This book presents a set of fractals, which were created as a visualization of the scientific results of the author on the nonlinear dynamics. This collection has been divided into three parts due to the three mathematical models. The first part refers to the complex hyperbole raised to the square. The second part refers to the complex variable has been raised to the complex variable. The third part based on mathematical models of the chemical reactor. Fractal images created by the author have not only aesthetic value. They also allow the evaluation of the sensitivity and stability of the model.
