Abstract:
In this paper, a new type of conserved quantity directly
deduced from the Mei symmetry for relativistic variable mass system in
phase space is studied. The definition and the criterion of the Mei
symmetry for the system are given. The conditions for existence and the
form of the new conserved quantity are obtained. Finally, an example is
given to illustrate the application of the results.
