• Proof:Noeter theorem
  ...he transform is identical, id est, \(y\!=\!x\) and \(v\!=\!u\); and in the linear approximation with respect to \(\varepsilon\), Some transforms of coordinates and fields keep the action invariant. These transforms correspond to the symmetry of the model. Each of continuous symmetries of t
