Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Peak distributions and peak maps in lattice paths
晶格路径 峰分布 峰图

Dyck paths are classical Catalan objects. The peak distribution of Dyck paths is an important topic of combinatorics, and further the representation of symmetric groups.
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Pseudorandomness of Sato-Tate Distributions for Elliptic Curves
椭圆曲线 佐藤-泰特分布 伪随机性
2023/4/13
Equidistribution is an important theme in number theory. The Sato-Tate conjecture, which was established by Richard Taylor et.al. in 2008, asserts that given an elliptic curve over Q without complex m...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Lines on holomorphic contact manifolds and a generalization of (2,3,5)-distributions to higher dimensions
全纯接触流形 线和 （2，3，5） 高维度推广
2023/4/19
Since the celebrated work by Cartan, distributions with small growth vector (2,3,5) have been studied extensively. In the holomorphic setting, there is a natural correspondence between holomorphic (2,...

栖息地片段化是导致生物多样性丧失的最主要因素之一，身体大小是影响各种动物类群生活史特征、种内和种间关系等生态过程的重要的形态学特征，身体大小在空间和时间上的差异是动物普遍存在的环境适应结局。与大陆种群相比，许多动物类群的岛屿种群在形态及身体大小上会出现非常显著的变化。丁平教授课题组基于“岛屿规律”和动物形态快速进化等研究背景，以千岛湖片段化栖息地为研究平台，开展人类活动造成片段化栖息地中动物身体大...
