Abstract: Renormalization group method arises from the study of many-body interaction in statistical physics and quantum field theory, which is capable of reducing complex dynamics to effective ones. In recent years, it has been applied in the analysis of nonlinear dynamics and achieved remarkable success. Here, I gave a few examples of dynamical systems to illustrate its application, ranging from simple nonlinear dynamics on a plane to high-dimensional complex behavior.
