Description
I will review recent progress in our understanding of symmetries of QFTs building on the idea that symmetries are encoded in a topological subsector of the operator spectrum. I will discuss some concrete examples of topological defects, as well as the way the latter account for quantum numbers of extended operators. Along the way we will touch upon some of the more recent applications, ranging from duality defects to the higher structure of chiral symmetry.
