数学学院学术报告Analysis Seminar 2021-06-10报告题目: Weak type (1,1) boundedness of some rough integral operators报告人: 丁勇（北京师范大学）时间： 2021年6月10日（周四）上午10：00-11：00地点: 腾讯会议 ID：767 116 233摘要: In this talk, we will give a weak type (1,1) bound criterion forsingular integral operators with rough kernel. As some applications of this criterion, we show that some impo...

微分动力系统学术报告报告题目: Topological entropy of partially hyperbolic systems with multi 1-D centers报告人：臧运涛(华东师范大学)时间： 2021-06-11 10:30-11:30腾讯会议ID：291 853 315摘要：We consider a $C^1$ partially hyperbolic diffeomorphism on a compact manifold with multi 1-D centers. We prove an entropy formula w.r.t. the volume growth rate of subspaces in the tangent bundle. 报告人简介...
