Complex networks are everywhere in the world around us: communication networks, transportation networks, networks of friends and acquaintances, and biological networks, to name a few. In this course, students will learn the similarities and mathematical abstractions that lie beneath these examples. Other examples drawn from molecular biology (gene regulation and protein interaction networks), economics (trade networks, relationships between companies and the strategic interactions on networks), computer networks (Internet, world wide web), and ecology (food webs). In the last decade there has been an explosion of work in the theory and applications of networks to a vast range of problems. Students who complete this course will receive a broad introduction to recent work in this area, understand the strengths and weaknesses of modeling the network, and may apply networks and their analysis in a variety of configurations.
In the first part of the course we focus on the empirical description of the network structure. Then, we turn our attention to the dynamics of networks: how networks are formed and grow, and how these rules of growth are related to the overall structure. Finally, we consider algorithms and dynamics on top of networks. In the latter part of the course we will present issues related to the spread of diseases and viruses in the network, how to detect the community structure in networks, and for example, how it works the Google PageRank algorithm.
