本文针对复代数簇上由线丛整体截面定义的有效卡蒂埃除子,用混合霍奇模理论描述其N重循环覆盖的构造方法。
AI 中文摘要
设X为复代数簇(不一定光滑),其上有任意线丛$\u2112$;对正整数N,若存在整体截面$s \u2208 \u0393(X, \u2112^N)$定义有效卡蒂埃除子D,记$\u03c0: Y \u2192 X$为该整体截面s导出的除子D的N重循环覆盖,本文用斋藤盛彦(Morihiko Saito)的混合霍奇模理论描述此循环覆盖。
英文摘要
Suppose we are given an arbitrary line bundle $\mathcal{L}$ on a complex algebraic variety $X$, not necessarily smooth. For a positive integer $N$, suppose there exists a global section $s \in Γ(X, \mathcal{L}^{N})$ that defines an effective Cartier divisor $D$. If we denote $π: Y \rightarrow X$ to be the $N$-fold cyclic covering of the divisor $D$ resulting from the global section $s$, we describe the cyclic covering in terms of Morihiko Saito's theory of mixed Hodge modules.
