Threefolds of non negative Kodaira dimension with sectional genus less than or equal to 15
Threefolds with big and nef anticanonical bundles II
In a follow-up to our paper [Threefolds with big and nef anticanonical bundles I, Math. Ann., 2005, 333(3), 569–631], we classify smooth complex projective threefolds Xwith −K X big and nef but not ample, Picard number γ(X) = 2, and whose anticanonical map is small. We assume also that the Mori contraction of X and of its flop X + are not both birational.
Threefolds with nef anticanonical bundles.
In this paper we study the global structure of projective threefolds X whose anticanonical bundle -KX is nef.
