This textbook introduces the language and the techniques of the theory of dynamical systems of finite dimension for an audience of physicists, engineers, and mathematicians at the beginning of graduation. Author addresses geometric, measure, and computational aspects of the theory of dynamical systems. Some freedom is used in the more formal aspects, using only proofs when there is an algorithmic advantage or because a result is simple and powerful.
The first part is an introductory course on dynamical systems theory. It can be taught at the master's level during one semester, not requiring specialized mathematical training. In the second part, the author describes some applications of the theory of dynamical systems. Topics often appear in modern dynamical systems and complexity theories, such as singular perturbation theory, delayed equations, cellular automata, fractal sets, maps of the complex plane, and stochastic iterations of function systems are briefly explored for advanced students. The author also explores applications in mechanics, electromagnetism, celestial mechanics, nonlinear control theory, and macroeconomy. A set of problems consolidating the knowledge of the different subjects, including more elaborated exercises, are provided for all chapters.

Über den Autor / die Autorin
Rui Dilão is Professor of Mathematical Physics and Dynamical Systems at Instituto Superior Técnico of the Technical University of Lisbon. In 1986, he obtained the Ph.D. in Physics (Mathematical Physics) from the Technical University of Lisbon and, in 1997, the Habilitation from the same university. In the period 1986-1988 he has been Fellow at CERN, where he collaborated in the planning of the Large Hadron Collider. He has been Collaborator of the scientific program associated with the Portuguese satellite PoSAT-1 (1992-93). In 1999, together with two colleagues, he received the LabMed prize for original research work on laboratorial research medicine. He has also experience on general computational techniques and on mathematical techniques in finance and economics. He has also experience in general computational techniques, biophysics and economics.
