| Popis: | We classify rank two vector bundles on a del Pezzo threefold $X$ of Picard rank one whose projectivizations are weak Fano. We also investigate the moduli spaces of such vector bundles when $X$ is of degree five, especially whether it is smooth, irreducible, or fine. Comment: 23 pages; v2: Remark 1.3 added, Proofs in Section 3.5 improved |
