题目:Projective manifolds whose tangent bundle contains a strictly nef subsheaf

报告人:欧文浩 副研究员

摘要 :

After a theorem of Andreatta and Wisniewski, if the tangent bundle of a projective manifold $X$ contains an ample subsheaf, then $X$ is isomorphic to the projective space. We show that, if the tangent bundle contains a strictly nef subsheaf, then X is a projective bundle over a hyperbolic manifold. Moreover, if the fundamental group of $X$ is virtually abelian, then $X$ is isomorphic to a projective space. This is joint with Jie Liu and Xiaokui Yang.
