Notes on the values of volume entropy of graphs
Woo-Yeon Kim, Seonhee Lim · Discrete and Continuous Dynamical Systems · 2020
Volume entropy is an important invariant of metric graphs as well as Riemannian manifolds. In this note, we calculate the change of volume entropy when an edge is added to a metric graph or when a vertex and edges around it are added. In the second part, we estimate the value of the volume entropy which can be used to suggest an algorithm for calculating the persistent volume entropy of graphs.
