%0 Journal Article %T Threefolds with nef anticanonical bundles %A Thomas Peternell %A Fernando Serrano %J Mathematics %D 1998 %I arXiv %X We prove that the Albanese map of a smooth projective threefold, whose anticanonical bundle is nef, is a surjective submersion. We also investigate morphisms of threefolds to curves and surfaces whose relative anticanonical bundle are nef. %U http://arxiv.org/abs/math/9802024v2
