计算与应用讨论班——Low-degree finite element methods for transmission eigenvalue problems
报告人：张硕(中科院数学与系统科学研究院)时间：2025年5月23日，14:00-16:00地点：海纳苑2幢203室摘要：The transmission eigenvalue problem is applied in invisibility cloaking, seismic exploration, photonic crystals and meta-surfaces. As a fourth order nonlinear eigenvalue problem with variable coefficient, conforming finite element discretization requires high-degree polynomials. In this talk, we utili...

概率统计讨论班——High-dimensional central limit theorems by Stein's method in the degenerate case
报告人：方笑（香港中文大学）时间：2025年5月24日，10:00-11:00地点：海纳苑2幢206室摘要：In the literature of high-dimensional central limit theorems, there is a gap between results for general limiting correlation matrix $\Sigma$ and the strongly non-degenerate case. For the general case where $\Sigma$ may be degenerate, under certain light-tail conditions, when approximating a normalized sum of $n$...

数论与表示论讨论班—— Positivity of Fourier transform of zonal spherical functions
报告人：余君（北京大学）时间：2025年5月13日，10:30-11:30地点：海纳苑2幢203室摘要：Given a semisimple real linear group, a zonal spherical function is matrix coefficient associated to the unique spherical vector with value 1 at identity element in a unitary spherical principal series, which are important object in representation theory and harminic analysis. Each zonal spherical function is a posit...
