Brill-Noether theory of curves on ${\mathbb{P}}^1\times {\mathbb{P}}^1$: tropical and classical approach

Filip Cools, Michele D'Adderio, David Jensen +1

The gonality sequence $(d_r{)}_{r\ge 1}$ of a smooth algebraic curve comprises the minimal degrees $d_r$ of linear systems of rank $r$. We explain two approaches to compute the gonal…
