This year's course will cover the theory of expanders. Expanders are very well connected graphs with only few edges, which can be used as cheap substitutes for complete graphs. The first construction of infinite families of expanders of bounded degree is rather recent, and they have applications in very diverse fields like complexity theory, error correcting codes, pseudo-randomness, embedding of finite metric spaces. After reviewing some constructions of expanders, we will discuss such applications, which should illustrate the richness of Mathematics motivated by problems in Theoretical Computer Science.
