On the inversion of Noether's theorem in the Lagrangian formalism: II.—Classical field theory
(1970-01-01)
Both the «direct» and the «inverse» Noether's theorems are generalized to allow for infinitesimal transformations that add to the action functional an integral over a 4-divergence and an integral over a function vanishing ...

As Simetrias de Lie de um Pião
(Sociedade Brasileira de Física, 2018)
The existence of symmetries in differential equations can generate transformations of dependent and independent variables that facilitate the integration of these equations. In the nineteenth century, Sophus Lie developed ...
The Noether theorem for geometric actions and area preserving diffeomorphisms on the torus
(1990-12-01)
We find that within the formalism of coadjoint orbits of the infinite dimensional Lie group the Noether procedure leads, for a special class of transformations, to the constant of motion given by the fundamental group ...
