| 3 | Classification of Variational Conservation Laws of General Plane Symmetric Spacetimes显示文摘In this article we discuss Noether conservation laws admitted by a Lagrangian L = gab(dx^a/ds)(dx^b/ds)of a test particle moving in the field of a general plane symmetric non-static spacetime metric. In this context, we first present a general solution representing a Noether symmetry vector subject to differential constraints satisfied by the general plane symmetric non-static metric. We then use a class of plane symmetric non-static metrics obtained by Feroze et al. and discuss, in each case, Noether conservation laws in comparison with Killing symmetries. | Usamah S.Al-Ali Ashfaque H.Bokhari A.H.Kara Ghulam Shabbir | 2017 | Communications in Theoretical Physics2017，67，9： | 0 |
