Noether's theorem in nLab
Noether's first theorem is a theorem due to Emmy Noether (Noether 1918) which makes precise and asserts that to every continuous symmetry of the Lagrangian ...
Emmy Noether (1882–1935) was a German mathematician with important results in theoretical physics (see Noether's theorem) and abstract algebra.
