Abstract

We give a new proof that every holomorphic one-form on a smooth complex projective variety of general type must vanish at some point, first proven by Popa and Schnell using generic vanishing theorems for Hodge modules. Our proof relies on Simpson's results on the relation between rank one Higgs bundles and local systems of one-dimensional complex vectors spaces, and the structure of the cohomology jump loci in their moduli spaces.
全纯一形式的Kodaira维数和零点,重访
我们给出了一个新的证明,即一般类型的光滑复射影变种上的每一个全纯一形式都必须在某个点上消失,首先由Popa和Schnell利用Hodge模的一般消失定理证明了这一点。我们的证明依赖于Simpson关于秩为1的Higgs丛与一维复向量空间的局部系统之间的关系的结果,以及它们的模空间中的上同调跳跃轨迹的结构。
