The Noether symmetry and the conserved quantity for a fractional actionlike variational problem in phase space are studied based on the method of fractional dynamics modeling presented by El-Nabulsi
namely fractional actionlike variational approach. First
the fractional actionlike variational problem in phase space is established
and the fractional actionlike Hamilton canonical equations are obtained. Secondly
the definitions and criteria of the fractional actionlike Noether (quasi)symmetrical transformations are presented in terms of the invariance of the fractional actionlike integral of Hamilton under the infinitesimal transformation of group. Finally
the Noether theorems for the fractional actionlike Hamiltonian system are given
the relationship between the Noether symmetry and the conserved quantity of the system is established.An example is given to illustrate the application of the results.
