As an application we give a proof of Bartnik's stationary vacuum conjecture from 1989 and geometri... 24 2026-04 算子代数讨论班 报告题目: Order zero maps and noncommutative dimensions报 告 人: 吴建超（复旦大学，上海数学中心）时 间: 2026年4月24日,15:00-16:00地 点:海纳苑2幢202摘 要: The standard notion of morphisms between operator algebras is (*-)homomorphisms. A more general notion called c.p.c. order zero maps was introduced by W. Winter and J... 24 2026-04 算子代数讨论班 报告题目: Quasi-local algebras and their projections报 告 人: 章嘉雯（复旦大学）时 间: 2026年4月24日, 14:00-15:00地 点:海纳苑2幢202摘 要: Quasi-local algebras are operator algebras associated with metric spaces, which encode their coarse geometry. They were introduced by John Roe and played an important role in t... 22 2026-04 组合数学讨论班 报告题目: On Closures of Finite Permutation Groups报 告 人: Andrey Vasilev(Novosibirsk State University)时 间: 2026年4月22日, 10:30-11:30地 点:海纳苑2幢820摘 要: Let X be a finite set and k a positive integer. The largest subgroup of the symmetric group Sym(X) having the same orbits as a given subgroup G of Sym(X) in t... 15 2026-04 计算与应用讨论班 报告题目：How AI changed the way of coding, and what math / CS students can learn from it报告人：李绳（Nova Vision）时间：2026年04月15日（星期三），10:30地点：海纳苑2幢202摘要：If we compare the evolution of AI coding tools to changes in payment methods, my workflow over the past year has moved through three stages: “cash” (Q&A and copy‑paste), “credit card” (human–AI collaborati... 14 2026-04 计算与应用讨论班 报告题目：Robust Preconditioners for Multiphysics Problems in Brain Mechanics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 bootstra... 13 2026-04 计算与应用讨论班 报告题目：A posteriori error estimation and adaptivity for the finite element discretization of second-order PDE problems set in unbounded domains报告人：Theophile Chaumont-Frelet（Junior Researcher，Inria）时间：2026年04月13日（星期一），下午15:00地点：海纳苑2幢206摘要：This talk is dedicated to the discretization of second-order PDE problems set in unbounded domains. The approximation procedure ... 10 2026-04 组合数学讨论班 报告题目: Geometric representations of projective spaces and generalized quadrangles报 告 人: Koen Thas(Ghent University)时 间: 2026年4月10日, 09:30地 点:海纳苑2幢303摘 要: (1) Title: Geometric representations of projective linesAbstract: Given a division ring B and a division ring A such that the left dimens... 09 2026-04 分析和微分方程讨论班 报告题目：Derivation of Fokker-Planck-Landau equation from Boltzmann equation by weak-coupling limit报 告 人：何凌冰 教授（清华大学）时 间：2026年4月9日，14:00-15:00地 点：海纳苑2幢204摘 要： Conventional literature on physical books asserts that starting with any smooth potential function $\Phi(|... 08 2026-04 计算与应用讨论班 报告题目：双曲守恒律的间断有限元方法研究报告人：谢正荣（华东师范大学）时间：2026年04月08日（星期三），下午15:00地点：海纳苑2幢203摘要：本次报告主要分为两部分: (1) 首先重点考察了一种半拉格朗日间断有限元 (CSLDG), 用以求解线性标量输运方程(LSTEQ). 将CSLDG中的积分不变量模型 $\int_{\widetilde{\Omega}(t)} U \psi d \mathbf{x}=0$ 作为 LSTEQ 的一种非标准 Galerkin 弱形... 每页 10 记录 总共 1109 记录 第一页 <<上一页 下一页>> 尾页 页码 3/111 跳转到
