In this paper we extend the results on the multiple time-scale structure for linear autonomous systems of the form $$\dot x = A( \in )x$$ (cf. Coderchet al. [1]) to nonlinear autonomous systems. Our main result is in obtaining conditions under which the linearized system and the nonlinear system around an equilibrium point have the same time-scale structure.

All eigenvalues ofA 0 (ε) are in the open left half plane except possibly some at the origin. Further, there are no generalized eigenvectors associated with the zero eigenvalue.
