题 目：Nevanlinna Theory and hyperbolicity of moduli spaces

摘 要：Nevanlinna theory plays a very important role in complex hyperbolic geometry. The study of hyperbolicity of moduli spaces of polarized varieties can be traced back to Shafarevich's 1962 ICM conjecture for the moduli space of curves. In this talk I will explain the connection between Nevanlinna theory and hyperbolicity of moduli spaces.

题 目： Non-archimedean hyperbolicity on moduli spaces
时 间：2020.10.22（星期四），9:00-11:00
地 点：中科院数学院南楼N212
摘 要：It has been noticed for a long time that one can develop an analogue of Nevanlinna theory over non-archimedean fields. It is relatively little known results about non-archimedean hyperbolicity. In this talk, we introduce some notions of non-archimedean hyperbolicity, and verify them on the moduli space of curves.

题 目： On Campana's Isotriviality Conjecture and related questions
时 间：2020.10.22（星期四），15:00-17:00
地 点：中科院数学院南楼N226
摘 要：Campana introduced the notion of special variety to reflect properties which are "opposite" to those of varieties of general type. He conjectured that a family of polarized varieties over a special base is isotrivial. In this talk, we discuss some question motivated by this conjecture.
