Abstract. In this Letter we have studied the behavior of the Fast-Lyapunov Indicators for various attractors of the Gumowski-Mira map. It was observed that the Fast-Lyapunov indicators show a typical type of behavior for different kinds of attractors, viz. chaotic, periodic, and bounded attractors. We have shown the possibility of a transient chaos in GM-map. The importance of FLI in dynamical system or maps is suggested.
