WebSep 25, 2015 · Let's state informally the general form of the Noether theorem: to every one-parameter group of diffeomorphism of the configuration manifold of a lagrangian system which preserves the lagrangian function, there correspond a first integral of the equations of motion. Let's state the general form of the Noether theorem (cfr. [1]). Theorem (Noether). Noether's theorem or Noether's first theorem states that every differentiable symmetry of the action of a physical system with conservative forces has a corresponding conservation law. The theorem was proven by mathematician Emmy Noether in 1915 and published in 1918. The action of a physical system is the integral over time of a Lagrangian function, from which the system's behavior can be determined by the principle of least action. This theorem only applies to continuous and …
