Threefolds with nef anticanonical bundles

  • Thomas Peternell
  • Published 1998


In this paper we study the global structure of projective threefolds X whose anticanonical bundle −KX is nef. In differential geometric terms this means that we can find metrics on −KX = detTX (where TX denotes the tangent bundle of X) such that the negative part of the curvature is as small as we want. In algebraic terms nefness means that the intersection… (More)
