The aim of this book is to develop concepts and methods that allow us to deal with economic systems from a unifying physically motivated point of view. An economy is usually classified as a manifestation of complex social systems. To clarify this statement, we have to discuss what we mean by complex systems. Unfortunately, an exact definition of complex systems is still an open problem. In a heuristic manner, we may describe them as:
