Summary:The paper studies relationships (inclusions, coincidences, and noncoincidences) between classes of linear approximations that provide various properties of Lyapunov, Perron, and upper-limit stability or instability (from global to particular) of the zero solution to a differential system of arbitrary order. A complete set of noncoinciding stability classes is presented and some considerations are given for a similar description of instability classes.
