Abstract

Green’s Conjecture is proved for smooth curves \(C\) lying on a rational surface \(S\) with an anticanonical pencil, under some mild hypotheses on the line bundle \(L=\mathcal{O }_S(C)\). Constancy of Clifford dimension, Clifford index and gonality of curves in the linear system \(\vert L\vert \) is also obtained.
