报告二


报告题目: Optimal L^2 Extensions of Openness Type and Related Topics

报告时间:2023年6月17日上午10:40-11:40

报告地点:数学楼122

报告摘要: In this talk, I will present several optimal L^2 extension theorems of openness type on weakly pseudoconvex Kähler manifolds, which generalize a couple of known results. I will also present some applications to related topics, such as characterizations of Griffiths positivity, the product property for minimal L^2 extensions and the equality part of Suita's conjecture. This talk is mainly based on the joint works with Prof. Xiangyu Zhou.

报告题目: Strong Openness of Multiplier Submodule Sheaves Associated to Nakano Semi-positive Singular Hermitian Metrics

报告时间:2023年6月17日下午14:00-15:00

报告地点:数学楼122

报告摘要: Let E be a holomorphic vector bundle endowed with a Nakano semi-positive singular hermitian metric h. Then the multiplier submodule sheaf associated to (E,h) satisfies strong openness, which means that if for any holomorphic section u with |u|^2_h is integrable locally, then there exists p>2 such that |u|^p_h is integrable locally. This is a joint work with Zhuo Liu and Xiangyu Zhou.
