Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：与Lamé函数相关的tau函数与顶点算子: KP及其约化
Lamé函数 tau函数 顶点算子 KP约化
2023/5/5
Lamé函数可以视为当势函数取Weierstrass的p函数时Schr?dinger谱问题的解。KdV/KP型的可积系统存在以Lamé函数为平面波因子的精确解。 该报告将介绍KP方程的相关结果、周期退化、色散关系约化、公开问题、等等。

Lamé函数可以视为当势函数取Weierstrass的p函数时Schr?dinger谱问题的解。KdV/KP型的可积系统存在以Lamé函数为平面波因子的精确解。报告将以KdV方程为例，介绍基于Lamé函数的双线性方法框架，包括：椭圆色散关系、双线性方程的拟规范性质、tau函数、顶点算子的椭圆形变、双线性等式。
越来越多的证据记录了2019年冠状病毒病(COVID-19)感染尤其是重症感染引发的神经系统并发症，包括脑血管后遗症、精神分裂症和抑郁症等。鉴于COVID-19大流行的规模，可以预见，数量惊人的COVID-19幸存者可能会面临感染导致的终生神经精神疾病后遗症。冠状病毒对大脑的攻击是多方面的，因此，研究SARS-COV-2感染对神经系统影响的分子机制及愈后康复非常重要。
近日，南方科技大学化学系助理教授贾铁争课题组和宾夕法尼亚大学教授Kozlowski课题组合作研究成果以“Autocatalytic photoredox Chan-Lam coupling of free diaryl sulfoximines with arylboronic acids”为题发表在《自然-通讯》（Nature Communications）上。

Elliptic systems with measurable coefficients of the type of Lamé system in three dimensions
Elliptic systems measurable coefficients
2010/11/22
We study the $3 \times 3$ elliptic systems $\nabla (a(x) \nabla\times u)-\nabla (b(x) \nabla \cdot u)=f$, where the coefficients $a(x)$ and $b(x)$ are positive scalar functions that are measurable an...

Extremal spectral properties of Lawson tori and the Lamé equation
Lawson torus Lawson minimal surfaces extremal metric
2010/11/26
Extremal spectral properties of the Lawson tori are studied. A Law-son torus carries an extremal metric for some eigenvalue j of the Laplace-Beltrami operator. We prove that the metric on a Lawson to...

The use of meteorological analogues to account for LAM QPF uncertainty
quantitative precipitation forecasts meteorological analogues
2009/4/28
Flood predictions based on quantitative precipitation forecasts (QPFs) provided by deterministic models do not account for the uncertainty in the outcomes. A probabilistic approach to QPF, one which a...
