Abstract:
This paper discusses the conformal invariance by infinitesimaltransformations of canonical Hamilton systems. The necessary andsufficient conditions of conformal invariance being Lie symmetricalsimultaneously by the action of infinitesimal transformations aregiven. The determining equations of the conformal invariance aregained. Then the Hojman conserved quantities of conformal invarianceby special infinitesimal transformations are obtained. Finally anillustrative example is given to verify the results.
