Chapter 1 recalls Tikhonov's theory for slow-fast systems in case of steady state fast dynamics. Chapter 2 deals with Pontryagin-Rodygin's theorem where the fast dynamics are periodic. We propose a new proof of this theorem emphasizing on its topological features. These results concern bounded time intervals. We indicate in Chapter 3 how the geometrical theory of perturbations treats the case of the oscillating fast dynamics. In Chapter 4, results for unbounded time intervals are established when the fast dynamics converge to a positively invariant compact subset. These results lead to practical stability theorems. Chapter 5 is devoted to the case where the fast equation has cycles with relaxation. A rigorous result describes the slow motio...
