论文摘要
我们构建示例，以表明在有限分支的盖子下没有保留Nef cotangent束。我们的示例还表明，带有Stein通用覆盖的投影歧管可能没有Nef Cotangent捆绑包，因此反驳了Liu-Maxim-Wang的猜想。
We construct examples to show that having nef cotangent bundle is not preserved under finite ramified covers. Our examples also show that a projective manifold with Stein universal cover may not have nef cotangent bundle, disproving a conjecture of Liu-Maxim-Wang.
