Noether symmetry and the Hojman conserved quantity of the Kepler equation
Kepler方程的Noether对称性与Hojman守恒量

The Noether symmetry and the Hojman conserved quantities of the Kepler equation are studied. The determining equations of Noether symmetry for the system are given. A theorem asserting that the Noether symmetry for the system leads to the Hojman conserved quantity is presented.
