Recognizing hyperelliptic graphs

Marieke van der Wegen (Universiteit Utrecht)

 

Based on analogies between algebraic curves and graphs, a new multigraph parameter was defined. This parameter is called divisorial gonality and can be defined using a chip-firing game. In this talk we consider so-called hyperelliptic graphs, which are graphs with divisorial gonality 2. We will see that we can decide in polynomial time whether a graph is hyperelliptic or not.
