its connection with non-degenerate unitary braid
 ed fusion 2-categories (or unitary fusion 3-categories with trivial center
 ). Then I will discuss a "physical" classification of  3+1D topological or
 ders (and non-degenerate unitary braided fusion 2-categories or unitary fu
 sion 3-categories with trivial center).\n
