This book investigates uncontrolled and controlled time-continuous and time-discrete systems. It examines the question of controllability of dynamical systems into equilibrium states as well as chaotic behavior of autonomous time discrete systems.

At the end of the nineteenth century Lyapunov and Poincaré developed the so called qualitative theory of differential equations and introduced geometric- topological considerations which have led to the concept of dynamical systems. In its present abstract form this concept goes back to G.D. Birkhoff. This is also the starting point of Chapter 1 of this book in which uncontrolled and controlled time-continuous and time-discrete systems are investigated. Controlled dynamical systems could be considered as dynamical systems in the strong sense, if the controls were incorporated into the state space. We, however, adapt the conventional treatment of controlled systems as in control theory. We are mainly interested in the question of controllability of dynamical systems into equilibrium states. In the non-autonomous time-discrete case we also consider the problem of stabilization. We conclude with chaotic behavior of autonomous time discrete systems and actual real-world applications.

From the reviews:

"This monograph deals with diverse areas of the theory of dynamical systems, such as stability, controllability and chaotic behavior. The authors´ presentation is precisely limited to these topics, and is self-contained and illustrated by a number of useful examples. The text is easy to read. ... This book can be recommended for everybody interested in the mathematical formulation of controllability and chaotic behavior in general." (Denis Efimov, Mathematical Reviews, Issue 2012 a)

"This book brings together three strands of mathematical thinking, two of them conventionally labelled as ´dynamical systems´. ... Used in conjunction with a standard text in dynamical systems or control theory, this would be an interesting supplement to a course in either discipline." (Thomas B. Ward, Zentralblatt MATH, Vol. 1207, 2011)
