Abstract
Symmetry is really determined by the algebra of local symmetric operators. Such an operator algebra is described by a braided fusion higher category. So a symmetry is really a topological order in one higher dimension. This point of view reveals that many seemingly different (anomalous) symmetries are actually equivalent.
