Discussion and Future Directions

Abstract

As we saw throughout this book, despite the many studies in graph theory and combinatorics, neurophysiology, botanic, geography, and transport studies among others, we do not have a full understanding of the structure and evolution of spatial networks. In addition, these networks are not just simple structures embedded in a substrate but constitute the support for dynamical processes: it can be the traffic on transport networks, electric flow on power grids, or the spread of nerve impulses in neural networks.
