We show that if the weights of the zero variance portfolio are learned by a novel “Ridgelet” estimator, i... 29 2026-05 计算与应用讨论班 报告题目：An energy- and helicity-conserving enriched Galerkin method for the incompressible Navier-Stokes equations报告人：张倩（吉林大学）时间：5月29日14：00-15：00地点：海纳苑2幢312报告摘要：In the ideal limit and in the absence of external forces, the incompressible Navier–Stokes equations preserve fundamental invariants, including kinetic energy and helicity. From a numerical perspective, fai... 28 2026-05 计算与应用讨论班 报告题目：Distributional Finite Element Complexes and Applications to Partial Differential Equations报告人：黄学海（上海财经大学，教授）时间：5月28日16：00-17：00地点：海纳苑2幢101摘要：In this talk, we begin with the development of distributional finite element complexes, including the distributional div div and curl div complexes. In the main part of the talk, we discuss applications of these co... 21 2026-05 计算与应用讨论班 报告题目：On Algorithmic Stability and Robustness of Bootstrap SGD报告人：Andreas Christmann（University of Bayreuth, Germany）时间：2026年05月21日（星期四），15:00地点：海纳苑2幢204摘要：The bootstrap is a computer-based resampling method that can provide good approximations to the finite sample distribution of a given statistic. In this talk some methods to use the empirical bootstrap approach f... 18 2026-05 分析和微分方程讨论班 报告题目：Quantitative classification of potential Navier-Stokes singularities beyond the blow-up time报 告 人：Tobias Barker教授 ( University of Bath )时 间：2026年5月19日（星期二），下午15:00-16:00地 点：海纳苑2幢202摘 要：It remains an open problem whether or not solutions to the 3D Navier-Stokes equations with smooth data remain smooth for all time. All p... 22 2026-05 代数与表示论讨论班 28 2026-05 分析和微分方程讨论班 报告题目：Smoothing estimates for wave equations报告人：吴澍坤(印第安纳大学)时间：2026年5月28日，15:30地点：海纳苑2幢204 摘要：The local smoothing conjecture for wave equations was raised by Sogge, initially aiming to understand Stein's spherical maximal function. Because of its close connection to the Fourier transform of the surface measure of t... 12 2026-05 计算与应用讨论班 报告题目：A Warm-basis Method for Bridging Learning and Iteration: a Case Study in Fluorescence Molecular Tomography报告人：姜嘉骅（上海科技大学，副教授）时间：5月14日16：00-17：00地点：海纳苑2幢202摘要：Fluorescence Molecular Tomography (FMT) is a widely used non-invasive optical imaging technology in biomedical research. It usually faces significant accuracy challenges in depth reconstructi... 07 2026-05 代数与表示论讨论班 报告题目: Modular tensor categories and 3D-TFTs报 告 人: 王亦龙 博士 (北京雁栖湖应用数学研究院)时 间: 2026年5月7日，16:00-17:30地 点:海纳苑2幢204摘 要: Modular tensor categories (MTCs) play an important role in the study of 3-dimensional topological field theories (TFTs). They possess rich algebraic properties that man... 05 2026-05 2026 年 5 月浙江大学分形几何小型Workshop 每页 10 记录 总共 1145 记录 第一页 <<上一页 下一页>> 尾页 页码 2/115 跳转到
