Connections Between Symmetries and Conservation Laws

Symmetry, Integrability and Geometry: Methods and Applications, 2005
This paper presents recent work on connections between symmetries and conservation laws. After reviewing Noether's theorem and its limitations, we present the Direct Construction Method to show how to find directly the conservation laws for any given ...

A geometric derivation of Noether’s theorem

European Journal of Physics
Abstract Nother’s theorem is a cornerstone of analytical mechanics, making the link between symmetries and conserved quantities. In this article, I propose a simple, geometric derivation of this theorem that circumvents the usual difficulties that a student of this field usually encounters.

Noether's Theorem for a Fixed Region

, 2009
We give an elementary proof of Noether's first Theorem while stressing the magical fact that the global quasi-symmetry only needs to hold for one fixed integration region. We provide sufficient conditions for gauging a global quasi-symmetry.

Variational problems of Herglotz type with time delay: DuBois-Reymond condition and Noether's first theorem

We extend the DuBois-Reymond necessary optimality condition and Noether's first theorem to variational problems of Herglotz type with time delay. Our results provide, as corollaries, the DuBois-Reymond necessary optimality condition and the first Noether
