Description
In this lecture, I will give a brief introduction to geometric group theory. After reviewing the basic terminology and concepts of groups, graphs and trees, I will explain the construction of Cayley graphs. I will then focus on the case of free groups. I describe how Cayley graphs work when you prove group theoretic results on free groups such as Nielsen-Schreier Theorem.
