| Abstract: | In this paper, a general approach to the construction of conservation laws for Vacco dynamical systems were presented. Firstly, the definition of integrating factors was given. Secondly, necessary conditions for existence of the conserved quantities were studied in detail. Then the conservation theorem and its inverse theorem for the variable mass nonholonomic Vacco dynamical systems were established. Finally, an example was given to illustrate the application of the results. |
