Tropical geometry is a relatively new area in mathematics studying metric graphs using combinatorial methods. In this talk, I will present Dhar’s burning algorithm for metric graphs and discuss its underlying algebro-geometric meaning. Additionally, we will apply this algorithm to compute the fibres of the Abel-Prym map associated to graph covers. No prior background in algebraic geometry is needed for this talk, as I will introduce the key concepts the definition of Abel-Prym and give a construction of covers of graphs.
