DESCRIPTION:We discuss the interplay between extended operators (i.e. defe
 cts) and symmetries\, anomalies\, and renormalization group flows in quant
 um field theory.&nbsp\;\nWe also give some examples in lattice models.&nbs
 p\;&nbsp\;\nWe emphasize defects in gapless systems\, namely defects in co
 nformal field theories.\nReferences\nThis review of symmetries in quantum 
 mechanics&nbsp\;https://kantohm11.github.io/symmetry_review/&nbsp\;\nAnd t
