地 点：中科院数学院南楼N224
摘 要：For algebraic fiber spaces, the direct image of relative dualizing sheaves are important. In this talk, I will explain how to use tools from Hodge theory to study positivity property of direct image sheaves, and some application of it.

题 目： Tautological inequality and Second Main Theorem
时 间：2020.11.04（星期三），17:00-19:00
地 点：中科院数学院南楼N224
摘 要：Logarithmic Derivative Lemma plays a crucial role in Nevanlinna's original proof of his second main theorem. In higher dimension situation, McQuillan's tautological inequality can be regarded as a suitable generalization of it. In this talk, I will explain the tautological inequality and its relation to the second main theorem.
