| Abstract: | The conformal invariance of the differencial equations for nonholonomic mechanical systems with variable mass by infinitesimal transformations is studied.The concept of the conformal invariance of the systems is proposed.It is derived that the clifferential equations have the conformal invariance.It is proved that the conditions of the conformal invariance are the necessary and sufficient conditions for Lie symmetry.. |
