Inequalities between the Chern numbers of a singular fiber in a family of algebraic curves

Jun Lu, Sheng-Li Tan

摘要:

在曲线族中,奇异纤维的Chern数是对全空间的Chern数的局部贡献。本文给出了奇异纤维的Chern数之间的一些不等式以及它们的上下上界。引入了奇异纤维的对偶纤维,并证明了一个对偶定理。作为一个应用,我们将分类的奇异纤维与大或小陈数。

英文摘要:

In a family of curves, the Chern numbers of a singular fiber are the local contributions to the Chern numbers of the total space. We will give some inequalities between the Chern numbers of a singular fiber as well as their lower and upper bounds. We introduce the dual fiber of a singular fiber, and prove a duality theorem. As an application, we will classify singular fibers with large or small Chern numbers.
