This text concentrates on constructing an exposition of the method of normal forms, a mathematical tool which allows one to simplify as much as possible a complex dynamic system and then study the system and its application to ordinary differential equations through perturbation analysis. Many examples are provided as is an introduction to symbolic computing.
