Abstract:
Finite metric graphs with various types of additional structure occur in many areas of math and science. The set of all graphs with a given structure forms a space, where one moves around the space by deforming the metric. I will discuss the Euler characteristics of various examples, including the moduli-space of connected graphs with fundamental group Fn.
