Dynamic Networks University of Bordeaux
Course Overview
Our every day life is shaped by social and economic networks: theinformation we have, how we learn and form opinions, the diseases thathurt us, our job decisions, the prices we charge or pay and even howwe make friends and enjoy life. In this course we provide advancedmaterials on some of the main themes in the theory of networks thatwill help us understand and deal will all thosequestions, and more. Studying networks is fun and open minded as itlies at the cross roads of different fields of science. We present anddiscuss in class theoretical models from economics, sociology, maths,physics, statistics and computer science. Last but not least, we dealwith the empirics of networks and learn how to make regressions andtest hypotheses on such data, something that becomes increasinglyimportant in the social networks / internet industry.

Course prerequisites
This course builds on IREF M1 class UE 2.1.6 "Analyse des réseaux". Ithus assume you are familiar to the following notions: basic graphnotations, Poisson random networks, preferential attachment in growingnetworks, Milgram experiment, clustering coefficient, small worlds àla Watts & Strogatz, network centrality notions (including Bonacich,Katz and Page Rank), degree distribu-tion.

Grading Philosophy
Students may match in pairs to realize a mini research project withwill bring three grades: Data treatments (40%), Reasoning (40%),Presentation (20%). A specific dataset will be provided to each groupwith a mission" to be fulfiled.
