Let $M$ and $N$ be two compact complex manifolds. We show that if the tautological line bundle ${\mathcal{O}}_{T_{M}^{\ast }}(1)$ is not pseudo-effective and ${\mathcal{O}}_{T_{N}^{\ast }}(1)$ is nef, then there is no non-constant holomorphic map from $M$ to $N$ . In particular, we prove that any holomorphic map from a compact complex manifold $M$ with RC-positive tangent bundle to a compact complex manifold $N$ with nef cotangent bundle must be a constant map. As an application, we obtain that there is no non-constant holomorphic map from a compact Hermitian manifold with positive holomorphic sectional curvature to a Hermitian manifold with non-positive holomorphic bisectional curvature.

全纯映射的 RC 正定性、消失定理和刚性
让$M$ 和$N$ 是两个紧凑的复流形。我们证明如果重言式线丛${\mathcal{O}}_{T_{M}^{\ast }}(1)$ 不是伪有效的并且${\mathcal{O}}_{T_{N}^{\ast }}(1)$ 是 nef,则不存在来自的非常量全纯映射$M$ 到$N$ . 特别是,我们证明了任何来自紧复流形的全纯映射$M$ 具有 RC 正切丛的紧凑复流形$N$ 与 nef 余切丛必须是一个常数映射。作为一个应用程序,我们从一个紧致中得到不存在非常量全纯映射厄米流形 和正全纯截面曲率 到具有非正全纯二等分曲率的 Hermitian 流形。
