Abstract

Let Y be a non‐normal del Pezzo surface over β„‚ and let d ≔ (Ο‰^βˆ’1^~Y~)^2^ > 0 be the degree of Y. Then we prove that Ο‰^βŠ—dβˆ’4^~Y~ is very ample for d = 1, 2.

## Abstract We classify all cases of exceptional curves on Del Pezzo surfaces, which turn out to be the smooth plane curves and some other cases with Clifford dimension 3. Moreover, the property of being exceptional holds for all curves in the complete linear system. We use this study to extend the

## Abstract Let __L__ be a nef line bundle on a Del Pezzo surface. We show that __L__ + __K~S~__ is birationally __k__–very ample if and only if all the smooth curves in |__L__| have gonality β‰₯__k__ + 2, and we also find numerical criteria for birational __k__–very ampleness.
