This course covers the study of the main concepts and algorithms for the
analysis of complex networks, the models that summarize their most
relevant properties, and the dynamics which take place on top of them.
First, we show the presence of complex networks in all kinds of fields
(biology, medicine, ecology, social sciences, economy, linguistics, etc.) and the existence of several properties that are common to most of them. We will classify complex networks according to different criteria, and explain their main structural characteristics at three levels of description: microscale, macroscale and mesoscale. These include from descriptors at the level of nodes (e.g., degree, clustering coefficient and centrality measures) to global properties of the network (e.g., degree distributions, small-world property, transitivity and assortativity), and also showing the appearance of intermediate mesoscopic structures (e.g., community structure, rich-club and motifs). We will also study the main
models of complex networks, which allow the understanding of the
appearance of their distinctive structural properties. Finally, we will
describe some of the dynamics on complex networks, such as
diffusion, synchronization and epidemics spreading, and the analysis of the robustness of complex networks.
