Has anything been written on the following: Noether's 1stNoether's first variational theorem establishes a correspondence betwweenbetween symmetries and invariants. If we deformI would like to know what has been written on the symmetries,following question: How do the invariants deform as... Howwhen we deform the symmetries? How about if the Lie algebra of symmssymmetries is deformed as an L-inftyinfinity-algebra?
