Noether's theorem is “one-dimensional” in the sense that for each symmetry (a vector field of a special kind on the phase space), it provides a conserved quantity, i.e. a real-valued function on the phase space, whose value stays constant over time. From: Philosophy of Physics, 2007

Noether’s Theorem September 15, 2014 There are important general properties of Euler-Lagrange systems based on the symmetry of the La-grangian.

Till exempel: translationsinvarians i rummet svarar mot rörelsemängdens bevarande,; translationsinvarians i tiden svarar mot energins bevarande,; rotationssymmetri svarar mot rörelsemängdsmomentets bevarande.

What is generally known as Noether's Theorem states that if the Lagrangian function for a physical system is not affected by a continuous change (transformation) in the coordinate system used to describe it, then there will be a corresponding conservation law; i.e. there is a quantity that is constant. Das Noether-Theorem (formuliert 1918 von Emmy Noether) verknüpft elementare physikalische Größen wie Ladung, Energie und Impuls mit geometrischen Eigenschaften, nämlich der Invarianz (Unveränderlichkeit) der Wirkung unter Symmetrietransformationen: .

Noether’s theorem is based upon a mathematical proof. It’s not a theory. Her proof can be applied to physics to develop theories, however. Now that we know what the principle of least action is, we

Noethers teorem

2005-06-22 · Noether's theorem is a central result in theoretical physics that expresses the one-to-one correspondence between the symmetries and the conservation laws.This exact equivalence holds for all physical laws based upon the action principle defined over a symplectic space.

The theorem was proven by mathematician Emmy Noether in 1915 and published in 1918, after a special case was proven by E. Cosserat and F. Cosserat in 1909.
