数学科学学院统计与运筹系学术报告Local geometry determines global landscape in low-rank factorization for synchronization凌舒扬 长聘助理教授（上海纽约大学）报告时间： 2023年12月20日 (星期三) 上午10：00-11：00 报告地点：沙河主E404报告摘要：The orthogonal group synchronization problem, which focuses on recovering orthogonal group elements from their corrupted pairwise measurements, encompasses exa...
基础数学系学术报告——代数几何讨论班题目：Slope inequality for fibered threefolds over curves报告人：胡勇 教授（上海交通大学）时间：2023年12月08日 14:00-15:30地点：沙河校区-E座-404西摘要: In this talk, we will introduce the slope inequality for fibered varieties over curves. We will prove that the optimal lower bound of the slope of fibered threefolds over curves is 4/3. If time permits, we wi...
