Noether's theorem and gauge transformations. Application to the bosonic string and CP(2,n-1) model [PDF]
, 1989 New results on the theory of constrained systems are applied to characterize the generators of Noethers symmetry transformations. As a byproduct, an algorithm to construct gauge transformations in Hamiltonian formalism is derived.

Electric–magnetic symmetry and Noether's theorem
New Journal of Physics, 2012 In the absence of charges, Maxwell's equations are highly symmetrical. In particular, they place the electric and magnetic fields on equal footing.

Noether’s theorem and the Willmore functional [PDF]
Advances in Calculus of Variations, 2015 Abstract Noether’s theorem and the invariances of the Willmore functional are used to derive conservation laws that are satisfied by the critical points of the Willmore energy subject to generic constraints. We recover in particular previous results independently obtained by R. Capovilla and J. Guven, and by T. Rivière.

Extensions of Noether's Second Theorem: from continuous to discrete systems [PDF]
, 2011 A simple local proof of Noether's Second Theorem is given. This proof immediately leads to a generalization of the theorem, yielding conservation laws and/or explicit relationships between the Euler--Lagrange equations of any variational problem whose ...

Energy in gravitation and Noether’s theorems* [PDF]
Journal of Physics A: Mathematical and Theoretical, 2019 I exhibit the conflicting roles of Noether’s two great theorems in defining conserved quantities, especially energy in general relativity and its extensions: it is the breaking of coordinate invariance through boundary conditions that removes the barrier her second theorem otherwise poses to the applicability of her first.
