Title: Quivers and Plabic Graphs

Abstract: Quivers are the main combinatorial objects that correspond to cluster algebras. For the uninitiated, we will give a brief introduction to the kinds of quivers that appear, and the rules for mutating them. Then we will introduce plabic graphs, another tool for working with cluster structures. We will discuss moves on plabic graphs and describe how to recover quivers from them.
