Conservation Laws and Symmetries
Physical Review, 1966The possibility of an arbitrary conserved current, with any tensorial rank and having explicit dependence on space-time variables, being associated with an invariance property is investigated. It is proved, in the Lagrangian formalism of local quantum field theory, that conserved currents satisfying certain reasonable requirements must have the ...

Abstract This chapter deals with various conservation laws for a moving fluid: conservation of mass, of momentum, and of energy. The question of the conservation of mass, already derived in Chapter 3, is only briefly restated here (Section 5.1), while the conservation of circulation (angular momentum) is treated in detail in Chapter 7.

Abstract This chapter studies how the ‘spacetime symmetries’ can generate first integrals of the equations of motion which simplify their solution and also make it possible to define conserved quantities, or ‘charges’, characterizing the system.
