摘要: In this talk I'll first introduce the generalized Kodaira-Spencer maps for a given family. By using those maps we construct a Higgs bundle associated to the family. Then we explain how to use this Higgs bundle and the cyclic covering to find a big subsheaf in some symmetric power of the cotangent sheaf of the base space of the family, which is called the Viehweg-Zuo sheaf.
