Аннотация: The issues of preserving dynamic properties when passing from a system of differential equations to another system obtained by a change of variables, as well as the issues of preserving the properties in the opposite direction, are considered. The potential of the reduction method, which was proposed earlier, in resolving these questions are demonstrated by the examples of such properties as stability, attraction, and dissipativity. Similar issues are investigated for the case when the second system is obtained in a way characteristic for the comparison method with vector Lyapunov functions. The application of one of the obtained dissipativity criteria to analyzing the nonlinear dynamics of a group of moving objects is considered.
