Connections Between Symmetries and Conservation Laws [PDF]

open access: yesSymmetry, 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 ...

The conservation laws of several 2+1 dimensional semi-discrete equations

open access: yesPartial Differential Equations in Applied Mathematics, 2022
In this paper, we further develop and enrich the results on conservation laws obtained in Zhu (2003) and present two forms of conservation laws in different directions.

Conservation laws in quantum noninvasive measurements

open access: yesPhysical Review Research, 2021
Conservation principles are essential to describe and quantify dynamical processes in all areas of physics. Classically, a conservation law holds because the description of reality can be considered independent of an observation (measurement). In quantum

New asymptotic conservation laws for electromagnetism

open access: yesJournal of High Energy Physics, 2021
We obtain the subleading tail to the memory term in the late time electromagnetic radiative field generated due to a generic scattering of charged bodies. We show that there exists a new asymptotic conservation law which is related to the subleading tail

Characteristics of Conservation Laws for Difference Equations [PDF]

open access: yes, 2013
Each conservation law of a given partial differential equation is determined (up to equivalence) by a function known as the characteristic. This function is used to find conservation laws, to prove equivalence between conservation laws, and to prove the ...

SYMMETRY AND CONSERVATION LAWS [PDF]

open access: yesProceedings of the National Academy of Sciences, 1964
Symmetry and invariance considerations, and even conservation laws, played undoubtedly an important role in the thinking of the early physicists, such as Galileo and Newton, and probably even before then. However, these considerations were not thought to be particularly important and were articulated only rarely.
