This is a work joint with Yuchen Bi from the University of Freiburg. 28 2026-05 计算与应用讨论班 报告题目： Variational-Hemivariational Inequalities: Theory, Numerical Analysis, and Applications报告人：Weimin Han（Department of Mathematics, University of Iowa, Iowa City, IA 52242, USA）时间：2026年5月28日14：00地点：海纳苑2幢202报告摘要：In recent years, modeling, mathematical analysis, and numerical solution of hemivariational inequalities, or more generally, variational-hemivariational ineq... 27 2026-05 计算与应用讨论班 报告题目： Efficient Algorithms for A Linear Thermo-Poroelastic Model报告人：Mingchao Cai (Morgan State University, Professor)时间：2026年5月27日14：30-15：30地点：海纳苑2幢204报告摘要：Thermo-poroelastic models capture the interplay between elastic porous material deformation, fluid flow, and thermal effects under non-isothermal conditions. This talk presents a four-field formulation for the... 26 2026-05 几何分析讨论班 报告题目：Singularity removal rigidity theorem for minimal hypersurfaces with isolated singularities in manifolds of nonnegative scalar curvature报 告 人：于浩斌 教授（杭州师范大学）时 间：2026年6月3日（星期三），上午9:30-10:30地 点：海纳苑2幢205摘 要：In this talk we will present the “Singularity removal rigidity theorem” for minimal hypersurfaces with isolated ... 15 2026-06 概率统计讨论班 报告题目：Zero Variance Portfolio报告人：史震涛（香港中文大学）时间：2026年6月15日16：30-17：30地点：海纳苑2幢206报告摘要：When the number of assets is larger than the sample size, the minimum variance portfolio interpolates the training data, delivering pathological zero in-sample variance. 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.
