We explore various generalizations of the notion of symmetry and Noether’s theorem. We show how some new results about phases of gauge theories can be derived from thinking about symmetries more carefully and abstractly. We provide some examples in 2,3, and 4 dimensions.
We also make some comments on the notion of naturalness and show how in some two-dimensional theories it is violated.
