The ranks of tensors ha... 23 2025-09 分析和微分方程讨论班 报告题目：Unconditional stability of equilibria in thermally driven compressible fluids报 告 人：吕勇 教授（南京大学）时 间：2025年9月27日（星期六），上午10:00-11:00地 点：海纳苑2幢101摘 要：We show that small perturbations of the spatially homogeneous equilibrium of a thermally driven compressible viscous... 23 2025-09 分析和微分方程讨论班 报告人：孙永忠 教授（南京大学）时 间：2025年9月27日（星期六），上午9:00-10:00地 点：海纳苑2幢101摘要： 23 2025-09 组合数学讨论班 报告题目: Maximal determinants of roots of unity matrices报 告 人: Dr Guillermo Ponasso (Tohoku University)时 间: 11:00-12:00, September 26, 2025地 点：820 Haina Complex Building 2摘 要: Hadamard posed the question of determining the maximal determinant of a +/-1 matrix of any given order. A special family of matrices maximizing the deter... 23 2025-09 组合数学讨论班 报告题目: Constructions of distance biregular graphs报 告 人: Professor Akhiro Munemasa (Tohoku University)时 间: 10:00-11:00, September 18, 2025地 点：820 Haina Complex Building 2摘 要: We construct a new family of distance-biregular graphs related to hyperovals and a new sporadic example of a distance-biregular graph related to Mathon'... 22 2025-09 Unconditional stability of equilibria in thermally driven compressible fluids 报告人：吕勇 教授（南京大学）时 间：2025年9月27日（星期六），上午10:00-11:00地 点：海纳苑2幢101 摘 要：We show that small perturbations of the spatially homogeneous equilibrium of a thermally driven compressible viscous fluid are globally stable. Specifically, any weak solution of the evolutionary Navier--Stokes--Fourier system driven by thermal convection converges to ... 17 2025-09 概率统计讨论班 报告题目：ReHLine: Regularized Composite ReLU-ReHU Loss Minimization with Linear Computation and Linear Convergence报 告 人：戴奔 助理教授（香港中文大学）时 间：2025年9月19日（星期五），上午11:00-12:00地 点：海纳苑2幢102摘 要：Empirical risk minimization (ERM) is a crucial framework that offers a general approach to handling a broad range of machine lear... 01 2025-09 动力系统与分形几何讨论班 报告人：曹仕平博士（香港中文大学）报告时间：9月4日下午16:00—17:00报告地点：海纳苑2幢205室摘要：Brownian motions on generalized Sierpinski carpets were constructed by Barlow and Bass as scaling limits of constant time-changed reflected Brownian motions on Euclidean domains approximating the carpet. In this talk, we show that the time scaling can be chosen in the form $\lambda^n$ for some $\lambda&g... 31 2025-07 动力系统讨论班——On the Birkhoff conjecture for nearly centrally symmetric domains 报告人：Vadim Kaloshin （奥地利科技学院）时间：2025年7月31日，10:30-12:00地点：海纳苑2幢203室摘要: In this talk, I will discuss a recent advance on Birkhoff conjecture, namely a proof that : an integrable, nearly centrally symmetric Birkhoff billiard table is necessarily an ellipse. This is done by combining recent breakthroughs by Bialy-Mironov (who prove the conjecture for centrally symmetr... 03 2025-07 几何讨论班 每页 10 记录 总共 1124 记录 第一页 <<上一页 下一页>> 尾页 页码 8/113 跳转到
