AI总结:

本文通过建立统一RC k-正的全纯向量丛的消散定理,证明了具有正k-瑞奇曲率的紧复流形的全纯切丛是统一RC k-正的,并应用该结果证明某些全纯张量场空间的平凡性及紧凯勒流形的有理连通性。

摘要:

本文建立了统一RC k-正的全纯向量丛的消散定理。结果表明,紧复流形上配备正k-瑞奇曲率的凯勒度量的全纯切丛是统一RC k-正的。两个主要应用是:其一,得出某些全纯张量场空间的平凡性,推广了近期结果;其二,证明一个紧凯勒流形若其全纯切丛可赋予统一RC k-正的全纯度量或正k-瑞奇曲率的凯勒类全纯度量,则该流形是有理连通的。

英文摘要:

A vanishing theorem for uniformly RC $k$-positive Hermitian holomorphic vector bundles is established. It turns out that the holomorphic tangent bundle of a compact complex manifold equipped with a positive $k$-Ricci curvature Kähler metric is uniformly RC $k$-positive. Two main applications are presented. The first one is to deduce that spaces of some holomorphic tensor fields on such Kähler or more generally Kähler-like Hermitian manifolds are trivial, generalizing some recent results. The second one is to show that a compact Kähler manifold whose holomorphic tangent bundle can be endowed with either a uniformly RC $k$-positive Hermitian metric or a positive $k$-Ricci curvature Kähler-like Hermitian metric is projective and rationally connected.
