Xiao's conjecture for general fibred surfaces

Miguel Ángel Barja, Víctor González-Alonso, Juan Carlos Naranjo

We prove that the genus $g$ , the relative irregularity $q_{f}$ and the Clifford index $c_{f}$ of a non-isotrivial fibration $f$ satisfy the inequality $q_{f} \leq g - c_{f}$ . This gives in…
