Introduction to Complex and Econophysics Systems: a navigation map

We all experience complexity in everyday life, where simple answers are hard to find and the consequences of our actions are difficult to predict. Modern science recognizes that problems involving the collective behavior of many interacting elements are often “complex”. These systems typically display collective, organized behaviors that cannot be predicted from usual atomistic studies of their components in isolation. The resulting responses of complex systems are often counterintuitive. Their explanations require the use of new tools and new paradigms which range from network theory to multi-scale analysis. There is not a uniquely agreed definition of complex system, but if we
