On the gonality of stable curves

In this paper we use admissible covers to investigate the gonality of a stable curve \(C\) over \(\mathbb{C}\). If \(C\) is irreducible, we compare its gonality to that of its normalization. If \(C\) is reducible, we compare its gonality to that of its irreducible components. In both cases we obtain...
