Title: Classification of SET orders with onsite symmetries
Abstract: In this talk I will explain two different approaches towards the classifications of symmetry protected trivial (SPT) orders and symmetry enriched topological (SET) orders with unitary finite onsite symmetries in all dimensions. The first approach is based on the idea of gauging the symmetry. I will explain this idea for 2d SPT/SET orders in details. The second approach is based on the boundary-bulk relation. All the information of a SET order is contained in the bulk.
