| Résumé | A del Pezzo threefold F with maximal Picard number is isomorphic to P-1 x P-1 x P-1. In the present paper we completely classify locally free sheaves of rank 2 such that h(i)(F, epsilon(t)) = 0 for i = 1,2 and t is an element of Z. Such a classification extends similar results proved by E. Arrondo and L. Costa regarding del Pezzo threefolds with Picard number 1. (C) 2015 Elsevier Inc. All rights reserved. |
