分析和微分方程讨论班

报告人：简昌彪（中国工程物理研究院）时间：2025年7月5日，09:30-10:30地点：海纳苑2幢203室摘要:For a smooth $k$-dimensional submanifold $\Sigma$ of a $d$-dimensional compact Riemannian manifold $M$, we will discuss how to extend the $L^p(\Sigma)$ restriction bounds of Burq--Gérard--Tzvetkov \cite{bgt2007}—originally proved for individual Laplace--Beltrami eigenfunctions—to arbitrary systems of $L^2(...

分析和微分方程讨论班

报告人：王兴（湖南大学）时间：2025年7月5日，11:00-12:00地点：海纳苑2幢203室摘要:Marzo and Ortega-Cerd`a gave geometric characterizations for L^p-Logvinenko-Sereda sets on the standard sphere. Later, Ortega-Cerd`a and Pridhnani further investigated L^2-Logvinenko-Sereda sets and L^2-Carleson measures on compact manifolds without boundary. In this paper, we characterize L^p-Logvinenko-Sereda s...

报告人：侯家齐（路易斯安那州立大学）时间：2025年7月3日，10:30-11:30地点：海纳苑2幢203室摘要:Let X be a compact congruence arithmetic hyperbolic 3-manifold and let Y be a totally geodesic surface in X. We let f be a Hecke-Maass form on X, which is a joint eigenfunction of the Laplacian and the Hecke operators. I will talk about the asymptotic behavior of f when its Laplace eigenvalue is large, espe...

分析和微分方程讨论班——Strichartz estimates for the Schrödinger equation on the sphere

报告人：黄晓琦（路易斯安那州立大学）时间：2025年7月3日，9:30-10:30地点：海纳苑2幢203室摘要：We will discuss optimal space-time estimates in $L^q_{t,x}$ spaces for solutions to the Schrödinger equation on the standard round sphere, which is related to the results of Burq, Gérard and Tzvetkov (2004). The proof is based on the arithmetic properties of the spectrum of the Laplacian on the sphere, as ...

分析和微分方程讨论班——On almost everywhere convergence of planar Bochner Riesz mean

报告人：吴澍坤（印第安纳大学）时间：2025年5月21日，09:00-10:30地点：海纳苑2幢202室摘要：In this talk, I will survey the almost everywhere convergence problem for the Bochner-Riesz means, and discuss a recent result with Xiaochun Li, where we prove that the planar Bochner Riesz means converge almost everywhere for any L^p function in the optimal range, for 5/3<p<2. One main difficulty of this...

分析和微分方程讨论班——Restriction Problems in the Study of Eigenfunctions

报告人：高传伟（首都师范大学）时间：2025年5月21日，10:30-12:00地点：海纳苑2幢202室摘要：In this talk, we will begin with a brief overview of the restriction problem and its related topics, including the Kakeya problem, decoupling theory, and associated methods and techniques. We will then discuss how these problems connect to the study of eigenfunctions.联系人：席亚昆（yakunxi@zju.edu.cn）

分析和微分方程讨论班——ON THE REGULARITY OF THE SOLUTION OF SOME NONLINEAR PROBLEMS

报告人：Michel Marie Chipot（瑞士苏黎世大学）时间：2025年4月16日，11:00-12:00地点：海纳苑2幢106摘要：The goal of this talk is to present regularity results regarding problems of the type −∆u + β(u − ϕ) = 0 in Ω, u = 0 on ∂Ω which depend only on ϕ and not on the monotone function β. This uses nice techniques developed by H. Brezis and collaborators. (Joint work with David Kinderlehrer)报告人简介...

分析和微分方程讨论班——Triangles and triple products of Laplace eigenfunctions

报告人：Emmett Wyman（纽约宾汉普顿大学）时间：2025年3月26日，09:30地点：ZOOM（923 5610 7458，密码：160721）摘要：At what frequencies does the product of two Laplace-Beltrami eigenfunctions on a manifold concentrate? Equivalently, given three eigenfunctions, how large is the integral of their product over the manifold? In this talk, we provide a relatively complete answer to this question, and in t...

分析和微分方程讨论班——Singular scaling limits from kinetic to macroscopic models: self-organization system vs Boltzmann

报告人：江宁（武汉大学）时间：2024年12月6日（周五）14:30-15:30地点：海纳苑2幢101摘要：In this talk, we introduces two types of singular scaling limits: self-organization kinetic (SOK) and its limit to self-organization hydrodynamics (SOH), and the more traditional Boltzmann equation and its fluid limits. We will review what are singular scaling limits are, the similarities and differences between ...
