On Chern-Calabi Flows On Compact Complex Surfaces题目:On Chern-Calabi Flows On Compact Complex Surfaces报告人:盛利 教授(四川大学)地点:致远楼101室时间:2025年6月11日 9:30-10:30Abstract:We propose the Chern-Calabi Flow for extremal metrics in conformal Hermitian geometry. We obtain the existence of global flows to the Chern-Calabi flows for extremal metrics on compact complex surfaces with Gauduchon metrics. We also study the convergence...盛利 教授(四川大学)致远楼101室2025年6月11日 9:30-10:30
