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... 20 2023-09 Zeta Functions of Shimura Varieties: Past, Present, and the Near Future 数论与表示论讨论班Number Theory and Representation Theory SeminarTime: June 21, Wednesday, 16:00-17:00 Venue: Lecture HallSpeaker:Yihang Zhu朱艺航(University of Maryland) Title: Zeta Functions of Shimura Varieties: Past, Present, and the Near FutureAbstract: I will first recall the general expectations of Shimura, Langlands, and Kottwtiz on the shape of the zeta function of a Shimura variety, or... 20 2023-09 Parameter space of cubic polynomials with a parabolic fixed point Title: Parameter space of cubic polynomials with a parabolic fixed pointAbstract: We study the topological structure of the parameter space for the cubic polynomial family \lambda z+az^2+z^3 when \lambda is a root of unity. We show that for any given \lambda, the connected locus in the a-plane contains a full continuum which is almost a double covering of the filled-in Julia set for the quadratic ... 13 2023-06 School Colloquium—Moduli space of Einstein metrics: topology, analysis, and metric geometry 13 2023-06 Stability scattering diagrams and quiver coverings 学术报告题目:Stability scattering diagrams and quiver coverings报告人:覃帆 教授(上海交通大学数学学院)时间:2023年6月14日星期三下午1:30---2:30地点:浙江大学紫金港校区海纳苑2栋210室摘要:In this talk, we introduce nice gradings associated to quiver coverings. We explain that Bridgeland’s stability scattering diagrams respect quiver coverings if nice grading exist. In particular, our results app... 13 2023-06 Connectedness of Hurwitz spaces and strong approximation for the Markoff equation 20 2023-09 Subspace learning for high dimensional tensor data 题目:Subspace learning for high dimensional tensor data报告人:韩岳峰(美国圣母大学)时间:2023年6月16日(周五)16:00 地点:海纳苑2幢312摘要:Motivated by modern scientific research, analysis of tensors (multi-dimensional arrays) has emerged as one of the most important and active areas in modern statistics and data science. High-dimensional tensor data routinely arise in a wide range of... 21 2023-09 波方程在调和分析中的若干应用 题目: 波方程在调和分析中的若干应用报告人: 颜立新(中山大学)时间: 2023-06-19,9:15-10:10地点: 腾讯会议:707-961-627摘要:本报告中,我们将探讨波方程解的若干性质,以及它在奇异积分、函数空间、乘子理论等调和分析若干问题中的应用。报告人简介:颜立新,中山大学数学学院教授,博士生导师。国家杰出青年基金获得者, 国务院政府特殊津贴专家。长期从事调和分析领域的研究,在与微分算子相联... 20 2023-09 Symposium on Number Theory and Representation Theory, VI 数论与表示论会议, VI 08 2023-06 Fundamental forms of algebraic varieties Title: Fundamental forms of algebraic varietiesSpeaker: Prof. Wenbo Niu (University of Arkansas)Time: 2023. 06.13, 16:00-17:00Location: 海纳苑2幢204Abstract: Fundamental forms can be thought of as linear systems attached to the projectivization of Zariskitangent space at a nonsingular point of a variety. It was developed by the method of moving frames indifferential geometry. In 1979, Griffths-Har... 每页 10 记录 总共 1034 记录 第一页 <<上一页 下一页>> 尾页 页码 12/104 跳转到
