论文摘要
假设$ x $是一个投影歧管，其切线捆绑$ t_x $包含本地免费的严格nef子展。我们证明，$ x $是双曲线歧管上的投影捆绑包的同构。此外，如果基本组$π_1（x）$几乎是阿贝里安（Abelian），则$ x $对投射空间是同构的。
Suppose that $X$ is a projective manifold whose tangent bundle $T_X$ contains a locally free strictly nef subsheaf. We prove that $X$ is isomorphic to a projective bundle over a hyperbolic manifold. Moreover, if the fundamental group $π_1(X)$ is virtually abelian, then $X$ is isomorphic to a projective space.
