%0 Journal Article %T Inequalities between the Chern numbers of a singular fiber in a family of algebraic curves %A Jun Lu %A Sheng-Li Tan %J Mathematics %D 2010 %I arXiv %X 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. %U http://arxiv.org/abs/1003.1767v1
