Abstract

Let $f\: X \to Y$ be a degree $k$ covering of smooth and connected projective curves with $p_a(Y)>0$. Here we continue the study of the Brill-Noether theory of divisors on $X$.

Keywords: Covering of curves; gonality; scrollar invariant; hyperelliptic curve; Brill-Noether theory; ruled surface.
