几何分析讨论班--Rigidity theorems about Q-curvature

报告人：李明翔 博士 （南京大学）时间：2023年10月10日 （星期二）上午10:30-11:30 地点：海纳苑2幢105摘要：In this talk, we will introduce some rigidity theorems on complete and conformally flat manifolds with help of Q-curvature. We introduce a new volume entropy to give a sufficient and necessary condition for the ”normal” metric. Meanwhile, with help of geometric measure theory, we give a di...

Sticky Kakeya sets in R^3

Title: Sticky Kakeya sets in R^3Abstract: A Kakeya set is a set of points in R^n which contains a unit line segment in every direction. The Kakeya conjecture states that the dimension of any Kakeya set is n. This conjecture remains wide open for all n \geq 3.Together with Josh Zahl, we study a special collection of the Kakeya sets,namely the sticky Kakeya sets, where the line segmen...

Sharp pointwise convergence on the Schrödinger operator along one class of curves

Title: Sharp pointwise convergence on the Schrödinger operator along one class of curvesSpeaker:曹桢斌（北京师范大学）Time:2023-06-08，9:00-11:00Location:腾讯会议 256787687Abstract:Almost everywhere convergence on the solution of Schrödinger equation is an important problem raised by Carleson, which was essentially solved by Du-Guth-Li and Du-Zhang. In this talk, we discuss pointwise convergence o...

L^p bounds for Hilbert transforms along certain variable curves

Title: L^p bounds for Hilbert transforms along certain variable curvesSpeaker:万仁辉（南京师范大学）Time:2023-06-01，9:00-10:00Location:腾讯会议 754117896Abstract:We will show the L^p boundedness of the Hilbert transforms along some variable non-flat curves. The proof is based on the estimate of shift maximal operator and Stein-Wainger-type’s decay estimate by Guo-Pierce-Roos-Yung. Besides, we al...
