摘要：
A condition for the existence of limit cycles in slow-fast dynamical systems is presented in this paper. The condition, used up to now to analyze relaxation oscillations in second-order systems, is extended to higher-dimensional systems and applied to models of particular interest. The analysis is purely geometric and based on singular perturbation arguments, and the limit cycles that the condition identifies are composed of alternate slow and fast transitions.
