چکیده
|
Noether symmetries provide conservation laws that are admitted by lagrangians representing physical systems. for partial differential equation possessing lagrangians these symmetries are obtained by the invariance of the corresponding action integral. in this paper we provide a systematic procedure for determining noether symmetries and conserved vectors for a lagrangian constructed from a lorentzian metric of interest in mathematical physics. for completeness,we give lie point symmetries and conservation laws admitted by the wave equation on this lorentzian metric. © 2012 ahmad m. ahmad et al.
