Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Guo-Jacquet 相对迹公式简介
相对朗兰兹纲领 相对迹公式 Guo-Jacquet
2023/4/23
相对朗兰兹纲领的目标之一是建立自守形式的周期积分（分析对象）与自守 L 函数的特殊值（算术对象）之间的联系。其中一个著名的例子是 Waldspurger 公式，其后被 Jacquet 用比较相对迹公式的办法重新证明。在本报告中，我们打算介绍 Guo-Jacquet 猜想的 Waldspurger 定理的一种高维推广以及用于研究该猜想的相对迹公式。我们将回顾相关背景，概述已知结果，解释其中难点，并讨...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Reciprocity with Uncertainty About Others
互惠 对他人 不确定性
2023/4/21
We introduce the uncertainty of psychological motivation into a reciprocity model and explore its implications on behavior. More precisely, we assume that reciprocity sensitivities are subject to inco...
