The Laplacian on metrized graphs
The aim of this course is to study the Laplacian operator, which is a fundamental tool in potential theory, on metrized graphs. After constructing it, we will see some of its basic properties. Next, we will explain how acts the Laplacian on some spaces (like the space of continuous, piecewise affine real-valued functions on a metrized graph, the Zhang space etc) and we will also prove some strong statements, like the Mass formula.
